These have been around for a long time and they do work but there is a
sharp sweet spot and no bass at all of course...  and it's really only
stereo for the one person they are focused on but if the 3d imaging of the
original source is reasonable then the one listener will definitely hear
the 3d imaging that one can hear with two regular loudspeakers when they
are precisely in the originally prescribed sweet spot.  Therefore, you can
say that they technically do what they say they can do but that is less
than regular a good stereo speaker pair.  The main feature is that the
ultrasonic beating that the two drivers do which produces the audible sound
at the crosspoint is only audible for the one listener exactly in the
crosspoint and not audible to anyone else in the vicinity, which is a good
trick when it is desired.
