Nightflier, being in CA, you really should visit Linkwitz for a listen to his Orion system. It combines all the attributes of the panel type speakers (dipoles) using much smaller piston sources (dynamic drivers). The full setup (++) includes pressure source subs that you can certainly feel, though no so much in the 80hz region as you might desire on occasion. Go give a listen for yourself.
