 Speaking of speakers (and "accurate" sound source positioning)...

 In my teens I had an idea of a single flat panel speaker that would hang 
across the full width of your "listening" wall. This speaker would replace a 
matched stereo pair of speakers and would be able to have sounds emanate from 
any point/points across it's surface. 

 I would think that this would allow incredible imaging possiblities, as the 
sound would be truer to the single point source of  "real-life" acoustics.

 Heck if I know how this would be designed into a working unit though!
