Monolith THX and the Hsu VTF-15h mk2 are some of the best choices out there. For a guy who claims to be so ignorant, you sure have done your homework. In this price range, I also like what an dual Outlaw Audio Ultra-X13 can do. For just a tad over your budget, consider a Hsu VTF-3 mk5 triple sub system- that will pound you into a bloody mist. If you want something that performs well but is very easy to deal with physically, consider a few SVS PC-2000s. If you want a crazy flat frequency response to below 20 Hz, consider four Hsu VTF-2 mk5s. Also look at some Outlaw Audio Ultra-X12s.
