If 2 SVS + weren't cutting it, I would think seriously about trying to go IB or some sort of diy custom work rather than spending big bucks on a commercial sub.

Shake the foundations, hmmm. Well, I have a Revel B-15 and while it is very nice it (and its big brohter) are probabloy not going to shake your foundation or anyone else's. There are, however, quite a few choices that could:


1. A good IB set up with multiple 15" high quality drivers.

2. A Contrabass

3. The Danley Sound Labs PB-12


I am sure I am missing a couple of options, but this is a good statr...


Good luck!!!

I don't know man, you must have something setup wrong. I have 2 20-39PC+ subs in my 2,000 cubic ft room which has a concrete floor, ceiling and 1 wall and these subs can shack the hell out of them.


Maybe your subs are canceling each other out or the mains are canceling them out?

Well, if your subs are co-located, the both are in the same corner and you will gain 6db.


But, my subs are non-co-located in difference corners for better room response. With playing with the phase on the subs, I get a 5db gain.


Also, try playing with your receiver's sub distance setting while playing a CD with good bass. Also, sit in the listening position and listen for a difference while playing with this setting. This helps prevent you speakers from cancelling your subs out.
