I haven't done much sub searching, but I've got BA's System 9000 you heard and I've been nothing but pleased with it. Between the sub's level control and the 1050's sub control, I can go from practically non-existent to too much for the better half. If you go that route, there's a connection trick someone else in this community found (forgot who!) that drastically improves the sound of the front L and R speakers.
