Summary: Got it in clearance (think it was deal of the day a while ago). Works (sounds) absolutely fantastic. Have it on Yamaha 5.1 channel amp and Klipsch Icon 6" speakers. Live in apartment complex so haven't turned up really loud yet. From when I have turned it up a bit, it sounds great. Highly recommend.
Summary: Upgraded my older home theatre setup with this subwoofer and I have to say WOW! Love it. Still looking for best placement but already considering a second SW-350 to complete the arrangement. Current equipment: Yamaha RX-A820 7.2+2 receiver, Klipsch KC-25 center, KF-28 fronts (in bi-amp mode), KF-26 rears and KB-15 bookshelves (presence/zone 2).
