actually I bought one yesterday that wouldn't turn on, so I returned it and got another one that seems to be working just fine. I haven't calibrated it yet but just from playing around it filled out my setup pretty nicely. I'm running 2 NHT SB-3 as my mains, an SC-1 as my center and my surrounds are a pair of old Spica SC-30's. I wanted a sub that would go pretty deep because the SB-3's already go down to 39hz and paying a few hundred for a sub that stopped at 30hz didn't make sense. anyway, I got mine from CompUSA, which is (currently) selling the STF-2 for only $349, that's $50 cheaper than the factory direct price. I understand HSU is trying to get them to stop this, but if you live near a compUSA and have always wanted a serious sub, I suggest you head over in the next few days. Noah G.
