Looking to get a sub to complete my setup. I have the m80's, vp150 and qx8's. Im looking for a sub that is TIGHT for music on a good listening level. Im tired of muddy, floppy crap subs that dont cut it for tightness at mid levels of volume or higher. Any subs (all manufactuers ok) that you recommend in around the $800 new or used price?

Anyone ever heard the first or second version of the paradigm 1200 sub???? Some say its boomy and muddy.
