I got my STF-2 B-Stock last week and I finally got my receiver back from service today. The sub is excellent. No blemishes or anything else on it. It looks new. It sounds great with movies, music. One problem I'm having is that it doesn't seem to be working much with TV. I'm watching Lost and it seems like the sub just isn't there. My cable box is set with Dolby D EX, as is my Receiver (Onkyo TX-SR502). Maybe there just wasn't much bass in the show, I don't know. I haven't properly calibrated the sub yet (don't have the SPL Meter yet), should be done on Friday. Any ideas?
By the way, B-Stock Subs at HSU are 20% off of original price but you don't get the 30 day money back guarantee. The warantee is still 7 years.
