I think I've got my sub choice narrowed down to two, so kindly consider this: of the two, and the two only, which would you spend your money on, and please explain your rationale, where possible: Paradigm's newest version of their PW-2200, or Hsu's STF-3 (comparitive prices are within $100CDN). Usage is 100% HT, room is 30x10.5 ft, eight foot ceilings (roughly 2500 cubic feet). Room opens to a small work area and staircase (click my sig for pics of the room, and current sub placement). Presently using an Axiom EP-175 (10"); not enough slam for my liking. Other speakers used: Axiom M60, VP-150, QS8. I'm leaning toward the Hsu model simply because it will physically fit my room more easily. (The reason SVS is not on my list is because I'm in Canada, and once their subs cross the border, they are no longer as great a value as either of the other two models. BTW, Hsu has recently established a distributorship here). Just to further complicate the matter, I'm all ears if anyone cares to make a case for Hsu's VTF-3MK2. I really appreciate any help you might give. Thanks, and cheers. DS.
