surround sound system with two speakers ?

I don't know how a processor could create silent sound waves from speakers in front of you, to travel to where the rear speakers should be then amplify them to audible levels and then reverse the direction of the wave to travel back to the listener. Aren't sound waves somewhat directional? Or maybe I did not understand your question. I heard the new Yamaha single surround speaker thing that is suppose to bounce the rear sounds off walls or something to give the effect but there are quite a few drivers in it. I didn't think it sounded as good as a cheap all in one box 5.1 surround setup. I am no expert by any means. If it could be done it would be pretty amazing, although speaker manufactures probably wouldn't like it much. Let us hear from the experts.

You can but most movies are recorded in 5.1 mode so when you only have two speakers you will have to buy a processor that would take all those information into your only two speakers. I tried w/ two speakers and trust me you dont want to go there.

There are several consumer based products on the market that do just this. The one that has received teh most favorable reviews is manufactured by Niro

Admittingly this single array has several drivers but the concept is similar

Bob Carver did this a decade ago. "Sonic Holigraphy" Very close to a surround sound. I believe a CT23 had it, among others. I remember you have to set it up very cafefully, speakers placement, that is.
