Thanks Bob, very clear as usual.
It all depends ultimately on thousands of little digital transducers moving their adjacent air bi-directionally, all under control of highly reliable electronics. A key milestone for me was the claim of proof that these little transducers can complete many years of such cycles without physically deteriorating - provided the dust-proof membrane is equally reliable.
And your description of the complexity of the digital waveforms needed to generate crisp, clear volume and directionality of the sound pressure AP output to the analogue receiver nerve hairs in presumably highly variable human heads generates a deal of wonder that current speakers seem to do so well!
