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.
