I have roughly a 6000ft3 room with another 2000ft3 room connected through the hallway. I dont know much beyond bigger is better biggrin.gif but am handy with my hands and have all the tools necessary. Id like the xover to be around 60 or 80, but would like to have a strong 15-30hz as this is for 90% movies/games. I have roughly $2000 to spend for the setup minus enclosure which I already have the materials lying around.

Any advice is appreciated.

You have the option to build basically anything your heart desires with that kind of budget. One example would be take 16 of these woofers

http://www.amazon.com/Infinity-Reference-1262w-1200-watt-High-Performance/dp/B0028AYIXK/ref=sr_1_1?s=automotive&ie=UTF8&qid=1341685713&sr=1-1&keywords=infinity+subwoofer

Build 2 enclosures (about 10ft3 ea), with 8 in each, 4 on the front 4 on the back (dual opposed), wired for 4 ohm total per sub. Take an amp like this nu600dsp, which puts out about 1500-2000 watts per channel, and allows you to EQ the response flat to 20hz.

You would have a pretty ridiculous system. Or you could take a pair of high end woofers and build large ported subs, but they wont match this overkill sealed system.

How big of an enclosure can you fit? Multiple sealed  or 2 big large low tuned subs would do it. Pick your poison!

Thats a good question, the space I was looking at is roughly 60L x 40W x 30H max and less would be preferable with with the length, and only have space for the one enclosure so would have to work that into the equation.

You could port a FTW-21 in that area. A 40"L x 39"W x 29"H box with a 5"H x 16"W x 35"L slot port would basically give you a 20ft3 16hz tuned box. Take an EP4000 amp (bridged 4ohm 1600 watts), and a MiniDSP eq, and you would have a system capable of over a 120db down to 20hz.

You could buy a more expensive amp, but it isnt necessary.

You may want to have two FTW-21's and two bridged EP4000 on two circuit breakers. ~120db@15hz@1m according to the box model. That would be a good start and probably be a vast improvement over whatever your using now.
