Roachone: I also owned the original pair of 10" subwoofer that HSU offered. I must have bought them over 10 years ago when subwoofers are not that popular or have that much choice to choose from. Come to think of it, it's extremely cheap for a pair of subwoofers. There is no serial # or model # shown on the sub and when I called Dr. Hsu, he told me that the pair that I bought is the 6th pair that he ever manufactured - probably made in his living room while watching TV! I used them now for my home theatre set up and they are still incredible after all this years!
