The question, is it possible to have a torus shaped > sweet spot for the audience surrounding the "EigenSpeaker" ? Such speakers do exist, Ircam in Paris has done quite some research on them. They are based on AMB theory, but they do not provide AMB playback - what you get is a speaker that can generate multiple steerable beams. It's used in acoustic measurements to excite just part of a space, and in EA music to simulate the directivity of real instruments.
