For the best integration, I highly recommend connecting the sub's speaker level input to the outputs of your power amp. This suggestion was given to us by Audio Physics's designer (J. Gerhard?) when we were exhibiting at CES with an Audio Physics Rhea(and later confirmed when I added a sub to my own system). His logic was that, by driving the sub from your stereo AMP, the sub's sound would acquire the characteristics of the amp, yielding a more coherent handoff to the sub.
Many visitors to my home have been amazed ("the subwoofer's way over on the right, but I hear the bass smack in the middle.." or "....over on the right..").
