Right. The word "powerful" I used above was not well chosen. The Hsu subs are certainly powerful, but they really shine in the quality of the bass they produce -- very clean, tight and low distortion.

I am one of those people who consider that music (especially classical) is more revealing and unforgiving of the sound quality of subwoofers/speakers than movie soundtracks. In my opinion, if the sub can do classical music "right," it will do movies just fine. And I can tell you my Hsu performs music very, very well.
