Axiom Home Page Forums General Discussion Home Theater need sub for large room

Hi,

I am looking for a sub. A friend of mine who's visiting toronto, canada will purchase this for me. I need a 220v version.

Currently I am considering the following subs:
SVS PB12 NSD
HSU VTF-3 MK3
Axiom ep 350
Axiom ep 500 (factory outlet, if I can get it fast enough as my friend leaves in about 10 days)
Monitor audio rsw-12

Room Size

The main listening area is 19.5 x 18.5 x 10.5
3787 cubic feet. The system is kept along the 18.5 ft wall. The listening positions is about 11-12 ft.

But the Dining and open kitchen is attached to it, and the total area is 31.5 ft x 18.5 x 10.5 = 6118 cubic feet

So I guess I should consider the room to be 6118 cubic feet for subwoofer purchase purpose, right?

What specs at a minimum I should be looking for a sub. The volume of the room is large, and many a sub could fail in it.

Usage:
50% movies, 50% music.
I mainly listen to classic rock, blues, heavy metal, jazz, classical music etc.

Current setup:
Yamaha RX-V663 AVR, marantz cd6000 OSE cd player, B&W 602 S2 for mains, LCR 600S3 center channel, B&W rock solid for surrounds, HTPC with M-Audio revolution 7.1 sound card.
