Did the presenter say how many chips were used to produce this line? Was this for 1, 4, 16, 64, 80 chips? Any recollections of how this was presented or any commentary that explained what they were saying?

If I recall correctly the former use of the graph showed what SPL measurement a single Phase 3 chip was delivering (as shown). From what they have said elsewhere this is also likely to describe the output of a single chip, which indicates a large increase in sound output. But it could be from the 4 chip demonstrator, which is still good. But if it represents the 80 chip unit that is a big difference and quite significant.
