I would have to say that you don't need as Much of a sub for music as you do for home theater. I have a tiny 100Wpc Mirage 8" sub that I bought a few years ago. It sounds very good, and does a wonderful job of filling in the bass down to about 30Hz or so. It will not give me room-shaking bass that I can feel across the room though.

That said, I bought a SVS-PB1-ISD. It is just as musical as the old Mirage, but it can move TONS of air when required to for movies.
