I am still not sure why the Bose fans keep continuing to offer a $1500+ solution to a 50¢ problem...

That's an awfully expensive alternative to the question (and still has never resolved the stereo issues that many post about). Plus, what happens when someone dances into an L1? You trying to tell me they are harder to knock over than a tripod-mounted speaker?
