I'm about to upgrade my 10" sub, and I'm considering the Hsu VTF-3 and the SVS 20-39 PC-Plus. I would like recommendations -- particularly from those that have compared those two subs. I have a fairly large space to fill. The main listening area is 20' X 15' with a 10' ceiling; it is completely open to the back to a comparably sized kitchen/breakfast area. To top it off, between those two areas is an open entryway leading to a dining room and living room. My current equipment consists of the Axiom M60ti's, VP150, and QS8s powered by a Denon AVR-3803. My usage is 70/30 music to HT. But keep in mind that with the M60s, the subs are rarely used in music.

What do you suggest?
