Title: EONA ADRaudio merged
Post by: Bennett Prescott on October 18, 2006, 06:01:03 pm
Back in April of this year (in fact, half a year ago now to the day!) I got a quite unexpected PM from a guy I'd never heard of living in a country I'd never heard of. He said he was a high-end powered enclosure manufacturer and that, after much research on the LAB, had decided that he'd like to send me a small PA to evaluate. I was initially so taken aback that I posted on another board asking for advice ? this sort of thing had never happened to me before.

I started a dialogue with the man, who turned out to be Alex Dravinec, head of R&D at EONA ADRaudio in Slovenia and not the least bit crazy. He ended up sending me 6 loudspeakers which I have since used on a large number of shows in varying capacities to great effect, from which base of experience I now write you.

That's him on the right, with Bink in the middle and Franci Pavlin, general manager of the company, to the left.
http://www.campuspa.com/images/aes2006/index-Thumbnails/0.jpg

I need to preface the rest of this Road Test by stating that this is unlike any Road Test that I have conducted so far. First of all, these products aren't widely available in the US yet. If you order them, you can get them, but there will be lag while they get shipped from Slovenia... there will be stock in the US by the end of the year, though. Secondly, I get to keep these boxes, which is not at all SOP for this forum. Thirdly, I have built such a strong working relationship with this manufacturer at this point that this will be the last product review I do for them. If you are interested in hearing their products (either those I have or those that are coming) and perhaps even writing them up here, please contact me. I'm not employed by them, but I believe I have a reputation for fairness and I'd like to keep it.

So take what I say with a grain of salt. I like to think I can remain objective, but I will make every effort to get these speakers into the hands of other LABsters that do not have my business connection with this manufacturer. Good or bad, I want to hear other opinions and I'd hope you would too!

The Actual Review


I received two each of the U103 HH, M1225 HH, and ATA118 HH. The HH stands for "High Headroom" and if you look at the amplifier power listed in the spec sheets you'll understand why. I'll leave out the HH from now on, though, since I think you get the point. Each box is powered, with Neutrik Powercon and XLR in and through, indicators for power, signal and limit on each bandpass, and a re-settable circuit breaker on the back.

The model numbers are pretty easy to turn into an idea of the specs... the U103 is a small trap box with a 10" LF driver and a 3" VC HF driver on a 1.4" exit 75x55 degree rotatable horn. It's got four M10 rigging points, two on top and two on bottom, as well as a pole mounting hole. The box has over 1,200 watts of Bang & Olufsen ICEpower amplification built in (at the load presented by the B&C speakers inside) with a linear power supply and all analog processing, including phase alignment, EQ, crossover, and limiting. Frequency response is 65hz (the box has a 12db/8ve Butterworth HPF at about 70hz) to 17Khz. The acoustic crossover point between the HF and LF drivers is 890hz, also 12db/8ve. This shallow slope allows driver interaction for octaves on either side of the cross point that Alex says a pain to manage with EQ and all-pass filter phase adjustment, but the end result is a box that's extremely linear on and off axis.

Here's a shot with the cover off and on:
http://www.campuspa.com/images/eonaadraudio/index-Thumbnails/4.jpghttp://www.campuspa.com/images/eonaadraudio/index-Thumbnails/7.jpg

As you can see, it's got a very large horn that lets it maintain directivity much better than most boxes even larger than it. This speaker is extremely solidly constructed... I've abused it a bunch over the last 6 months and it's taken it without complaining. It weighs just under 60lbs, partly due to the large toroidal transformer in the power supply, but the unit is easy to carry thanks to its small size and generous handles. The grille is stamped steel 1.5mm thick, powder coated, and can take a pretty good amount of abuse, although I had soft covers made for these boxes soon after I received them because they see more shows than anything else I own and I'd like to keep them pretty. Alex takes durability and reliability extremely seriously, his largest customer right now is a soundco in his area that really abuses the gear day in and day out, so the design specs for all EONA ADRaudio's offerings have been honed down in the real world, and then even further once I'd had them for a little while. This is one designer who spends plenty of time out running shows with national acts on his gear, pushing it to see where he needs to refine it.

Of course, what you really care about is the sound quality and capabilities of this compact little box. I don't attach my name to many products, so I hope it is telling that I say this so clearly now: This may be the best sounding speaker I have ever heard. I haven't yet directly compared it to the EAW NT series, but I think that's the only trap I've heard that's in the same league. The clarity and extension of the high frequencies even while pounding the limiters is extraordinary... this is one of those speakers that reveals details in everything you put through it you'd never known were there. I do a lot of lighter music; jazz and classic rock and acoustic and choirs, and I am now capable of a whole new level of results that I have been unable to attain with any number of other systems I've owned or used.

If you like speakers that sound "big" and add a lot of something to the sound, walk away from these products. They are so linear, so up close and personal, it's breathtaking.

Don't think that because they're small and crystal clear you won't be able to get a lot of SPL out of them, however, the box is rated to 129dB at one meter. Reference these two SPL readings I made at FOH (50' back) and the end of the seating area (100' back) in an 800 capacity tent outdoors. The show was a track act with a lot of percussion, and the boxes were blinking their limit lights... but they had a bunch left, as I discovered during the gospel show I had the next weekend (105 at FOH! Crap!).

(I had to split this into two messages because of a limit on the number of images allowed)

The ATA118 is a single 18" driver in a ported enclosure, backed by over 1400 watts, weighing in at 99lbs. The driver is also from B&C, as are all the drivers in the current and expected future product line. It operates from a little below 30hz to over 100hz, although I tend to cross it out around 70hz. The built in LPF is at 90hz. It'll do 131dB at 1 meter, with peaks considerably higher than that courtesy of the significant amplifier power in the box. That's that "high headroom" concept you see in their literature... there's enough amp in the box to blow up the driver if used continuously, so the limiters clamp down on long-term waves but pass transients. That means that, for instance, kick and snare hits come through crystal clear because they've got another 6dB or so headroom past the limiters before they run into the amp rails, but then the limiters kick in and haul the signal back below "explode". The R&D department goes through more than their fair share of drivers getting that set correctly.

Here are some photos of that box, too:
http://www.campuspa.com/images/eonaadraudio/index-Thumbnails/8.jpghttp://www.campuspa.com/images/eonaadraudio/index-Thumbnails/9.jpg

Before these subwoofers, I hadn't been spoiled by a system able to do much of anything below 40hz. My very first show with them was a jazz quintet outdoors, playing for my old high school's graduation picnic (I pitch in to help them out from time to time, this happened to be especially convenient). During the first piece, the bassist started walking down the scale... and kept going... and going. I'm now convinced I'd never heard that low string before, and being able to reproduce it for several hundred people strewn around a large area outdoors was a wonderful experience. Of course, when I bring the dogs indoors for rock having that extra half octave on the low end for kick makes it enormous, and they're so dynamic in general that it's easy to get knock-you-over low end. Since they're practically impossible to blow up (trust me, I've tried) I occasionally find myself boosting very low frequencies just to add some depth, since I know they'll handle it. Worst case I'll run into the limiters, and they're very transparent.

To give you an idea of size, here's a shot of those subs in use and, um, modeled by Stacy, who's about 5'8" and unavailable:
http://www.campuspa.com/images/eonaadraudio/index-Thumbnails/27.jpghttp://www.campuspa.com/images/adraudio/index-Thumbnails/22.jpg

A word about current draw... I've had all 6 boxes on a single 20a breaker, pounding along for an indoor rock show, and it didn't trip.


Compact and high output is the name of the game so far, so let's continue that vein with the M1225 stage monitor. This low-profile wedge has 1,100 watts running into a coaxial 12" LF and 1.4" exit HF driver that has a 60 degree conical pattern. The design goal with this box was to build the clearest, most stable wedge possible with more than adequate SPL... but weighing less than 50lbs, amplification included!

At just under 42 lbs and capable of 129dB (with peaks up to 138dB as we discovered at WedgeFest!) I'd say that goal was more than satisfied. It's limited by the power handling of the neodimium woofer, which only takes 200 watts but also only weighs 9lbs including the HF driver. The wedges at WedgeFest had an additional 3dB HF boost to make them "cut" more, which we have since removed because, while I love it for a acoustic music, rock guys hate it, and it does harm the stability of the wedge. Otherwise, the wedge is high passed at 80hz and operates all the way up to 16Khz. Since it's always going to be on a stage (it is not flyable and has no pole mount cup) it manages to have a very present and full low end response courtesy of half-space loading... I've used it stand-alone as a drum monitor and it was quite effective.

It was kind enough to pose for me for a few shots:
http://www.campuspa.com/images/eonaadraudio/index-Thumbnails/3.jpghttp://www.campuspa.com/images/eonaadraudio/index-Thumbnails/1.jpg

This is the piece of the PA that I've got the least time listening to, since I'm usually not on stage when the band's going. It gets plenty of compliments from artists, though, and it makes my stages look really clean and neat. I certainly like it because it gives me between 3 and 6db better feedback rejection than my other wedges, gets louder, and meshes extremely well with my mains. My other wedges have a 250hz tubbiness that really muddies up FOH, so I have to cut it out but it's still obvious when the wedges get too hot relative to FOH. With the M1225 they can be quite loud but they don't toss a lot of energy behind them, and even when I'm getting hit at FOH with reflections off a wall it's hard to tell that it's not just more mains.

In fact, I've even used them as front fills to great effect.
http://www.campuspa.com/images/eonaadraudio/index-Thumbnails/18.jpg

The M1225 was also designed to be used in multiples... if you like the fact that it's lightweight (it's easy for one person to pick two up and walk around) and extremely hi-fi, but need more SPL, add a few more wedges. You'll get some "free" LF coupling and, of course, added level overall. I've only got two, but they work together really really well. Alex tells me that at some shows in Slovenia he's used 3 in an arc in front of the performer, which had the added advantage of giving her more horizontal coverage, and had more than enough power.

Like all the EONA ADRaudio gear I've used, these are very even off axis, with no noticeable change in frequency response all the way out to the limits of the coverage pattern, at which point it drops off rapidly. Ring out a mic in one place, or establish an artist's tone in one place, and it'll stay like that everywhere the monitor covers. I love this in the mains, too, since even if you're mixing off-axis you're hearing essentially the same thing everyone else does. Alex says this is partly due to using the highest quality drivers he can get his hands on, but also due to the time he spends manipulating the phase relationship of the two drivers. I've measured all the boxes and they're about as good as it gets in terms of both frequency and phase flatness... I trust them to go up and not need any adjustment unless the room I'm in has some serious issues.


Phew... this is getting really long, I'm going to finish up right after this so you guys can get to dinner. Thanks for sticking with me this far.

Last but not least is a line driver and sub crossover that Alex built for my rig and will soon be available for purchase. It's basically a master volume control plus +/- 6dB adjustments on the outputs for L, R, and sub (which can be summed mono from the L&R feed or aux fed from an external input). Each output has a relay mute, signal/clip indication, and a separate light that indicates box limiter activity. The subwoofer additionally has a polarity reverse and a 70hz LPF.

Here's a photo of that, front and back:
http://www.campuspa.com/images/eonaadraudio/index-Thumbnails/32.jpghttp://www.campuspa.com/images/eonaadraudio/index-Thumbnails/33.jpg

Anyway, it's a nice 1RU solution so you don't have to carry around a bunch of DSP for crossing over your mains. That DSP below is my monitor EQ for feedback cuts. What it's most valuable for is as a line driver... if you're pushing 300' of copper, this box makes a big difference, especially in the high end, which is one of my most favorite aspects of the U103s... it would be a shame to lose it because of some silly snake.


So that's about it! I've put a lot of miles on these speakers, for everything from choirs to jazz to rock for anywhere from 150 to 800 people, indoors and out. It's rained, it's been dusty, the power has been questionable, they've run for hours hard up against their limiters. There's not much more I can subject them to! Most importantly, they took it all without flinching and they sound the same as they did the day I opened the box. I hope everyone else likes them as much as I do, if you'd like to play with my rig please let me know and we'll work something out.

For your information, MSRP on these speakers is as follows:
U103: 3,080 euros ($3,850)
ATA118: 2,650 euros ($3,325)
M1225: 2,875 euros ($3,600)
Those prices are MSRP, so street is lower depending on how many you're buying and how much your dealer wants to keep Wink

Until there's a dealer network in the US, I'm probably the best contact for information. Call, email, or PM me any time. Of course, someone always answers the phone in Slovenia too, but that may be an expensive phone call if you're not in that part of the world anyway.

That U103 looks like another good reason not to get hung up on what diameter the LF driver is. Excellent LF extension on box. Monster horn for good lower freq contribution... I'm sure it's a fine box. With its 60 pound weight I know I could lift it onto a tripod alone which is something I can't do with a Yorkville U15P.

It's pretty cool when you can get your own "autograph model" system integrator.

I also really like the "it fits in my car" shots.  And I bet it all sounds better than what I regularly stuff into the Accord.

Probably costs more though Wink.

I'd really like to hear a comparison between the U103 and the "similarly priced" Meyer UPJ1.  It looks like the  the Slovenian box  has better low end potential than it's Berkeley born brother.

Very nice looking stuff, wish I could here them.  I'm not a big fan of all metal fronts due to wear & tear, but they sure do look nice.

And does the box actually sound good down to 70hz?  Or is it more along the lines of a normal 10"/12" box that seems to roll off into nothing after 90hz?

...a 1.4" exit 75x55 degree rotatable horn.

Bennett, did you rotate the horn?  The horn is actually a B&C ME90, and is stated to be a 80x60, but 75x55 is probably more realistic.  Anyway, I had a discussion a few years back with someone from B&C about the orientation of this horn.  I was told that the 80 degree horizontal plane is actually the curved sides of the bell.  With that said, your U103 is actually working in 60H by 80V mode.

Did you do any basic polar testing, or notice they were performing slightly narrow?

I measured them all the way down to 70, and they combine smoothly with the subs that cross out at 70, so it appears they actually go that low.

I've only measured them on axis, but I've been putting them up like they were 75 degrees and then walking the pattern and getting the results I expected, I'd be surprised if they weren't. I haven't rotated the horn or used the box on its side yet, though.

Well, wait, I've got one right here... I just laid one on its side, ran some HF program through it, and walked around. Seems to be doing what it says, very tight vertical control.

Horn actually IS B&C ME90 stated to be 80x60 degrees. Our measurements lead us to specify coverage data a bit narrower (75x55) because it is indeed more realistic. The actual difference is very small, but anyway...

"disfraction slot" at the throat of the horn must be oriented vertically, to achieve 75 degrees (wider) horizontal dispersion, so Bennett's boxes (ones on pictures) are 75H x 55V.

On the B&C web site photo "strongly" suggests otherwise. I never observed that photo so close up until today.

index.php/fa/6277/0/

(RCF horn : picture for reference only: wide horizontal x narrow vertical)...thanks John

Narrower exit in horizontal plane forces HF energy to "follow" horns sides and not to detach from them at higher frequencies.

On vertical plane however radiation angle needed at higher frequencies is smaller so so called "piston" effect doesn't affect coverage (that much !?!?)

Interesting.  FWIW, you can clearly see that the horn in Bennett's U103 is different than the picture you provided.  Your picture clearly shows a more common CD type diffraction slot, where the one in Bennett's U103 is slightly different than normal.  You can also tell that your horn is different by looking at the mounting flange.  The flange of course does not affect the pattern of the horn, I was just pointing it for the sake of showing that maybe your horn picture is from an earlier design.

What causes the HF to follow the sides of bell are the flat areas immediately adjacent to the throat hole, usually left & right of the hole and adjacent to the curved walls, just like your picture.  However, you can see in Bennett's U103 horn that the larger flat areas are positioned in the vertical along with the curved sides.  This is a 90 degree shift from normal horn geometry basics, and against B&Cs own recommendation.

Whatever though, the good thing is this horn is totally rotatable, so whatever works for you.

Hi Bennett,

Any chance you could share some of these measurements?
A “save as” of the delay finder after it makes an Impulse Response would be nice.

One up in the air on stands and one down on the ground as a stage monitor would be work.

Thanks.

Hi Alex,

I see from what Bennett writes that the single 18” sub woofer is ported.

There looks to be a slot f or a possible vent on the M 1225 coax monitor and a couple of holes under the woofer on the U103.
Are both of these ported then?

Since you are using an active xover did you consider going sealed?

John, if you look carefully you can see that the flats are still there, to the left and the right, they're just a little smoother and less obvious than with the older horn design.

I'll leave the rest of the technical questions to Alex.

All boxes are ported. I was exploring an idea of making M1225 at least sealed. However since diaphragm dissplacement in a box this small without port(s) would be out of B&C specs (of course after quite a bit of LF equalization needed to flatten low frequency response), I decided to go ported.

Where to port is of course another issue especially when designing "full range" box, such as M1225 or U103.

M1225 is ported almost an octave lower than its HPF (12dB/oct, Q=0,8 ) If ported higher, I would be able to achieve much more SPL in 80 to 120 Hz area at the price of rapidlly loosing everything bellow...Box is more transparent now and gives you good "feel" of bass. Basically this is small(ish) monitor and when you need more bass out of it at lower volumes (acoustic acts ??), you just pump it up ant it will react happyly.

All ports are very genereously dimensioned to reduce audibility at res. frequency....port on ATA118 is even "flared" or widened at its exit and this reduces noise produced by air "hitting" the grille. This widening caused some tuning tweaks, to remain desired port frequency, but sometimes trial and error is the only way....Antonne...I'm sure you know what I'm talking about Wink

Right on Curtis. I think I mentioned in one of my other posts, that the only way to achieve all desired specs is by using active circuitry....Ingemar Johanson did us all a great favor with LSPcad

Hi Alex,
I see you stuck to analog.
I have kept my eyes open for something digital that would work with LspCAD’s digital modeling. There is no way I am going to learn enough about digital to create from scratch.
So far I have found this-
http://www.quickfiltertech.com/html/qfilter_page.php?content _id=45

Check out the size of that chip!!!

http://www.quickfiltertech.com/html/demo.php

The problem is it is FIR. I need to go active below 500Hz and about then I start to hit serious latency. I need to find the same package in IIR.

In the end I thought maybe go active analog and add digital only for flat delay where I need it.
Just tossing some ideas about.

BTW I was surprised on how low you went with the B&C compression driver. The horn must support it quite low to make it stretch that far. Even with that I thought you would hit Xmax and shatter the diaphragm. 2nd order acoustic makes matters worse.

I’m getting away with it because the BMS drivers are a totally different design. I did not think conventional compression drivers would take it. At the least it should distort something fierce.  Wink

We tested HF drivers with 100Hz and 40Wrms and they lived. Because of drivers sensitivity you do not need "much" power in 500 to 1K region...however you need all the power you can get to maintain HF above say 6K ! HF "crispness" comes from high peak capabilities of the system...this is the reason you can not power HF driver with small amp with few tens of watts.

With normal acoustical programme HF peaks were in a region of five to ten times higher than LF peaks even knowing, that HF driver is trimmed down approx. 10dB to match LF drivers sensitivity.

In other words : at room level, where LF peak voltage goes to 5Vpeak, HF peak easily stretch in region of 50Vpeak ot higher. If you don't consider this, box looses its transparency and "realysm"

Well...we use only "page one" B&C drivers and over dimensioning paid off...using smaller drivers, that would suffer from problems you mentioned would result in completely different product....

Had a look at the ADR website, the 618hh sub sounds interesting with its different driver loading methods for a more cardioid response. My only question is how much does it cost, since its using 6 1000w 18" drivers... Shocked

I will put it like this : it is DE 900 TN - selected ... for consistent specs. I have to say, that those drivers are very consistent in their quality, but we still have to use only the best in our production.

Title: No Good Deed Goes Unpunished - A Novel By Dave Dermont
Post by: Dave Dermont on December 20, 2006, 10:50:20 am
I was given the use of some nice powered speakers free of charge for a month. They are ADRAudio speakers, and consist of a pair of single 18” subs, a pair of tops with a 10” woofer, and a pair of wedges. I also have the Bennett Prescott Signature Processor! This thing HAS to be good. I mean, both his first AND last names end in “tt”! I put said speakers into a small local nightclub, with the understanding that the club would pay me the whopping sum of $100.00 each night there was a show the system was used for me to come in and operate it. I would supply things like the mixer, snake, microphones, outboard gear, and cables from my inventory of personal gear to make a nice little in-house audio rig.  

I haul the speakers a couple hundred miles from the Troy, NY wedge fest to Olyphant, PA in my Jeep, and drop them off at the club. While dropping off the speakers, the club manager tells me that he can’t provide production for the bands anymore, and that the bands would have to pay to use the stuff. Fine, it’s not about the money. I just want to check out these speakers in a real world situation.

I show up at the next date when the club has a band booked, after loading my Jeep with a mixer, cables, microphones and stands, and all the other trimmings I need to do a proper show. When I get there, I am told that for tonight’s audio, the band “has it covered”. So, I hang out to see the level of production they bring in. What they bring in is a nice little PA for a folk duo in a coffee house. Too bad this is a hard rockin’ metal band. It’s not horrible, but it’s about what I expect as far as audio quality. A heavy band rockin’ hard, with a moaning in the background that suggests vocals.

I considered setting up the rig and doing the gig gratis, but was not feeling all that charitable right about then. Besides, some friends of mine were playing across town, so I decided to go check them out. The venue has a gig booked next week, and it’s a good one. I will wait ‘till then.

The day arrives when I will finally get a chance to hear these speakers, or so I thought. The band who put this show together, like a lot of bands, promotes on MySpace, so I log on to check out the buzz. I find a notice that says:

THE BAR IS SHUT DOWN AND THE SHOW HAS BEEN MOVED TO A DIFFERENT VENUE


I call the club manager’s two phone numbers, and both are disconnected. I call the club, and get an answering machine. I call the band, and they explain that the clubs landlord has shut off all the utilities to the building, making it impossible for them to do business. The band’s only contact with the club manager is through MySpace messages.

Now I have a pile of gear that does not belong to me locked inside a building, with no way to get inside, and the gear needs to be returned in a little over a week. The club’s phone is working, and I keep leaving messages. I send a MySpace message to the club’s (ex) manager. I call local law enforcement to see if they have emergency contact information. While talking to the chief of police, (The club is in a small town) he mentions a “For Rent” sign in the window of the place. I wait around until the next Monday morning and head out to the club. The “For Rent” sign is hand written in magic marker on a piece of loose leaf paper, but there is a phone number! I call the number, which is answered by the landlord who lives in New York. I explain my situation, and the landlord refers me to his local contact person, who says he will be right over. I get in and get the stuff. I feel MUCH better now.

A couple days after I get the stuff back, the (ex) club manager calls me on the phone when I am not at home. He leaves the info for the local contact guy and an apology. He is a good guy. I feel better about the world.

*review part*
In between the time I get the gear back and when I return it, I get to use one monitor wedge one time. Damn! I really wanted to put this wedge head-to-head with a Meyer UM-1P. Instead, I use it in place of a Behringer wedge. I hook then up through an unused aux on the house console with NO EQ at all. The singer loves it, and I am a hero. My legendary local rep (yeah, right) is enhanced.
*review part*

So there you have it. I get some really nice gear, but never get to use it. I do get to drive 500 miles and load and unload my Jeep full of gear four times for no reason. I also get a couple days of mental anguish where I get to wonder if the many thousands of dollars worth of gear I have been trusted with is even still in the last place I left it.

Ahhh… The glamour of it all. Aint that the REAL reason we do this?

This brings back lots of memories of doing sound for clubs back in my formative years. The only element missing in your novel is fire. As in: "no apparent cause but of suspicious origin" (a category that seems to plague R&R clubs and discos).

So, despite the hardships and frustration, you were perhaps lucky. I was lucky in that the only 2 times the system was firewood it was owned by the club. Other times, when it was rented (my gear) I had removed the system for other shows. It took me perhaps 4 episodes of ths nature befor I began to focus my efforts elsewhere when the vibe (evidence) indicated I should do so.

If you'd like to mess around with this rig, PM Jim Bowersox or myself and we'll work something out! I'd really like it to wander around the Maryland/Delaware/Pennsylvania area for a while.

I was just reading through this thread again and I see I totally failed to follow through on this. My apologies! As I am conveniently in Slovenia, I grabbed my measurement mic and got some basic traces indoors (it was raining) of the 103, U61, and M1225.

Bennett,

Will there be a demo rig in the Portland/Seattle oval anytime soon? I'd like to hear it, but don't really have means to play with it personally at this time. Even Bend, OR would work.

Caleb, I don't have anything heading out your way at the moment, I need to get a rig down into the TN/Florida area first, and then I'd like to run one around the midwest. I'd very much like to get you something, as soon as I can spare some equipment I will.


Bennett, both myself and Matt Jordan are with in spitting distance of each other here in Idaho.  We would appreciate um.... make that "LOVE" the chance to demo these little gems.

Hey Ales,

I think everyone is right here in this situation!  Smile

I was noticing the TF of what Bennett later identified to me as the monitor wedge, which WAS measured against a half-space boundary, and therefore was showing the boundary effects.  I scanned the curves very quickly, and that was the only one that caught my eye.

Post by: Danny Mullins on April 16, 2007, 10:16:59 pm
First off, a big thanks to Bennett for getting these boxes down south. And now for some first impressions.

1) Extremely portable. Went to pick them up from the shipping company in my Ford F-150 and rain was coming. I was able to break the pallet apart and fit one sub in the front passenger seat (with the arm rest up), one sub in the extended cab behind the one in front and the top boxes behind me in the extended cab. (Monitors are shipping separately so I didn't have to work them in) Really didn't expect to get all that in the cab of my truck.

2) Very solid built boxes.

3) Was able to hook up tonight and run some canned music through the system. The system integrator made set up very easy. I like the flexibiliy to be able to run an aux send into the subs for aux fed subs. (I am a very big fan of aux fed subs)Also selectable HPF & Polarity inverse buttons, very nice details in a simple setup.

4)Oh by the way, did I mention  the speakers ROCKED! Excellent level out of a small package, and clean even at high enough levels for the neighbors to be able to listen in. The tops and subs complement each very nicely when using the ASI 23. I am going to try them on my DriveRack also to see how that might work. I was a little sceptical about crossing at 70hz, I thought I might be losing something between 70 and 100, but so far it sounds like the tops can handle it down that low.

I ve got a couple of bands to give these a whirl on and will be getting back with more thoughts and comments. Also hope to have some pictures.

Make sure you try the subs coupled.  In the coupled configuration they will easily outrun the tops.

Also the ASI23 has no processing besides the 70Hz crossover and polarity inverter for the sub.  All the other processing (eq, crossover, and limiter) is in the speakers.  The ASI23 does give you volume control and some nice lights to know when your hitting the limiters.

Did a acoustic gig last night. One guitar (Takamine, though an EWI active DI) and two vocals (both on AKG 535's). Set up both U103's and one ATA118. Mixed with my other new favorite toy, my 01V96V2. Had a little less than 100 peoples in a room about 75' x 50'. The guitar sparkled. Very tight mids and crisp highs. Vocals were very clean and intelligible. I think I would have to try very hard to bring out the 'mud' in these speakers. I have not done any measurements but from what I have heard the tops really shine in the 3-4Khz and 80-150hz range. Excellent fidelity. I am looking forward to mixing a full band on these. Thanks for the tip on coupling, it was on my list of "to do" with these guys. By the way this was one of my easiest setups in a while, powered speakers and subs, 01V, mics and direct box. If I only had a nice powered monitor for the set up.....

I got a chance to mix on an Eona rig this weekend and I liked it quite a bit! I was mixing sidestage monitors for an outdoor festival and Bennett was kind enough to supply 4 of the 12" Eona wedges for the front 4 mixes, the single 18" sub for drum fill, and 2 of the u103's, one for drum fill top and one for cue. Board was a DDA CS8 and the only outboard processing was my DBX1231's and a Driverack 240 for the drumfill. We went ahead and set up mics prior to the bands arriving (Audix mics all around) and rang the wedges out. We assumed worst case scenario with EQ cuts and wanted to be sure we had plenty of gain before feedback. There was a good bit of cut going on up in the 4-6.3k region on the graphics and a few others here and there but we managed to get good levels for even the loudest of bands.

I ran pretty full mixes on each of the wedges and alot of everything through the drum fill and the wedges were barely breaking a sweat. Lots of compliments from the musicians about how well they could hear on stage. The drum fill was slamming so hard that the top box almost shook off the top! I had to strap it down. The power and quality of the wedges made it easy for a rookie Monitor engineer to get things pretty solid on stage.

I especially liked the 12" wedge and the single 18" sub. They are both incredibly light for their size and very powerful. Now where can I get some free samples Very Happy

I came home Wednesday evening to find the UPS guy had left me two large packages. My monitors had arrived just in time for a Thursday night gig I had. I was providing PA for a Fund raising banquet for the local FCA (Fellowship of Christian Athletes). Venue was the gym at our local community college, and would be covering about 250 - 300 peoples. Set up the 2 U103 mains on stick to each side and one ATA118 sub center stage, then put out the two M1225 monitors at each corner of the stage for the band. The band consisted of two vocalist, two acoustic guitars, bass, & Djembe (spelling?), so I didn't have to push the monitors very hard as this was a very laid back gig.

index.php/fa/9153/0/

The band immediately commented on the clarity of the monitors. I really liked the combination power/signal cables Bennett sent with the monitors. this is the first time I have had much experience with the powercon connections and have found them awesome. This was a talented bunch of teenagers with really great attitude. That in combination with the ADRaudio rig made this gig a lot of fun to do. I ran my drive rack with the rig this trip out and used ASI 23 as a master volume for the individual sends.

Hi All

Sorry Danny, for a little thread hi-jack, but Bennetts original thread has become a wee bit long...

In the first ADR thread, I promised I'd post my comparison between my 'normal' Turbosound TQ445DP/TQ425DP setup and the ADR U103/ATA118 (or ATA218) combo - here it is:  

First of all: If any of you Danish Labsters are interested in a demo of these speakers, just get in touch. contact info can be found at www.onstage-online.dk

Second: Thanks to Ales and Franci for providing the demo-rig and for stellar support.

First, I've been really pleased with the Q-light speakers. I've never really liked Turbosound, but these are actually very good speakers and extremely versatile. They are worth comparing to the U103 for two reasons: 1) they cost the same, almost to the penny, and 2) they try to solve the same problems and come up with very different solutions. You can see the details at Turbos and ADR's homepages, but the short version is that the Turbo TQ445DP is a bi-amp class D, 3-way design (12"coax + 6" hornloaded mid) with 96/24 DSP, while the U103's are a bi-amp ICE Power, two-way (10"+1,4")all analog design.

These two systems a virtually night and day. The Turbos are insanely loud - nothing can touch them in terms of dB's per cubic meter (they are almost the same size as the U103, only slightly wider of course). We proved this later on after a few beers, when we came up with the brilliant idea of putting all the subs together (1x ATA118, 1x ATA218 and one Turbo TQ425DP pr side) and putting one TQ445DP on top - and they very nearly kept up! We measured 124dB's at 6 meters.....

Both systems try to tackle excellent vocal reproduction, The Turbos with the 6" inch driver, The ADR's with a very warm focused frequency response and even dispersion. The techs there unanimously decided that for rock'n'roll, the TQ445 would be the best bet, but for everything else we would most likely prefer the U103. The dispersion is a major problem with the 445, due to the odd design. I did a cosumer-fair last month with a U103/ATA218 combo and both us and the visiting techs were amazed at the uniformity of the sound image, you could walk the entire hall (1000 capacity when empty) and as long as you stayed within the coverage area, all that changed was essentially the SPL. With the Turbos we would have gotten good results too, but we would also have had to fight low mid build-ups at the center and poor, 'jumping' coverage in the outer parts of the audience area. With the ADR's we got better sound with less effort.

In short: The TQ445 was built to be a do-it-all box, and by choosing the odd-ball 3-way design, heavy DSP capacity was needed. The end result is a really good speaker with very good intelligibility (I hate that word) and unsurpassed SPL capacity, but with dispersion/phase issues and limited arrayability.

The ADR U103 was designed with pretty much the same goal, but with a very different approach: emphasis is on good solid engineering with a KISS 2-way design with very high quality drivers and a big, wide dispersion horn. Innovation is there in form of ICE powerpacks and 'retro' analog electronics. The result is essentially a much more neutral speaker, with extremely even dispersion pattern. You could almost describe the sonic difference as the Turbos being 'digital' and the ADR's being 'tube-like'. The trade-off is lower SPL capacity and shorter throw. Arrayability was not tested, but I think it is fair to say that the U103 would be the winner in that category.

The (prototype) U103 we got had two shortcomings:
1) the noise floor. They are really noisy, enough so to make them attract negative attension at, say, theatre gigs. Ales has told that this is being fixed by changing to a better quality op-amp.

2) If you don't use the ASI integrator, be ABSOLUTELY sure that your source has a balanced output, otherwise you will nothing but hum. This is pro-level gear, sure, but it is not particular combat audio friendly. With the ASI, no problem.

Actually, the U103 is hard to demo. As I mentioned, they lack that LTL smiley-face sound most techs expect from their PA's, but in real life usage they provide a blank canvas that is extremely easy to mix on: You have to try very hard to make them sound bad, and with a minimum of effort they will sound fantastic.

The Turbo and ADR subs are also very different beasts. The ADR's goes a LOT deeper than the TQ425DP, almost 3/4 octave according to the spec sheets, On the other hand the Turbos have more clarity in the 60 -100 Hz range and significantly more punch, pretty much what you'd expect from 18" subs vs. 15" sub. We got killer results by combining them, by the way, making us guess that an ATA412 + ATA218 combo would sound pretty spectacular.... The cardioid pattern of the ATA218 has been a plus in every application so far! Ales claims an 18dB difference between front and rear. I'put that figure somewhat lower, but still impressive and useful - and done without DSP!

The ADR's really comes through when pushed: The Turbo subs simply looses dynamic range and starts to rumble in a not particularly pleasing manner (they are bloody loud, though), The ADR's limiters acts more like a slow-attack compressor, so that, for instance, a kick drum will remain a kick drum even at very high SPL's and the box flashing brightly. Very well done indeed. I would like to have a bit more clarity, as they tend to rumble a bit, but the LF extension and dynamic range are really really impressive, probably the best I've heard in any PA sub.

One thing we've noticed over time is that these boxes, both tops and subs, fare much better with live material than canned music -  luckily Smile :

The warm 'anti-PA' character of the U103 could lead you think that it could become muddy and unclear 'in real life'. I deliberately tried it out with some jazz vocals using KMS105 mics, thinking that this might make any problems in the low mids fairly apparent. With a flat channelstrip-eq and no outboard, apart from the ASI23, everything was exactly as it should be: warm, clear and transparent. Sometimes it's easy being the sound guy Smile

I think that was it....

Title: Eona M1225 review
Post by: Jamie Taylor on May 21, 2007, 07:26:31 am
Alrighty.

After going out on a few small tours with another Lab regular (Dylan Shepherd) using the Eona U103's and ATA 118'sand the M1225's, I got the chance to mix monitors on them at a local radio station gig, with mid-large local band Thirsty Merc.

The set up was your regular rock band set up, with Bass/vocals on stage left, Vocals/guitar/keys and guitar/vocals on stage right.  I was using single M1225's for the frontline monitors, with a U103 and a ATA118 for drumfill.  I had two sidefill monitors, but these were AT Showstacks.

My first impression of these monitors is how incredibly light they are.  Compared to my favourite monitors to work with (the Clair 12AM's) they're practically feathers.

When I eventually got to tune them, they were remarkably flat...from memory I had to take about 2db out of about 4 frequencies for the m1225's...and that gave me heaps of headroom for the band, who liked it loud (they did start feeding when the support act, a bunch of dancing girls, started pointing wireless 58's into them....but that was my oversight).

I'd still love to really put some volume throught them (with a local metal band)...but for the size and the weight, they're great.

Pro's:

- light, really light.
- quite flat.

Con's:

- expensive, but you really get for what you pay for (and though it would cost about the same for an amp and crossover, you can use them for other boxes)
- not as loud as other wedges.
- Seem to scratch easily.

Overall, they're great boxes, and are definetly on my 'to watch' list.  It would be interesting to hear the larger line arrays.

And on another note, on one of the shows we did, we had no stands for some Mac's, so to our disgust, we had to make the most expensive light stand ever:

Hey folks,

Couple of quick things.  These look like some really good products.  
However I do not see anything mentioned on a PIN1 test.  Is Pin one connected to the chasi?   Also Im assuming a universal power supply.  Will they work over seas?  

That small coax monitor looks interesting there are not many coax monitors that are powered availible in the market that I know of.

The only thing I see missing is a place to stick a leg from a tripod stand like the rat wedge which is really rad.

The SMAART print screens look good, however coherence isnt shown so  and im not sure really how this measurement was taken.  You could also use a time window measurement.

While were talking about measurements and monitors as any one ever done an alignment adding delay to the monitors to have a phase cancellation at the microphone I think a set up like attached might work.

Heya Josh, thanks for chiming in. To answer your questions (except for the monitor thing, which I have never done, but might be interesting at LF)...

Pin 1 is lifted at audio frequencies, grounded at radio frequencies. As you can see from Erik's experience, this works well in most situations, but not all. In order to find a better solution, we've brought in one of the best in the business when it comes to audio shielding and grounding, and we're working through a new method of dealing with the way our products interface at audio and radio frequencies that should make them nearly bulletproof in a wide range of situations.

The power supplies are not universal. On speakers with switching power supplies (like the M 1225 and ATA 118) it is possible for a user who is comfortable with electronics to switch the position of one fuse and adjust between 120 and 240 volt operation. On products with conventional power supplies (like the U 103) it is possible to switch mains voltages by swapping a few wires on the input side of the mains transformer. In either case, protection circuitry exists to ensure that if the wrong voltage is supplied the loudspeaker handles it gracefully (read: does not destroy itself). We are happy to adjust speaker input voltage for users at our factory, or they can have one of our distributors do it, or we can walk them through it over the phone.

As for having a stand mount hole, we decided early on not to try and make this a "one size fits all" box, with flyware and stand mount, etc. Our experiences with speakers like that in the past have been mediocre, and that format is often abused. We don't want to see the M 1225 used as mains or sidefills, the speaker relies upon half-space loading to maintain even bass response down to the stated 52Hz, and its response has been tuned for near field use. I have used them as front fills by standing them up on an edge, and others have gotten some pattern adjustment by sticking 2x4s under the front or back, and that's all well and good. For mains or sidefills, however, we make the U103 and other speakers more powerful that are designed for farther throw and higher output.

As for the Smaart printouts, we took those measurements indoors in an approximately 30'x15'x8' concrete-walled room, with the U103 on a tripod and the M1225 on the floor. The mic was on a stand at my ear height (let's call it 5'6") and in the case of the U103 about 2 meters away. Nothing fancy at all about this setup... we were going to do better measurements outdoors but it started raining and I had a plane to catch.

Post by: Langston Holland on June 13, 2007, 11:14:36 pm
Well boys and girls, I just learned two things:

1. Slovenia really isn't a make-believe place where elves make cookies in trees.
2. Some of the loudest and best sounding loudspeakers for their size come from elves that live in trees.

I'm the current holder of two U103HH tops, AT118HH subs, M1225HH wedges, a little single rack space mixer/controller to aid the demo users and all the necessary cabling to make it work. Each loudspeaker is beautifully executed, self-amplified and glorious analog. Whoever put this stuff together is a passionate to borderline OCD craftsman.

For those that got their fur up with the "glorious analog" comment, I've yet to hear a digital audio component that didn't to some degree mess up the sound of something that went through it... except... (1) Benchmark D/A converters, (2) the Dolby Lake processor, and (3) whatever that weird stuff is inside my EAW NT29 boxes - so deal with it! Shame on you traitors and cowards who have sold out the beauty of what first attracted you to this sport at the altar of convenience! Oh, the joy of my comfortable little padded white room with those nice men that always feed me when I ring the bell.

Oh yeah, the loudspeakers...

My business is such that I rarely do events with fewer than 500 folks anymore, thus the 10" two-way U103's and single 18" ATA118 subs are not on my hot list to buy. Nevertheless, the day after I picked up the demo speakers, a last minute fancy club gig in Destin FL came up. The second surprise was that the band was quite good. The third surprise was that the band's manager was in charge of a large outdoor event coming up in a couple of months and she was so impressed with the sound that I got the gig - roof, stage, flown speakers, etc.

I want the wedges

What I was really interested in were the active wedges, I've got a dozen 12" Radian Microwedges that I have pleased a whole lot of muso's with - they sound quite good and go loud as stink with their 2" compression drivers. They've also proven very tough, though I do few screamo shows. :) They do have a positive/negative aspect to them in that they have a very narrow pattern where the highs are "right there". On the upside, it forces the muso to live right on top of the wedge to hear things properly thus giving me the ability to keep levels within reason on the stage. On the downside, it forces the muso to live right on top of the wedge to hear things properly thus giving the guy little room to move. The EONA's with their 1.4" compression driver have much broader and smoother HF coverage and give the muso a reasonable amount of wiggle room. Actually, I think the coverage angle of the M1225 is just about a perfect balance. The Radian specs a 90 degree conical coverage while the EONA specs 60. Go figure.

I wasn't in the market for wedges, I was happy. Now I'm unhappy. The M1225's sound substantially better than my best efforts at biamplifying the Radian's. They also weigh about 18lb less including their internal processing and amp. They also are within spittin' distance of the same usable maximum SPL. Still, truth be told, the Radian's are way sexier than the EONA's. I noticed, _I mean I heard_ that in the basement Alex attempted to make up for this with a picture of a young lady donning an EONA shirt. Based on my experience around here, I'd say Alex is innocent and Bennett is guilty until proven guilty.

Another thing I love about the active EONA stuff - no stupid switches (SS) or potentiometers. Who in the world can keep up with all that on a busy stage? IOW, why does my favorite DI, the Radial JDI, have all those SS within grasp of the weirdoes on stage that only experience positive reinforcement for destroying things? I put gaff tape over the SS on my NT29's. And how much did those things cost? Oh yes, I did shoot out the M1225's against the digital heretic's (aka horndawg) NT29 and the latter sounded better. While both have very transparent limiters, the EAW implementation is inaudible to me. The NT29 sounds so good that it makes me laugh every time I hear it. It's that good - like a Danley SH50. Those two boxes are the best I've ever heard in live sound. Nevertheless, the NT29 makes a poor choice for a stage wedge primarily because of its horn layout. Walk off to the side of the woofer and it too quickly gets dark, walk off to the other side and it too quickly gets bright. Oh, but in the middle... Plus it's too expensive to waste on a muso. I dearly hope this isn't the case for the M1225... Bennett!! :)

Measurements

I doubt the little mixer/controller gizmo is part of what you get with the tops and subs, but Alex likely just wanted to make things easier on folks so they wouldn't have to add their own processor to deal with the subs. Nevertheless, I measured the thing to figure it out. It appears to me that though it indicates limiting levels, it does not do any processing besides offering a 70Hz/12dB LP filter with a polarity inversion option for the subs. All the real processing seems to be included inside the loudspeakers. Below are measurements of the U103 and ATA118 outputs without the LP filter (white) and the ATA118 output with the LP filter both in (blue) and out (cyan) of polarity:

With the LP engaged (purple), the sub is -6dB at 105Hz. This is generally a bit high for my taste, but seems to work pretty well with the U103 tops. I'd probably use a 4th order LR low pass filter on the sub as that seems to be the most forgiving slope in this application given our penchant for ye 'ol haystack: (edit: the 2nd order electrical filter combined with the 2nd order acoustic rolloff of the sub achieves the 4th order response I think best, but I'd still prefer the -6dB point down to 90Hz or so.)

I did ground plane measurements on the tops instead of the PV on a stick method to keep things simple. The downside to this is that the LF is boosted a bit from the response they'll exhibit on a tripod. Still, these things measure like they sound, absolutely wonderful. This is one of the best I've ever seen with a nicely behaved phase curve:

http://www.soundscapes-info.com/pub/PSW/EONAU103Top.png

The M1225 wedge is also wonderful, not as polished at the top because of the latter's ability to use a real horn instead of a hole through a woofer pretending to be a horn (right Curtis?). Still, it sounds great and is amazing how loud you have to make it before its red limiting LED comes on. There are two measurements here, in standard wedge position (purple), and in a ground plane setup (white) to avoid the ground bounce cancellation you see between 125Hz and 400Hz. You can see the designer accounted for cancellation with a bit of boost in this region to offset it. This is a good compromise and the end result is a balanced LF output to the muso. I've seen much more of this "wedge ground-bounce cancellation" with other designs and none that I can remember with an offset boost to reduce its depth:

Here is the wedge position trace by itself for clarity. This curve sounds great and the dip between 4kHz and 8kHz is likely to offset the typical vocal mic presence boost in this region to result in higher gain before feedback:

Measurement Setups

The real version of Smaart (v5.4) with a real computer (MacBook Pro) with a D-Audio sound device and a B&K 4007 omni microphone. I measured at a sample rate of 44.1k and 24 bits using a red sweep stimulus for the subs and pink sweep for the tops and wedges. FPPO is for girls. I increased stimuli (love that word) levels until limiting engaged and then backed off 6dB.

You madman! That's quite the review... Very informative to see the Smaart screenshots. I'd be curious to compare a screenshot of the M1225 with the limit light getting tickled to your screenshot of performance 6dB below limiting. How much added coloration?

Uh oh, I just noticed the PowerCons and the made the connection that I don't have any on the distro. Does the demo rig come with the proper adapters or do I need to get out the screwdriver and multimeter?

I'm just gonna toss this one out there for possible future EONA designs. My favorite ADR box of the bunch is the single 18" sub, it's a real asskicker. A good application of it is as a drum fill sub, and here is where my idea for this suggestion was inspired. The way we have been running the sub as a drum fill is up on one end with the "handle" side to the floor. Perhaps it would be good to put some small feet on one of the handle sides of the box so the (very durable) coating doesn't get to messed up when running it in this configuration and having musos and stagehands slide it around the stage (instead of picking it up, it's what, like 65 pounds?). Might also make it easier to slip a handtruck under it too when it is on end.

Hey Tom, I'll talk to Ales about that. Sounds like a good plan.

BTW, the sub is actually 99lbs.

Looks like the sub should do a bit of workin' out too - it's gained 3.5lb. :)

You should weigh it without its little cover!

Very Happy

P.S. the specs online say it should weigh about 108 lbs.

Langston, or Bennett for that matter

Is that the "factory" cover from EONA ADRaudio or something made up locally?

Cheers,
Lee

45Kg, 49Kg, let's split the difference Wink Seems I have an out of date spec sheet stored locally.

Lee, that's a cover that I have made by Under Cover NYC. They have the specs on file but you can order them directly from us as well. At some point we'll have them in quantity, with cute little EONA ADRaudio tags, but until then they're a one off item. Happy to furnish drawings for anyone who'd like to have covers made elsewhere, as well.

The covers come in handy if you're moving the gear a lot in non-conventional ways... Here's Jim Bowersox hauling a whole rig around at a Redskins game:

What you mean "non-conventional"?

Thats the way I move gear into MOST of my gigs.
Hotel ballrooms, college auditoriums and every morning  the Downtown Berkeley Jazz Festival down the block of Shattuck Avenue between the Jazzschool and the Berkeley BART Station Plaza.

Loading docks and ramps are for the "varsity" players Smile.

I recently had the pleasure of getting a demo pair of the ADR Audio U103 10" 2 way Active Loudspeakers. After learning cost i was spectacle that this would be on par with other boxes this size and $$. I used them as front fills for a 2500 person event where my line array was flown and needed so inner coverage close to the stage.

I was really blown away at what these little boxes could do. I had time to test them prior to the night beginning by themselves and was astonished how well they did down below 100hz! They were really strong down to 80hz and lower - they didnt really start to roll off till just below 70hz. on top of that they were LOUD! About 102db at 65' and the limiter lights were not even flickering. They also sounded (to my ears) sonically remarkable. Almost reference quality.

A few weeks later i put them up against several other small boxes (yorkivlle NX55P, EF500P, Mackie SRM450, JBL PRX612M and they were just miles above in performance... louder, soniclly much better, low frequency response was unmatched.

I wish we could afford a half dozen of these and i had the opportunity to try out the subs...

I've only had the opportunity to hear the Eona products at 2007 NYC sub shootout, and was very favorably impressed with what came out of those little boxes (as well as the 618).

Ales and crew know the "secret sauce" and how to inject it into their systems.  They are comparable to Meyer and other high end systems and are priced accordingly.

Have fun, good sound.

Thank you, Dan, for your nice words.

Being a FOX mixer and loudspeaker designer in one person helps.
