I have a yamaha reciever and a pair of boston vr-950's, dual 5 1/4's. They apperently go down to about 50hz. Well I listened to the matrix reloaded the other morning and the amount/loudness of the bass was pretty nice. I dont think I need it much louder. Now the thing is though I want a seperate LFE channel and for it to drop lower. Subsonic would be great. But I dont really need or even want to have that much more volume. I just want it to play lower and cleaner. Do I need an SVS and if I do would I be fine with a smaller one? My room is about medium size... i think about 200sq ft. It has a vaulted ceiling, and 3 openings, one door way on one side to the kitchen, one doorway on the same side to the dining room, and one "window" on that same side to the dining room. I have a wall to wall fire place on the oposite side. Well thanks in advance.
