Normally, on a 2 speaker system, you can still hear the rear information behind because the rear info is OUT OF PHASE. Well, I was in Sears today. I walked by this Bose sound system that only had 2 speakers and a sub woofer SOMEWHERE. Anyway. I hit a button to run the test. It showed this race car scene on the TV. I stood there in the sweet spot. OMG. I can hear the cars going from right to left, of course. And front to rear and left to right in the rear. Like I was listening to a 5.1 system. I think this is pretty cool. But since BOSE is too expensive, and not worth having that system in my bedroom, I'll stick 2 channel in my bedroom, and eventually get a multichannel system later. But I say, that BOSE system sounded pretty good.
