I've been hearing good things about the Orb Super 8 subwoofer. but mainly from users and not through SoundStage, GoodSound and others. I'm looking for a small subwoofer that is musical, clean and can reach into the lowest registers of a grand piano. Not interested in movies. Earlier, I was looking into the Hsu products, but they seem large and I really want to cut down on space. Anyone heard these? Ethan (Orb rep) feels that the Super 8 is less 'boomy' than the Hsu STF-1, which I was considering. Also, any suggestions? Thanks, ahead of time.
