More snake oil?

Perhaps not snake oil.

In 1990 I spoke with Dan Healy before the Grateful Dead show at Sandstone, and he was lamenting that there had not been a real advance in speaker technology in many years.

Graphene drivers (and for that matter graphene dynamic mic diaphragms) would not be a bad idea, though it might not be revolutionary.

Remember how the use of "Rare Earth" magnets allowed Sony to increase output and decrease size and weight of their headphones in the early '80's and the Walkman became a thing!?

I see that one point touted for the Graphene products is that the lighter materials will improve battery life (energy efficiency)  - That's hip.

Not something you'd find in an 8 to 10" driver of your home stereo.  I'm likely wrong.

Their target market for what I saw does seem to be small devices.

But if you had an efficient enough process, you could make a larger transducer out of a large number of these, (any perfect square would work) 64 of them? 525 of them? 65536 of them?
