Nobody has mentioned VMPS. Great bargains for the money as has been known for years and will do music and HT quite well. Check out the VMPS forum at audiocircle.com. Not too many subs can out do the Larger VMPS. These are passive so will require a separate amp but at 700 bucks for the larger with a used power amp you're not going to get much if any better for the dough and quite possibly not as good. VMPS's bass has been praised by owners and reviewers since the 80's as some of the best bass for your dollar available. Cheers
