surround sound system with two speakers ?

to Eldarado, I don't think you understood my question. I understand what your saying about where the sound is coming from but what I am talking about is where the sound is going. No matter how many speakers you have the sound still hits only two ears and your brain processes which direction it came from. so what i was asking is if you can manipulate the sound by adjusting the time that it hits each ear, can you fool your brain in the direction that it came from.

Yamaha is selling just one speaker with I dunno how many drivers in it, but it is for surround sound. It is slim and will git on alot of TV's I believe it uses your walls to create the image of surround.....I know...I know, sounds like BOSE technology.

As Hpims says, Bob Carver's "sonic holography" tried to do this. I had it in a Carver preamp. IF you set your speakers up just right, and IF you sat up straight in a hard chair placed in exactly the right spot, and IF you didn't move your head, it worked quite well. Too many "IFs"! I rarely used it. A real sound source in the rear is much better than a simulated one.

How about with one speaker? I heard a demo of the new single Yamaha system, and for home cinema it was great. They had it matched with the Arcam reciever, and a Denon 3910 DVD player. Sound was excellent. Great for movies, not bad at all on music. Pretty cool idea for city dwellers.
