both hsu and svs said that each model was totally capable in my size of room
Capable-yes! But, will it be enough is a much better question. My former room was a little smaller than yours and a single 3.3 or PB12-NSD was
NOT enough for me. However, it may be for you as we all have different expectations. As I eluded to earlier, you could
NOT go wrong with either one. Hopefully, that will be enough bass for
YOU. After all, that is really all that matters-right? Good luck in your decision.
Cheers,
Phil
