My home theater room is L-shaped and it's about 300 sq ft (297.6 sq ft, actually). And I'm trying to figure out which SVS would suit me best (I'm currently using the 11.5 x 16.5 axis for HT). I use my system for about 90% HT and 10% music and I'm looking for some floor-rumbling, jaw-dropping, pants-flapping bass . I'm open to both box(es) or cylinder(s) and I'm willing to spend up to about $1200 (wink wink, nudge nudge). Though I wouldn't mind having some headroom in case I later move into a bigger apartment, I don't want to spend more money than I have to either (if that makes sense). PS If you have a used SVS for sale that you think would fit my needs, feel free to PM or e-mail me.
