I have heard from many places that a properly set up 2 channel system can deliver sounds that you hear from a full 180 degree range (out to your sides). In short, I can't get this to happen. I'm trying to think what is going on that enables us to hear sound from 'outside' the speakers, or even between them. What's happening is our brain is correlating the difference in tone and phase between the same sound coming to two different ears, and then using that to determine where the sound came from. I can understand that. But how do we recreate a sound outside the pair of speakers? Is the signal in one speaker ridiculously out of phase with another? I have Kit281 speakers, which have excellent imaging. When I had the tweeters facing to between the speakers (they are asymmetrical, the tweeter is on one side and each speaker is opposite of the other) I occasionally heard certain parts of music coming from just outside the speaker (nothing major though). After reading a comprehensive review with measurements, I decided to switch the left and right speakers. Something else about the sound improved, but now there is no "extra-speaker" sound. (Note: the soundstage still has excellent depth and there's some sensation of 'height' which I don't exactly understand but it's really quite realistic somehow.) I find myself now moving my chair closer up and sitting 4-5 feet away with a 90-100 degree spread (instead of 7 feet and 60 degrees.) Still no wraparound effect but I think I like the 'size' better. You know, when you close your eyes and relax and you're almost in the band. I've also played with the toe in angle of the speakers and can't tell what I want. Pointing them away from me makes the sound a bit duller but it's easier on the ears at high volumes. And it does nothing to the soundstage. Does this have to do with the recording? The phase response of the speaker? My other equipment? What could be going on here? I apologize for the long post. This is a very interesting topic for me. Thanks for the help.
