I recently sond my last set of 18's to make room for my custom made 21's I'm getting. As for making them all work together thats what the DCX2496 is for, timings, phase, eq etc. These are all DIY 18 and 21' subs powered by bridged ep4000's for each driver, not some sub you buy in any store.
It for sure is not the general consensus among people that actually do it. You guys should actually try it, instead of just telling me what people in papers say. There are TONS of us that have 4, 6, 8, 10, 12 etc. adding extra drivers can make a world of difference and
I'm not sure how you could think otherwise (other than improper room setup of course).
Because I've heard what happens when you have too many drivers (even when they are not scattered..)
BTW.. we just replaced the 12 18" subs on my stage with a 4 x 18" cabinet.... guess what? It got better.. and not by a small amount. (using multiple subs can indeed smooth out the response over a wider area, but I don't think the size of most home theaters requires more than 4 to do that..)
I think the science and research is fairly clear....

Your theory would apply to all speakers then if thats the case, not just subs.
How is that the case? As the wavelength shortens and directionality increases, there is less need for more drivers to decrease room modes, etc...

You telling me that if you have a 4000cf room and 4 x 10" subs are going to be better than 8 in that room? the extra 4 aren't going to make any difference? not helpful in filling a room that big with bass? common man, thats just silly. With proper setup, you can make anything worth while.
No.... but it would be silly to use 10" subs for that size room, and expect to get prodigious LF output.
IMO, you'd get more output and better extension for that same cost of 2 higher quality 15" subs in most cases...
You need to put the right equipment in first, not try get something not designed for the purpose to work at it's operational limits (i.e. a 10" sub in a large listening space...)
But perhaps the biggest issue is that the only way to integrate multiple subs in said space is expensive.
My point being is that if you are using so many drivers without proper correction, or using Audyssey to correct them, you are forcing a lowest common denominator onto that part of the B-Chain, and I suspect again, that 2 or 4 decent subs properly equalized would yield a more desirable (i.e. accurate) output.
Not to mention time alignment, etc...

You guys have got to get out of your head a traditional setup.
To what end? If you are trying to enjoy films as intended, there is no reason to go out side of studied and proven techniques.

There are lots of us that have multiple's of everything. Have you ever felt 135dB's @ 20HZ? how about 145 @ 40hz? in a home? It's something man.
It's built big and bad for one reason only, for fun
I've hard a lot of things, and felt large rooms shake... and I've heard similar in some pretty impressive home theaters.
However, I have no interest in producing that kind of output for two reasons.
1. It has no bearing on accurate playback...
2. I value my hearing as I need it to make a living. (and, btw, continuous exposure at those SPL's is not good for the inside of your body either.)
To each their own.. but I stand by the research and my personal experience.
