Title: DB Technologies VS Aero 8A
Post by: Mauricio Velez on January 09, 2014, 03:59:48 PM
Gentleman,

I currently own a SRX system and a hybrid Mackie SWA1501 with a QSC K12, I am happy with both but the SRX series is discontinued and I want to go to a non fixed angle line array system for bigger shows, with the SRX for regional Mexican, Jewish orthodox and small festivals, I am Ok, but when I do bands close to 800 people or bigger festivals, the SRX system is small and not well received and also discontinued.  I do not want to go STX.
I was checking the DB technologies T4's as other local companies use it but I was offered a very good deal with DAS aero 8A, the rep says the box is superior to the T4 and the price is way better at least for me. The other issue I have is that I am not aware of anyone using the aero8a in Atlanta, so how I am going to rent more when need it? both boxes are easy to ground stack and not heavy and can be complemented with a bigger box later on.
Another goal is to have all my speakers in the future for the same brand.  Please let me know if I left any critical information out and I will be glad to provide it.

Cordially
Mauricio

What SRX boxes do you run?

Both the T4 and the Aero 8A are (on paper atleast) a big step back in output, whether that matters depends on the area you need to cover and how big of a hang you would deploy.

Properly powered, SRX gets pretty dang loud.

I own 4 SRX 728 and 2 SRX 725, Powered by XTI, being  trying to buy 2 more 725 for over 6 months. I know that about the XTI and I am not planning on sell them yet, but my next step includes a line array.

I haven't mixed on an Aero 8 rig so I can't make a direct comparison but we own 16 T4.  We're also heavily invested in JBL VerTec 4887, 4889 and 4880 subs.  It's tough competition.

As much as I love the T4 for what it is and that it paid for itself in less than 8 months, by -4 dB or so it's not in the same class as the VerTec 4887 (which I think is the minimum JBL line array comparison to the SRX725).  In fairness, the T4 rig is also -4db$ in price and -3dB# in weight (thanks, Jay) compared to 4887.  If you can live with lower total SPL the T4 can be very nice.

What a line array can give you is better uniformity of coverage, front to back, IF you have the means to fly it and dedication to learn and use the prediction tools provided.  If you're thinking about ground stacking on subs, please give up the idea of a "line" array and buy one of the other fine conventional "point source" speaker systems if you can't find another pair of 725s.

We have an annual charity fashion show & auction that I originally designed with VerTec 4887.  This year I used the T4 rig.  The audience area is roughly 110' wide x 145' deep, seated audience.  The DJ pushed the rig hard in the fashion show and I really think we ran out of rig about the time the client ran out of SPL tolerance, but the 4887 rig would be coasting.  The 140' throw seems to be past the limit for the line length 8 T4 boxes makes up.

What I've learned about line arrays:  you must fly them - yes really - and anyone who tells you differently does not listen with their ears; you must learn the prediction software and use it every time you are in a new venue or changing deployment from a previous visit; you need to learn if the prediction software accurately represents actual speaker system performance and if not, in what ways; and if it's not loud enough adding more boxes will not significantly increase the SPL (and what gains you make will come with a sacrifice in clarity), you need a bigger, louder model.

Hi Tim,

The 4887 has 2 x 8” + 4 x 4” + 2 x 1” and is rated at 1000 watts. In comparison the T4 has 1 x 8” + 1 x 6” + 2 x 1” and is rated at 410 watts, and weighs half as much; so I’m not surprised the JBL will out run them.

As you said, for what they are the T4s are great and provide an excellent ROI.  In comparison for a little more money the new T8s sound much better and go about 4dBm louder.
 
I suspect that as Mauricio was advised, Aero 8s may sound better than the T4s, but in comparison to the T8s it may be a different story.
 
The advantage with T8s is that they will integrate perfectly with T12s if you need to expand. While T4s can also be used with T12s they don’t sound as good and need to be delayed 0.3ms relative the T12s.

If you don’t need to meet rider specifications, the T8/T12 is a great cost effective combination that can be used in so many applications. It doesn’t sound as good as boxes like Turbosound's Flex Array or d&b's V-series, but it does sound as good, if not better than many of the older respected name-brand / rider boxes.

A T12/T8 rig if needed can be scaled up to cover 5000 or more people.

Finally I ended buying 6 T4's and 2 Fly bars,  I did my first comparative test with the SRX rig.
With 2 SRX 725 powered by 1  XTI 6000 in stereo and 2 SRX728S powered by 1 XTI 4000 bridged each, I normally have to reduce the XTI 6000 of the mid/his to 8 to balance the hi/sub ratio.
With 3 T4's per side over 1 SRX728S  powered by the XTI4000, the Sub was not able to keep up at all. For my 6 T4's I'm going to have to carry the 4 SRX728S I own, until I buy the S20's. What impressed me the most is the way they really work together, 1 box alone sounds barely OK, 2 boxes sound way better, 3 boxes together really sound great.
Thanks to  John from Trinity productions for a great sale,  I choose him because the reviews he wrote in this Forum and in Youtube. Disclaimer: I work for Solaris but we are not DB Technologies dealers.

Mauricio congratulations on the new purchase.

My inquiring mind whats to know why when people consider db t4 or t8 they do not consider RCF HDL20a?  I understand the RCF is 2 way and db 3 way. On paper the RCF appears to get much louder.  Has anyone done a side by side of these speakers?

Thanks

My reason was cross renting, same reason I did not choose DAS, I can rent extra T4 and T12 with several companies in Atlanta.

I spoke a little soon about the T4's, doing further comparison with the SRX725.  Using SRX728S for both, is not that the T4's are louder, is that the SRX725 help the subs,  so you run out of bass sooner with the T4's, all my tests have been ground stacked.(http://)
My Question to Tim and all: Side by side the SRX combo sounds way better that the SRX/T4 combo (SRX Is a little louder but the there is a huge difference in the highs) The T4 in any EQ setting sound dull in comparasion to the SRX. Is this because I am ground stacking?, Is this the way Line arrays sound to avoid excess highs and mids when you use a lot of them? or is just a case that you get what you paid for?
Thank you for all your inputs.

You need to get the array over the heads of your audience, otherwise people absorb the HF.  Running the array at 0° box angle also creates interaction issues that cause fidelity problems (comb filtering).  As Tim said above, you need to fly the array and use the calculator to set the system up for your room to get anywhere close to the best possible fidelity.

That, and you need to set the EQ preset switch on the back of the speakers to be consistent with the splay angles between units.  And for ground stacking, all bets are off.  This is exactly why I don't recommend "dash arrays" especially ground stacked.  I do both, BTW, but how I achieve the results I do is work done for hire and not discloseable.

That said, I highly encourage Mauricio to experiment and to really take the time to learn and work with the newest version of DVA Composer prediction software.  That's mostly what I did, it just took some time both in the shop and listening at gigs.  I just can't say what I ended up doing.

Also, in the near field a speaker like the SRX will always sound better.  Nature of the "line" beast.

After 2 months of trying to like the T4's, I'm absolutely disappointed with DB technologies. I know I am not using the box 100% right by ground stacking them, but the box is weak! With 3 per side at a cost of over $10,000 without subs, you can barely cover 200 people a total length of 15 meters, when using 2 SRX 725 will blow their heads off. How can flying them make for more SPL??  Plus the bass runs out because the box doesn't help at all. Just to clarify- people were not blocking the boxes, plenty of space and still super soft. I love my K12s, I love my Yamahas club series, in its' time I loved my Mackies, but not these speakers. Are my ears lying?

Faced with the choice of DAS Aero 8a, RCF and DB Technologies, we ended up going with the Aero 8. It just had better presence (once the "Spanish" EQ was tamed)

So far, it goes plenty loud enough for the applications we got it for:

playback events up to 2500 people
rock and dance events up to 1000 people
theatre up to 3000 people

So far we have used it ground stacked in a dash array, as well as 2 x tops on a pole of 1 x sub, single boxes as fills and of course flown in large hangs.

The secret has been to use a "Front End" system processor to align the system and tune it for each configuration - single, pairs and threes of boxes require quite a lot of low mid EQ applied as well as altering the cutoff filter of the subs to go with them. I would personally like more access to the dsp in the boxes and a flatter "out of the box" tuning.

Our stock is:
24 x Aero 8a
6 x LX212 (flying sub)
4 x LX215
4 x LX218
2 x I beams which allow the LX212 to be flown behind the Aero 8s;

We are looking to expand by adding a further 2 x LX215 and LX218 to the system in the near future.

A firm an hours drive away has 8 more Aero 8s and 24 Aero 12s, so cross rental is possible.

I think you must be doing something wrong.  From the pictured you posted it looks like you are not using dB Technologies subs (?), if that’s the case how do you time / phase align them to the T4s.

This could be why you are saying “Plus the bass runs out because the box doesn't help at all” perhaps you have some cancelation at the crossover point.

You also said “The T4 in any EQ setting sound dull in comparison to the SRX” … I found the T4’s if anything bright. I also found the T4’s threw well and were quite loud.  In comparison to a point source boxes they “will not take your head off” up close, but setup correctly (and you really need 4 or more a side) the SPL will be much more even over the venue.

If you want serious performance however, you really need the T12’s and or T8’s.

We considered pretty much every compact "proper" line array easily available in the UK including FBT etc.

We got offered an incredible price on the DAS - so good that even if it wasn't what we were looking for we would still take it. As it happens, we are extremely impressed.

I have already used my 6 T4's with the 2 S30 subs 4 different times and I am already in love with them.  The big mistake I was doing was that I was not using a crossover and I was sending full signal to the T4's plus I suspect that the T4's and the SRX728s where not playing well together (I just assume).

The subs are fantastic, very deep, punchy and easy to handle, the have something call "In rush current" that when you plug them they immediately fill the capacitors and if you are plugged in a weak circuit they will trip it right there and not in the peak of the gig with the dance floor full, great for me that I do not carry a distro.  Also not carrying amps or speakers cables makes the setup faster, lighter and cleaner. Last week we try to bring the LEDs to RED and I was hitting 117 DBs at 15 meters before we have to lower the volume in an indoor party and my DJ who I always have to demand to lower the volume was asking me if we can trim the bass a little.  My next purchase as soon as I sell my SRX system is 2 more T4's and then another 2 more S30.

Pretty much the general rule with " line array " speakers is that you must have at a minimum, four boxes to even acquire line array benefits, The level of sonic control is directly proportionate to it's length.  From my experience, 4 boxes won't cut it; ever....... I like at least 6 per side. By this point in time you start to reach a level of control that is on line with what is needed to acquire the desired and expected results. If I get spec'd for 4 boxes per side I cringe and certainly lean hard for more. Having worked with Meyer, D&B, JBL and some others, It seems that proper deployment is the absolute core to getting expected results.

I think you missunderstood that part. A high inrush means the amp draws a lot of current when it is switched on. This has nothing to do with how the speaker behaves while the show is playing. It still could trip your breakers. Actually it is the opposite of what you want. Good products have a inrush current LIMITER which will stop the amp from drawing too much current on power up, so the breaker won't trip. Better products have this limiter still working while the music plays, so no tripping when the amp is driven hard. Cheap or very old products have none of that and will depending on some factors sometimes or almost always trip the breaker on power up.
Don't get me wrong here, what follows is not meant to offend you: Line Arrays or "not quite Line Arrays" like the T4 are indeed made to be handled by people knowing exactly what they do, like knowing how to use the curving and output prediction software or why you need a certain length of array to get the benefits of why you wanted a Line Array in the first place. Again, not to offend you, but the fact that you made some big mistakes while using them like running them fullrange over the subs or not aligning them in the time domain shows you have some things to learn about using a LA or PA gear in general. I somehow even fear you ran your 725s over the 728s in fullrange, too.

Send what you need to the tops either via crossover or via L/R with HPF engaged...send everything else to the subs via a separate EQ'd feed, will be much cleaner sounding that looping and sending full L/R to subs and top boxes. The T4's will play much nicer if you do you filtering around 90hz.

Thank you for the clarification for the "inrush current" as I never saw that before and the only reference I found was in Wikipedia.  For the SRX I used the JBL presets from Harman Kardon and I was sending the full signal to both and all the processing was don inside the amplifiers, the advise was provided here and always worked well. I agree I have a lot to learn and that why I posted in the Lounge, the mistake for the T4's was thinking they have more processor inside, I could not find any info, as their website is almost blank, lets face it that DB Technologies is an entry level product, just compare it to the L-Acoustics website and you know what I mean. They are serving me well but as I learn I will move to a professional Line Array.

Post by: Jens Droessler on June 16, 2014, 06:18:28 PM
Yes, if you use the correct factory setups for the JBLs on Crown amps with integrated DSP, the processing is correctly done inside the amps. Those setups provide the necessary filtering and time alignment (delay) for the mentioned combination of speakers, which will be high pass and low pass for the subs and a high pass for the 725. The DVA t4 on the other hand are made to be get the needed high pass from the DVA subs "high out" (or whatever they print on that label) XLR output. If you use other subs, you'll have to provide a fitting high pass in other ways, like you already found out. Now you'll still need to put a delay on the T4 if you want to use other subs than the S30. Maybe even there you'd be better off by using an optimised setup done in an external digital speaker management, since the S30 is probably made to work along the T12 and T8, which have other latency. So the phase response wouldn't be ideal if you use the T4 on the S30.

I guess you're on the right track.

The T4 box when flown makes a great system, experiment with the presets to see what they do and your musical taste . They are not cast in stone settings. We use ours on mostly the #2 position and sometimes #3 setting for our tastes. We also couple them with a 15" sub crossed at 120hz and set the top boxes accordingly, but we use our mixer outputs to do this and not a dedicated processor. With the tops (T4) crossed around 100 they really shine. We have done crowds over 1000 peeps at high levels and everyone that has heard the T4 rig is amazed at the output. The attached pic is from one event with did with the boxes and the sound output carried quite some distance. As others have stated, the best thing you can do is more boxes and get them in the air. There have been many events around the world using the T4 boxes in lines of 20 per side that have done some large venues, but overall, the T4 fits a great niche and does offer performance that is very hard to beat for the price. We have moved to the T12's but still use T4 under for front coverage and front fills, also pole mounted for smaller events.

I did my first large event with the system, it went very well. I used 7 T4's per side stacked on top of the stage and 2 S30 and 3 S20 center in front of the stage. Attendance was about 3000 in front of the stage but many more in a huge lawn in a park in Atlanta (Piedmont Park Lawn). We had plenty of bass, tops were at the limit. Everybody very happy. System was loud enough but especially clear and the throw distance was very impressive, you can hear, feel the music and understand very far away. Not enough for a rock concert but plenty for this application. My plan was to fly the system but couldn't rent the motors. We used also 2 X32's, All the inputs to the one in the stage and from that  to the other  x32 thru de aes50-a port, worked great.  Cheers Mauricio.

We are finishing an install of 7 T4's flown per side over an S30n per side, HS performance auditorium.  For the price, after we tweaked the angles, they were better than expected. 

For louder bands, either 2 subs per side, or 8x T8's per side over 3-4 subs per side would rock.
