Ann: Preliminary Final Report, page-60

One of the key reasons why hifi enthusiasts pay top dollar is due to the accuracy of sound reproduction. AKP's speakers excel at that. No doubt there'll still be companies like Gucci who will design speakers with AKP tech, stick a few diamonds on them and charge tens of thousands for them

Of course roadies will still be required for plugging components together, setting up stages, lighting etc. Given the modular design and the optional highly directional sound output configuration, concert applications would be possible and actually desirable from a noise pollution perspective for nearby residents.
