maybe Mr. Bose... SOMEDAY might continue to develop the system into something like say the SIMULATED SURROUND speakers you have for home theater... that would be really eerie... and COOL... or crosss room stereo.. maybe one on stagae one at the back of the room. I dont know... just an idea, but certainly a kinda STEREO system for single and duo acts.. as a L1 band collectively caused natural stereo across the stage. who knows but Bose I suppose

er, uh.. OK... how about this.
bose makes a 1/2 radiator that runs off a packlite for stereo.... huh? eh? eh? eh? I just dont beleive the poles have to be far apart to get stero effect.. that would negate the fact roland JC120 wouldnt do stereo chorus, but it does and the speakers are like 6'' away. or stereo keyboard amps make a nice phase in stereo.
