Title: got growlers? i want reviews + pics!
Post by: josh cohen on June 01, 2007, 01:48:11 am
got jtr growlers? what mains are you running with them? i want to hear success stories and see pics of setups using growlers.

i think i've caught the growler bug. i do a lot of dance (techno) shows and think a pair or two of these little loud guys would be rocking.

Josh-

Jeff Permanian probably has more pictures than anyone else since the Growler is a fairly new product.

As for reviews, you've seen what's been said in the Product Review forum, and you might want to find the NY Subwoofer Shootout threads there.  Look for posts by Elliot Thompson.

Not in the same league as the BassMax Triples or the Danley TH215, but for the size, weight, and program material they performed impressively.

If I were building a club rig that I had to move myself, I'd probably purchase Growlers.

My rig, which I will get some pics of in a couple of weeks, is 4 growlers stacked 2 per side with QRX212s on top.
The 2 Growlers stacked gets the QRX up high enough.

I have heard Mike Christy's pair and while I like em a lot, more is better.

I am powering them now one per channel on a pair of PLX3002s but want to go to bigger power for them such as a PL6.0 or Crest Pro 9200.

Josh, like my mini review states in the Prod Review area, Ive got one RMX2450 bridged into each Growler, that's about 1500W into each. The only time Ive seen those amps clip was when Rob and Will were over to checkout the Growlers (maybe it has something to do with Rob, that clip issue just seems to follow him Shocked ) Just kidding... it was some sub killer track on the shootout CD that did it, but no majic smoke.

I dont think it was a fair listening test at my place, the cabs were setup on a screen porch, kind of coupled but not really, facing an open sliding glass door into the house, and 1/2 the side of the house, it was LOUD, but I think even louder inside the house - across the living room and by the kitchen sink - let the wave lengths unfold. I dont think we realized how loud it was until we tried to talk to each other - it was very clean. I do plan on getting another set, with 4 they will cover any size gig I will be willing to do.

None the less, I am VERY pleased with them, they are easy to carry/move, sound good and low, are musical, look great, I cant find a flaw, they are perfect for me. I think if you are doing DJ stuff you will love them. Alot of my gigs are DJ/hip-hop, and those kids are amazed by them, they have never heard such a small system put out such a quality sound, although, I think they get crap systems lots of time, and engineers who dont give a rat's ass. Last gig they said there was to much bass - what the?!

I digress... I have a gig Friday night, Ill post more pics than are on the pisces sound site, and a short review on how they make Vdrums sound, should be interesting...

Mike

What do you think 2 JTRs vs. 4 yorkville 808s?  Assume both boxes are properly powered...
Title: Re: got growlers? i want reviews + pics!
Post by: Mike Christy on June 20, 2007, 08:30:59 am
That's a tough one, Ive never heard the 808s. Obviously the Growlers are horn loaded and the Yorkies are a pseudo loaded/reflex design. Yorkville has found a nice trick in tuning that box (so Ive read). I almost pulled the trigger on some 808s, but got the Growlers.

I think the cabs are going to sound different. Horn loaded typically take less power to generate the same SPL, but are better used in pairs (or more). Ive read the 808s can be violent but dont go as low as others.

Im sure everyone's sick of reading my same Growler spiel, but they are musical, smooth, full, and do go low, especially for their size. They are 100db @1w/m ( @60Hz I think, help someone? ) - that is a real measured spec. Yorkville doesn't publish their specs like that, I wish they did, at least we'd have some kind of starting reference, even if on paper.

<Begin Speculation> Im not sure 2 against 4 would be a fair fight, maybe the edge to the 808s for raw driver count and physical radiated cabinet area, by how many dB? Who knows. And what does it sound like? If your doubling the cabinets and doubling the amps your going to increase the SPL, no matter WHAT cabinet your up against. I'm certain you'll hear a different quality of sound from each set of cabinets, and is that the sound you want?
</End Speculation>

Now 4 against 4? That's a different subject.

Post by: Jeff Permanian on June 20, 2007, 10:57:48 am
 One to one the Growlers would have no problem keeping up with the 808s even though the 808s are 50% bigger, and cost 22% more(msrp $1099 vs JTR $899). The Growlers use 18mm birch with Line-X truck bedliner coating vs 808s 15mm birch with black paint Shocked .

There have already been so many positive things said about the JTR Growlers on PSW so please forgive any redundancy in this post. But for anyone who hasn't had the opportunity to hear and/or use with these subs, I want to share my recent experiences with you. My take is from a slightly different angle…..I purchased twelve of these great little cabs.

I started out by purchasing four Growlers from Jeff (great guy, easy to work with, and very knowledgeable), and was so impressed that I ended up purchasing twelve in all.

My reason for acquiring so many was to have the extra head room if needed for a large outdoor event that took place this past Memorial Day with 5000+ in attendance. As it turned out, I believe that we could have gotten by with just eight (four a side). The Growlers are very efficient and capable of high power handling.
We setup the Growlers in L-R clusters, mouths coupled, with eight Martin H3s on top. The system slammed! It required very little EQ and in fact, we ran the low end flat to the cut-off freq….around 35Hz. The output from the Growlers was incredible!
The lineup for the event included everything from jazz, to rap, to a high octane (but great!) rock band which included former members of Oingo Boingo. The Growlers pounded out the low end with extension and output that rivaled or beat any of the best dual 18”s we’ve used in the past and with much better sound quality! At about 500 ft back from the stage, the low end pounding was still very pronounced.  
Other than some stage and power problems, the event went very well. Lots of compliments on the sound system from both the audience and performers alike (lots of references to how “fat” and “full” the system sounded) and we were offered the contract for next year’s event.  

The Growlers are amazing subs especially when you consider their size, and keep in mind they’re loaded with a single twelve! They produce what I can only describe as a very in-your-face wavefront that for lack of a better term, “growls”. The sound is full, with the kind of impact that you would expect from front loaded subs. I can't get over how much I appreciate the immense sound from such a small package! Not being the youngest guy in the sound business, size and weight have become very important considerations when contemplating purchases and upgrades.

Of course, we’ve used the Growlers on a smaller scale, one or two a side for indoor corporate gigs. The bands are usually bass heavy, seven to nine pieces, for crowds ranging from 300 to 500. We’ve had no problem filling the rooms with plenty of punchy low end that keeps the dancers on the dance floor.

Needless to say, as a satisfied customer I'm very impressed with the JTR Growlers. If you have an opportunity to hear them, I urge you to go check them out. It'd be worth your time, money, and maybe your back! Can't tell you how many times we've seen smiles appear on the faces of drummers and bassists during sound check owing to the fat sound that the Growlers deliver!
Jeff’s other cabinets are due out soon and I hope to check them out as well….. a pair of his tops to start with and possibly expand from there.

I want to second Mike Christy’s “big thank you” to the folks who organized the NY shootout! It was through the shootout that I first became aware of the Growlers. The shootout was very well done and the information, discussions, and observations that followed have been invaluable to all of us who couldn’t attend.

Note to folks on the west coast: if you are attending the upcoming National Guitar Workshop in L.A., the Growlers will be used by McClendon Audio Inc. for all the live performances.  

Best regards,

Roy

Do you per chance have any pictures of this?  Becuase I'd love to see how that looked with 12 of these things  Shocked

Also I'm personally VERY interested in getting a pair of these - hopefully by Christmas - to replace my ES608s, which while I love them I'd like something that can go lower.  Plus I like the idea that Jeff is right here in the Chicago area!

How would a pair of Growlers compare with a Peavey QW218?

from the reviews above, it seems apparent that growlers are putting double 18" cabinets to shame, both in levels of output, and ease to  transport.. peter, since you and i both have the same size rig and mains, i think growlers would be ideal.

(im at the halfway point as far as saving up for a pair)

Hi Peter,

Here are a couple of pictures from the Memorial Day event....I was hoping to post them sooner but couldn't figure out how to reduce the file size.
Regarding your other question, I'm sorry but don't recall using the QW218s. I'm sure that others here can chime in on that.
As another possibility, since Jeff is in your area, maybe the two of you can arrange a side by side evaluation.

Hope to see some LABster's this weekend.

Ivan-

Ah, memories...  a band I mixed years ago had a recurring gig in a little club in Olathe, KS (KS side of Kansas City Metro), about 4 blocks from the state school for the deaf.  The club's music roster leaned toward the "hair metal" of the day.  Probably a 60/40 ratio of hearing to deaf customers.

The "students" had a blast.  They could feel the beat and had a great time dancing.  It was also fun to watch them converse with sign language from across the room, and "eaves-drop" on other conversations.  It was also kind of ironic that they'd come by the mixer and give me thumbs-up and a smile... my most appreciative audience only knew me from the feel of my mix... Laughing

Thanks for the memory lane trip, Ivan.

Yeah those gigs are weird.  Once I had to do sound check with a coule of thousand kids in the room, and they were carrying on "talking" and I could talk to the stage without a talkback mic.

I also lots of thumbs up, right after they pointed at the subs.

They were really happy to be there, something you don't get from normal gigs.

The biggest issues I had was being asked to turn the horn waaaay down, as the loud HF would tend to hurt some of the kids who had a little hearing and it would overload the hearing aids.

They (the people in charge) said they did not care how it sounded quality wise, as long as the bass was really pounding and the lights were flashing alot.  If you didn't have pounding bass you would not be hired back!

I always enjoyed doing gigs for them.

This isn't techno, but here is a Growler from a church install.  It was recessed into this cement walled cavity.  We used 2.  They are great sounding, and small- although not light but very solidly built.

Jeff even delivered them himself last week with an 8hr drive to get them to us in time!  Great service.

Some cabinets, especially horn loaded subs do not have the room inside for an amp.  It would compromise the air path expansion.

I don't know if this is an issue for the Growler, but it is with some cabinets.

I'll second that.... Jeff, a powered Growler should sell like hotcakes, totally ideal for the market you are serving.  How 'bout it?


Even is it made the sub 2" deeper, gained 15 lbs and added $500 to the price tag?

Considering I would spend at least $450 on I what would say is a suitable amplifier to power the passive version, yes.
At very least a detailed market study is in order.
Weight wise, it is either a two man lift or a heavy duty handcart for anything over (roughly) 80lbs so the extra weight would not be a huge issue.

The second part of that question is IMO the more significant. It appears the calculus made by humans in purchase decisions, tend to resist the higher price point of powered cabinets despite the often improved value equation.

I am a fan of powered speakers and while subs don't benefit as much from multi-amping and active crossovers as full range boxes, powered subs are attractive since the designer can dial them in and hopefully make them harder to kill.

I expect with powered subs it will be difficult to sell for a premium over stand alone amp solutions which keep getting cheaper.

In the future they'll all be powered with a digital input port, but there will be a lot of traditional boxes sold between now and that future.

Good luck.

Jeff,
For a similar comparison, Yorkville sells the UCS1p and LS800p for about $1150-1200 in terms of typical selling price (not MSRP). Those are decent powered subs at a good price, they've sold a lot of LS800p's for sure. If you could offer a powered growler in that price range, you would have a much more compact package which would have an edge over those products IMHO.  Take the free shipping out of your deals and you could probably get close to Yorkville's price range.

But, don't jump into this without some serious research.  See if your market will support it.  Also consider warranty implications, you would have more to potentially support.  JR is absolutely right about people sometimes having difficulty understanding all of the added value in a powered rig.

Cheers
Jeff

Hey!

I am looking at purchasing some Growlers and I was just curious if you have been able to get that chest thumping low end out of them?

How have you been best able to get this and with how many Growlers?

The reason I bring this up is someone said that they were able to get that some of the time and I am just curious if the Growlers are very capable of moving the amount of air to get the chest thumping low end!

Thank you for your time!
Phil Lewandowski!

Hey Phil,

After that chest thumping low end? I'm sure you can get it from the growlers, but chest thumping is a bit subjective, and I would generally peg it at a higher frequency than real sub action, more like 60-160 HZ. I'm not a very big guy though, probably the bigger the barrel, the lower the thump.

Going lower, feeling your pants legs flutter is a sure sign of "moving some air". A couple octaves down from the chest thump, the "eye wiggle" is even more extreme.

You need  staccato, "punchy" stuff to get chest thumping, heavily damped kick drum is the usual suspect.

That said, to this day, the most chest thumping action I have ever heard were the guitars for Humble Fu*%ing Pie (thats how they were intruduced)4-13-91 at Sam's (now First Avenue) in Minneapolis. The guitars were panned hard right and left, and at times it felt like someone wrapped a packing blanket over your chest and 8 guys with baseball bats were beating on the brat.

Most of that juice would have been centered around 160HZ, and it was the only time I ever saw anyone thermal one of our low mid amps. Anybody know that sound man? He was the guy on the cover of Humble Pie's "Go For The Throat" record from that same time.

Chest thumping low end will depend on the size of the room and how close you are to the thumpers, two should get you going.

Growl on.

Hey!

I'm looking for amp to power 2 Growlers then eventually 4.  I am looking for alternatives for powering it in stereo but I don't have the money for the PL6.0.

Has anyone used the QSC RMX5050 on it?  Either at 1 per channel or 2 per channel?  It seems like it could work decently!

Peavey CS4080Hz would be a relatively inexpensive way to power up to 4 growlers, and it should be a very reliable amp.

+1 on the 4080HZ The last big gig I did, the other sound guys came to check out my rig, they swore I had big Crown sub amps, I was running 4 horn subs off a CS4080HZ, no lack of low end. I run this amp hard at all night desert raves off a small genny with no problems after over a year of abuse. Just be aware it is designed to drive 4 ohm per ch minimum impedance.

The 5050 would work great for 1 pair of Growlers....that what I have. If you go for 2 pairs, each Growler will then lose some power and headroom, but it will probably work OK though. For maximum results use one 5050 per pair of Growlers.

Post by: Jim Duyck on December 10, 2007, 11:55:53 am
the only thing I would say with running is two 5050's for 4 boxes is that $$$ easily puts you into the cost of a brand spankin' new PL380 and way beyond a used PL6.0II in the $1600-$1700 range.  But if you had a 5050 laying around and needed to power a pair, I'm sure that sounds great!  

And don't forget about the other differences like 24 lbs. and 2 rack spaces for the PL380 and 150 lbs. and 6 rack spaces for the 2 5050's!?!?!?! Rolling Eyes

Not that I'm there or anything - our 4 Growlers are still on a pair of bridged 2450's...

And in that particular case, you would be TOTALLY BLASTING the people right next to them in order to try to get any  low end at the back of the room.  I am all aobut EVEN coverage-or at least as best as you can.

There is no one size fits all when it comes to sub placement, it varies from situation to situation.
Title: Re: got growlers? i want reviews + pics!
Post by: John Halliburton on May 02, 2008, 09:03:03 pm
William,

Yes, I agree, they would provide more bass, but as Ivan points out, the folks in the front center would be dying from bass.  The first row is only 9' back from the edge of the stage, and I'd have to set the subs on the floor, so they'd be about 7' from them at that point.
What I get from the setup shown in the photo is good coverage, my Trik Traps elevated to a very nice height-they provide coverage to the balcony seats nicely even-and really good sightlines.  Only the widest seats in the first few rows will have a bit of sightline issue.
If I need more output in that room I'd stack the speakers on the landing in each corner formed by the proscenium and adjacent wall, gaining some boundary reinforcement.  I can also add more subs and tops there too, there's just enough of a footprint.  An added bonus is sightlines improve even more then too.
I've had a full house listening to this exact system, 650 reunion crazy local Irish/Folk music fans with their favorite six piece band doing a 20th anniversary show, and everyone could hear the show no problem.  Now I know I'd need to double FOH for an electric group of some sort at the least.

Best regards,

John

Ivan,
While I can agree with you.. IF the bass is lethelly loud.. my experience has been that people are less bothered by bass when sitting near the subs than they are by highs at the same volume level from the tops.
Some years back, I did a center floor sub for a church. Was testing it when a member of the congregation who was a Hi-Fi enthusiast showed up. He was REAL impressed with the quality and amplitude of the bass. He asked how in the world can the front rows tolerate something that loud. I said, go sit up in the second row, and see for yourself. His response, "no way, it'll blow my ears out!". Still, he ended up doing so, and was astonished to find the bass wasn't perceptibly greater than it was at the back! Plus, I have seen so many churches that do this.. and the front rows aren't blown away. I know you have, too.  Smile
As I said, I will agree.. but only if the subs are waayyy loud!
Regards,
Title: Re: got growlers? i want reviews + pics!
Post by: Ivan Beaver on May 03, 2008, 09:54:56 am
It depends on the particular situation/room etc.

In the past I have put subs under the front of the stage-mainly because "that is the way many others do it".  Once I started looking (and listening) at other options, I have changed my way of thinking.  I have not put a center sub(s) under the stage in the last 500 or more installs.

I would agree that the level the bass is run at can make a difference in "perceived" level.  At lower levels it is harder to detect variations in level.  The upper freq cutoff and musical content can really affect "the effect" also.

In most cases (that I am involved with) center subs in front of (or under) the stage is the LAST thing I think of regarding placement.

But different people have different needs/wants out of a sound system, so they have different approaches.
Title: Re: got growlers? i want reviews + pics!
Post by: Michael Hedden Jr. on May 03, 2008, 10:24:35 am
I think the whole question of sub placement especially in larger rooms has two primary points.  One is practical, you bring the subs in, it's the big box that may or may not be flyable and even if you can fly it, it's typically big so you put them on the floor with spacing that guarantees uneven coverage, and real issues with the inverse square law, thus the whole "where to put the subs" discussion.
The second is physics, front loaded subs due to their inherent lack of sensitivity compared to horn loaded subs, benefit/need boundary coupling just to get close to the desired levels.  Three to four times the ground stacked subs need to be placed close to at least one if not two or three stiff boundaries.
As Ivan has said if you ever get a chance to hear properly flown subs the even/consistency of bass response over the entire coverage area will change the way you look at it and I don't think you'll ever go back to them on the floor again as your preferred way of doing it.

Mike,
I would certainly not argue with the experience you and Ivan probably have that a horn loaded sub can be flown with much better results than a front loaded sub.. just that I have only ever seen ONE system with flown subs that worked properly. And I would certainly agree that having a boundary, such as the floor, for a front loaded design box seems to mitigate a lot of the issues that flying creates for that design type box.
Another thing, though, is I know I see riders that say very clearly about NO FLOWN SUBS.. probably because they are thinking about conventional front loaded boxes sounding so poor up in the air.
Anyway, I'm not contesting your experiences.. only relating mine.. which I have not had the privilege of getting to work with as much in fine equipment as you all have.  Sad

Kevin,

I have some Growlers in Napa, including a demo cab that you can try.

One pair in my inventory have the T-nuts installed for 4 caster mounting on the rear. The standard handles are routed into the top and bottom rear edge. You should talk to Jeff about the possibility of adding handles. It should be easy to put them in the horn mouth area, but I don't know how that may affect performance.

I was just checking the QSC site.  You can get the 700W plate amp for the HPR15i for $300 from their parts website.  40Hz sub filter and 100 Hz Hi pass according to the schematic.  They also have the gasket and installation screws as parts.  i think ythey use a locking IEC cord as their AC power.

However, I'm not sure if the plate would fit the back of a cabinet without compromising the bracing or the folded horn air path.

I discussed this w/Jeff at JTR awhile back, only with Speakerpower modules.  He didn't seem to be interested in developing a powered version, and said the power would add about $1000 per cabinet.  He was also concerned about air leaks from adding a module, and thought powering from a separate amp was a much more desirable than self-powered from his perspective.  After all this, he said if you want to buy a Growler and void the warranty and hack it up to put a module in it, go ahead...

Speakerpower will not sell modules in small quantities, last time I checked.  They are a little more high powered than the QSC's and the DSP can be adjusted to the speaker, where with QSC's you are stuck with their factory module settings unless you alter the module.  The 40 Hz rumble filter and 100 Hz low pass point seem about right for the piece, though.  Not familiar with the other modules you mention.

The speaker power modules DSP cannot be adjusted by the end user.  It is a preset type situation.  It can be programmed as needed by the manufacturer.

Post by: Rick Powell on February 10, 2009, 08:37:17 am
Ivan,

You deal with the modules all the time, and I will defer to your knowledge, but I thought the Speakerpower modules could be set by the end user with a PC interface...however, the process is somewhat cumbersome, and must be done when the module is "out of box" and cannot be programmed on the fly like a Crown I-tech.  I believe Simon Coffin, who occasionally posts here and built some self-powered coax monitors with the Speakerpower modules, could chime in on this.  Or Brian Oppergaard, who actually builds 'em.

Also, looking at the Digmoda model previously mentioned...it looks like a re-badged Speakerpower module.

On the older Speaker power units, it is purely a one way street.  First you have to have the physical adaptor needed to convert your computer.  Then there was the very coumbersom TI software.  It does NOT look like any DSP you have EVER seen.  It took me a bunch of questions to even figure out how to do a couple of basic things with it.  To change even one setting (say decrease by 1dB a filter)in the eq for example-it is like a 12 step or so process.  Then measure-and go through it again if needed.  VERY time consuming.

If you hook up your computer to a unit and turn it on, it will erase the stored data-and you will get no sound out of it.  You had better have a working program you can load into it.

You cannot "read" any data from the unit.

Brian has a new DSP out now that has ethernet control over a couple of the user functions.  But the "real workings" are set by him, and as of now, he is the only person who can program them.

They have simular response as the growler, 103db 1 watt, 18mm 13ply baltic birch, 120 lbs, 36" x 24" x 26" and load with a 15" driver 600watts continous/1200watts program, 17mm xmax. I'm holding for building them because I want a more powerful driver.


What about a growler with a pair of 10s? I seem to remember you telling me about the possibility of doing this.

The pair of 10s will displace just as much as the 15, they will fit in the enclosure of the standard growler. You get the power handling of the 2 voice coils (2000 watts program?), a weight increase of ~12 pounds and a sensitivity increase of 3db. This seems like a good way to go.

Why is every so hung up on "wanting more power?" That seems to be the new trend "my box handles X watts, so it's better then yours!" I'd rather have a 500/1000w driver in a box that'll do 136dB peak vs. a 1000/2000w driver in a box that'll do the same. The less power, the better IMO.

Evan,

Jeff is almost assuredly not speaking about the drivers' input power capacity.

He is likely speaking of 1 of two things:
1.  A driver with a higher BL product for the motor
2.  A driver with more usable XMAX.

Given the extremely short horns used in the growler boxes, I am suspecting number 1.

From a speaker designer's perspective, I can tell you that for modern loudspeaker drivers power handling is almost NOT on the list of things to concern yourself with.

Certain more meaningful parameters, such as increasing a driver's BL product, happen to include the side benefit of building a motor structure that can deal with greater input voltages.

I doubt if he wanted the more powerfull driver for the sake of bragging rights. Yes, I see the value of getting the same amount of output with less amplifier power, but there are many other variables, trade offs etc. involved there.

Evan,

Not a new trend at all.
Around 1983, the EVM Series II speakers came out, handled twice the power of the original series, and were 3 dB less sensitive.
The speakers were "winning" over the amps.
Amps got bigger again, speakers had to catch up again, lest they get a reputation as frybabies.
The trend merely escalates with each generation. Back then it was a 100 to 200 watt deal.
Now it is 500 to 1000, or 1000 to 2000 or more.

So what is the advantage or the difference if the efficiency and response curve is similar, but the cabinet is bigger and heavier?

My thought exactly. There must be something missing in Jeff's summation.... I can't imagine him going after the B-52 type market of bigger is better and badder.

Maybe the lack of a big difference between this and the standard Growler would explain the desire for a more "powerful" driver.

The obvious difference and advantage is the 3db higher sensitivity and the slight increase in power handling.

I'm wondering this too. I would have thought with the bigger box that that horn path would be a little longer and the mouth area bigger giving it the ability to extend a little lower, sounds like thats not the case though.

The goal was for one 15" version to equal two Growlers, 3db more efficient and double the power handling. The 15" in these prototypes was just for proof of concept and actually handles less power than the Growler driver. Getting a 15" that meets the design goal is proving to be difficult. The dual 10" was the first plan however the high excursion 10" had very little SD, weighed 27.5lbs each, cost within a couple bucks of the 12" so the dual 10" had less output than a 15", weighed much more and cost much more.

Sounds like a winner...I'd have to seriously consider it when I'm in the market for subs sometime later this year.  Perhaps a manufacturer could "OEM" one to your specs.  Heck, the Eminence LAB 12 was born of a DIY cab, and they likely had no idea if the product would have a steady clientele.  At least this driver would support a comercially manufactured product with a potential shelf life.

Well, by wanting to increase the sensitivity by 3db and double the power handling of the standard growler with the 15 inch version it would appear that he is almost assuredly talking about input power capacity and that you were wrong.

Either that or am I missing something.

Mark, you are indeed missing something.

The vast majority of modern drivers, in almost all speaker alignments, have more power handling capability than they do excursion capability.

Practically, in most loading situations, the way you add power handling is by adding XMAX!  A few very good horn-loaded systems, the best of the tapped horns, and some 6th order bandpass systems have enough driver loading to provide excursion control sufficient to render them voice coil heating limited, rather than XMAX limited.  A short horn like the growler is almost assuredly going to need as much XMAX help as it can get.

Increasing the sensitivity 3dB would require a driver whose parameters are more compatible with the horns' acoustic impedance, to improve the power transfer.  Depending on the nature of the horn that is going to lead a specific BL product target, hence my note 1.

Edit:  I figured out the driver used in the Growler, and it only has a moderate BL product, so perhaps a higher BL product will not be needed.

That makes sense. Adding to the xmax adds to the power handling (if the xmax is the limiting factor) and Jeff wants to add to the power handling. When Jeff said "3 db more sensitivity an twice the power handling" I wasn't thinking about the possibility of the xmax being the weak link.

Hey Jeff, what about putting two 12's in the super growler? It would save you the trouble of having to source a 15" driver. I have absolutely no experience in designing or building speakers so please excuse my ignorance if there is an obvious reason why this would not be a consideration.

Personally I would be all over a dual 12 growler that took the place of 2 growlers (as long as it was under 135lbs and less $ than 2 growlers)

I bought 6 growlers from you a year or so ago after renting Rob's 4. I put 2 in a club and kept 4 for myself. Mine have been great but the meathead dj's in the club managed to blow both drivers in the club (at different times). I had them running parallel on one side of a rmx 5050, I took that out and loaned them one of my LG fp6400's and they have been fine ever since, only problem is I want my amp back but don't know what to put in there instead.

Anyway I have been wanting to buy at least 4 more growlers so I could do 4 per side arranged like the pic from the beer fest with the 4733's on top. but it would be sweet to be able to get two more subs that have the output of 4 growlers. Although I am not sure what it would do to the sound to mix the subs like that, then again it is probably a waste of time to continue with endless speculation. Whatever design you decide on I am sure it will be amazing.

Oh and if I can ever get my credit card debt paid down I have been dying to get 4 or 6 triple 12's, any chance you could make triple 12m's with pole mounts and feet on one end so that they could be used as monitors or mains?

Here is a video of me and Jeff playing around with 2 growlers. The amp used in this video was a QSC plx 1804 which is 900 at a 4 ohm load (450 watts per growler). I know they were EXTREMELY underpowered but here is a sample of what the growlers can do even when they are EXTREMELY underpowered. Very Happy

The Triple 8's were about 8 feet in front of the Growlers so I didn't use any delay. The building was locked up until one hour before the event so we didn't have much time to setup.

I think I enjoyed myself more than anyone else. I am a bass man and oh boy did those 6 growlers deliver. The triple 8's held their own in that gym. At the back of the room, the highs were very clear and the bass was hitting hard. In front of the growlers, me and Jeff had to hold our ears lol. Our only problem was the Lab Gruppen not getting enough power. We only had 30 minutes to set up.
