I have an SVS 16-46 PCi in a 400sqft room which seems to shake everything in the house but the chair I'm sitting in. I've moved the sub everywhere in the room possible, given its size and the existing furniture. Can't seem to fill the hole no matter where I put it. I'm thinking of adding an Hsu VTF-2 to place under a table right next to my listening chair, but I'm wondering, given the Hsu's size, if it is really that much better than everything else at that price point, since I've never listened to it. Someone mentioned the Paradigm PW2200 as being as good...but that sub is $200 more. I've spent the last 2 weeks looking at everything in Austin, Texas, on the web, and can't seem to find anything that souinds as good a smy SVS. I can't understand why Hsu is supposed to sound better than everything I'm looking at which has the same dimensions and power. How can Hsu's sub be in the same class, given it's size compared to my SVS? I've read on here in the past several months the Hsu VTF-2 (I've been reading all this before the announcement of the new VTF-3)is comparable to the SVS...but it is so small.
