I was over at this guy's house this weekend, and it turns out he has a HT. It was a Klipsch (gag) 6.1 setup driven by an Onkyo receiver. His display was a 53" Sony which looked enormous in this room, but the image quality looked worse than my cheap 27" TV. The thing that really grabbed me was how much impact and presence his subwoofer had. I mean, you really felt the bass. My PSW150 certainly doesn't give me that experience, though I think it might be tighter. I suspect part of the problem is the small rooms that I keep sticking my HT into. Still, I know my sub can't deliver that much impact. Subs are one area that I've never paid that much attention to. I haven't gone out of my way to demo any of them either. After hearing the Klipsch, it really makes me wonder what a good sub like an SVS, Rel, or Servo-15 sounds like. The Wilson Watch Dog or Krell Master Reference can probably break bones!
