Speaker Placement

Roscoe, the mechanics of hearing are the same, it's the perception of sound that is different.

This is ridiculous. Music wasn't recorded to listen like that. The sound would reach each ear at two different moments in time from both directions. Can you understand how bad that would sound? The sound from the right channel would reach your right ear and then pass to your left ear and the same thing would happen from the opposite direction. It would be as if listening in a tunnel. That doesn't happen with headphones. The idea sounds great on single malt scotch but it doesn't take an audiologist to figure out that it doesn't make sense.

Stereo is very different than two mono channels. You should read up on stereo microphone techniques.

While the OP is wrong in his conclusions, there is some truth in his thinking. If you position your speakers as he suggest you would minimize any crosstalk cancellation between the loudspeakers. This is something that Phase Linear/Carver did with their autocorrelator and Polk with their SDA loudspeakers.

If you want to experiment with the concept all you need to do is place absorptive material midway between your speakers and extend the material to the listening position. Your listening space is effectively bisected. Ideally the only sound that reaches your right ear is coming from the right loudspeaker with the same for the left ear/loudspeaker. I listened to a demo of this approach back in the early 90s and it did create a very convincing stereo image without the headphone like hole in the middle.

And even though I disagree with the OP what he suggests cost nothing to try. I further applaud the fact that he didn't label his idea the "Quantum Speaker Placement Theory".

Speaker placement is dictated by the room, not ones ears

When a recording engineer produces a stereo mix from the various tracks, he is attempting to simulate a performance coming from a stage. The sound reaching the ears of a listener in the audience does not come from the side, so the studio monitors are placed out in front of the engineer while he blends the tracks between the channels to simulate the way the sounds reach the ears at different times. In order to reproduce the sound the way it was mixed, it is necessary to set the speakers out in front like the studio monitors.

Placing speakers this way is second nature to us audiophiles, so it always shocks me when I see someone's speakers set up differently, for example, aimed at each other from opposite corners of the room.
