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.
I was collaborating with audio engineer a few years ago who has been setting up
quite elaborate arrays of speakers arranged to direct sound in particular
directions, they have done fit-outs in the local state parliament chamber, and
actually achieved nice clear announcements confined to the appropriate platform
in a train station with 25 platforms. A nice system, from reasonably priced
components.
