Actually a major improvement can be seen with just 2 speakers. The extra speakers recreate more ambiance/reflections but is not necessary however he states if you want to extend the listening width from 110-120deg to 180 or even 360, you can do so by adding more and talks about how to do it.

RED-You should try it with the samples they have and then use foobar to play any of oyur normal listening music through the convolver with the impulse files.

Basically all this theory, is pretty much the EXACT opposite of how "stereo" (equilateral triangle) sound works but works with normal everyday recordings, unless it was all synthesized.

It has been done, but plenty of research continues to improve it. There are even consumer grade processors out there that have used an early form of this. Tact being one of them. I think Method B is based off the newest research.

Look at the figures on that page, a picture is worth a thousand words sometimes.

It basically takes binaural (normal human hearing)/(headphone listening) and externalizes to loudspeakers.
