One question I forgot to ask regarding layout of an ambisonic system.
Rather than deal with all the trouble of routing audio and placing
speakers at the periphery of the listening area, is it possible to
employ a concept similar to the
Eigenmike ( http://www.mhacoustics.com/mh_acoustics/Eigenmike_microphone_array.html
) but instead have an "EigenSpeaker" with 24 small full-range
speakers mounted on the surface of a sphere in the center of a large
room? Such a configuration would be easier to setup, because all the
connections and DSP/processing/amplifiers/speakers could be kept in a
central area. The question, is it possible to have a torus shaped
sweet spot for the audience surrounding the "EigenSpeaker" ?
