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.

Hi Charlie !
Im aware of course of directional loudspeakers that use ultrasonic beating
- but I understood this is able to position sounds in 3D space - without
physically having to point the speaker - if so that would be quite a cool

also it seems to be suggesting it can project sounds to precise points in
space, at different distances from the speaker - in a way that someone
breaking the beam wouldnt necessarily hear it (as they do in normal
directional speaker sin museums etc) - thats the bit Im skeptical about....

From their website :

“The sound pressure at the ultrasonic focal points is sufficiently high to
radiate audible sound based on the self-demodulation effect in air.
Consequently, the ultrasonic focal points act as audible sound sources.
This sound-point method enables us to control aerial audio distributions
more flexibly and more precisely in comparison with conventional
superdirectional (sound-beam) loudspeakers.”
