it was during their AGM presentation where they had slides on the performance to date (see slides below or attached). They obviously had the output for both frequency range and volume that could be produced and they stated that they would publish updates as soon as demos were completed.
They have told us many times that given this is groundbreaking sound they have delayed such demos until they themselves were happy with the quality of the sound produced. so we have had some demos so they should provide an update on the frequency range and volume capabilities of what was shown
I am hoping we have groundbreaking technology amd it could be life changing for a number of us but I would just appreciate like many others clear and regular communications from the management
