From all the information that is available it is clear that the speakers do not "vibrate at ultrasonic frequencies". The pixel elements move from in to out position at a switching speed that is in the ultrasonic region. They switch on command from the ASIC to contribute a pulse of air movement, in or out, that is choreographed into the wavefront of whatever frequencies are called for by the composite audio signal. If they were to switch constantly i.e. oscillate at their natural resonant frequency, yes, they would generate an ultrasonic sound, but that is not what they normally do. I suggest you watch the videos on the AP website.

Thanks for setting me straight, BobF.

It would be great for investors if we could get an updated presentation at some point.

We have been told the speakers can operate from 20 to 20khz and, importantly, that THD is almost immeasurable. The team are working on improving the performance. What more might they be aiming for? A flat frequency response? +/- 0.5 db? Are there any other crucial parameters?
