If that is true, then I guess the link I posted regarding CNMAT/MeyerSound "eigenspeaker" is bunk? I'm talking about a different configuration of ambisonics than the traditional speakers around the listener and the associated sweet spot. IMHO that's a somewhat difficult configuration, especially for mobile apps, so I was just wondering whether the effect be gained with only four speakers in a "polar" configuration. And if not four, six, eight, or how many? Can they be arranged in a "circle" around the perimeter or is 360 degree configuration of drivers required?
