Jacob George has built the Rethm horn loaded speaker for the purist. A single driver system with no crossovers whatsoever. The speaker itself has a sort of wheezer device that almost looks like the tail of a badminton, but the fact that he was getting full range sound out of a single speaker was impressive enough. The speaker is available in two models, with ($9,500/pr) or without ($7,500) the extension (shown) that drops the speaker's low end from about 50 Hz to 38 Hz. It does make you rethink where you're going to put the TV though. With extension careening off the back end, this isn't designed for those living the i-Life.
