Sorry, I'm not trying to preach, just trying to help before you make a bad decision which will cost you more money in the longer term. The point wasn't about the subs, but it is related. It was about dropping back from 15's which typically have decent response to about 80Hz to 12's which typically fall off above 100Hz. This leaves a hole in the mid-bass response and makes the system sound a little off. You will be faced with 2 choices:
- Use the subs to cover this range which usually won't work well.
- Use a narrow band equalizer with a boost at 90Hz.
At low volume levels either solution will almost work, but when you crank it up you will be faced with either weird noises coming from the sub or a damaged top. In the EQ solution you will most likely be in clipping and depending on the amp design it hopefully goes into protection mode before it melts a voicecoil in the tweeter or damages the woofer from over extension. Has anyone heard a woofer hit bottom? Ouch!
Just trying to help.

Sorry, there is another obvious option that I didn't mention. Get subs that cleanly cover 120Hz and up. Most front facing 15" subs should be able to handle 120Hz, but this opens a new can or worms. You then (possibly) have directional audio coming from a sub. You should then run stereo signaling to the subs, place the sub very near the top, make sure you have the L&R systems connected properly so you don't have a Left top paired with a Right sub. You can't run a bridged mono sub amp. You lose out on the ability to couple the subs and you have to deal with the big bad phase cancellations.
Scott, I see what you are saying now. I never thought about that actually. Another issue altogether is that I haven't heard the Growlers myself to co-sign that i like how they sound. Before i spend up to $1K on a speaker i would like to hear it first. Its different with lights to some degree, at least you can see the production as opposed to trying to hear the JTRs via a youtube/vimeo video. Also, the Growlers are 86lbs and my Turbosound is 62 lbs and YES those 24lbs make more than just a "couple of pounds" difference to me.
.
Most people that have heard them compare the (relatively) small JTR & Danley horn loaded subs with high-end portable dual 18 cabs such as the JBL SRX 728 and EV QRX 218. You really should find a local vendor, DJ, pro audio outfit or pro audio trade show who has them and hear them for yourself.
Cam / Rick,
You both are running 12's with subs, you notice any issues as described?
Background - Cam and Rick are running the 112P's and I think Cam is also running the 118P's. Rick is running a different sub.
I have never used that mode. On nights that I know I'm going to push them I use full range with an external crossover.
I have heard that the JTR Growlers can sound muddy at times. I was going to go the CV C36 with replaced B&C Subs like my friend. THEY SOUND SWEET!!! They are monsters with regard to size but sound so GOOD!
You think that ONE JTR Growler is comparable to ONE Danley TH118?
The Danley TH-118 is more comparable to the Orbit Shifter. The Growler is smaller, more like the size of TH-mini but performance of the TH-115. Basically a TH-112 if they made one.
As for muddy I have no idea where that came from. Not mine! I would attribute that to yet another person who never took the time to learn about sound or how to setup & use their equipment.......
The CV's are old technology, long since surpassed by tapped horns but people keep buying them so they have no reason to stop making them.
What kind of amp do you have powering your Growlers? Will one Crown XTI 2000 power 2 or even 1 per sub or do I need a more powerful amp? If not, I would need to find a sub that is as loud and clean as possible, but can be accommadated by my current amps. If money is no object (Danley TH118s) then I would consider buying new amps, but for now I have to work as if my investor is moot.
The current models are specified as 2,000 watts at 8 ohms. I drive mine with a single QSC PLX3002 bridged giving them 1,500 each and I've never had to turn them up past the -10db light. OK, full disclosure, at one outdoor grad party last year I did have them just tickling the clip light for one song but turned it down after that. The kids loved it, the parents were horrified.:trismug:
When I find a big room or an outdoor event with enough supplied power I will drive them with a bridged PLX3002 each, giving them 2,000 watts. I will probably have to place an order for another pair the next day so I'm hoping that doesn't happen too soon. :tricool:

I've found this to be the best for me too. 3:00 (75%) on the tops and 1:00 (60%) on the subs.
