Actually, if I were only be interested in 2ch stereo audio, I would likely have kept my Velodyne DLS5000. 15" of glorious bass....as long as you don't need anything below 30Hz where the response takes a nose dive.
It moves lots of air in the room, and very musical.
Just does not do justice to movies like my Outlaw Audio LFM-1EX (Hsu based design) which was a bargain IMO.
