Regulars here will know I'm VERY BIG on Graphene.
This stuff will revolutionize audio transducers if not in a couple years, than certainly in a decade or so.
Here is some food for thought.
After reading the main article, several links at the bottom of the page provide further material to mull over.
If this stuff can be fabricated in 2' wide sheets, AND doped with a conductor, making a Magnepan style transducer a fraction of the weight of current models will be EASY. That buys sensitivity and better frequency response. It should be possible to make a graphene RIBBON which will outlast a dozen conventional ribbons, have better HF response, higher sensitivity and render all other such designs obsolete. A folded style, like the HEIL AMT would be EASY and have a similar edge over the same driver today.

As I recall, when discovered/made several years ago, it was one of those curious things that chemists came across, not sure of what applications it would have. Uses were pursued after the fact -- it was not developed to filll any particular need, but it was one of those things that tingled engineers' spider-senses.

Thanks for the post. As a crass materialist, I enjoy these things. One atom thick. Can you visualize that?

It went from a laborotory curiousity to a researchable material fairly quickly.

Scientists and engineers KNEW this stuff was hot if it could be made into useful shapes.

Loudspeaker manufacturer Magico has been exploring the use of graphene in their drivers. Whether or not they've implemented it yet, I don't know.

But which composite to use for cabinets?, posted on January 9, 2017 at 07:56:21

In lieu of Baltic birch plywood?

I'll check that out. 'Mixing some in' doesn't count. I'm waiting for a PURE GRAPHENE ribbon or planar.

2x layers of PLYBOO. It comes in 3/4" thickness so 1 1/2" will work fine.

Have the SHARPEST TOOLING you can obtain and maintain. Bamboo has a High Silica Content and really chews thru tooling. Even Carbide.

Graphene by the Board Foot will be a dream material for QUITE a while.

Yes they have.
I googled 'magico graphene' and got a advert page.
They use it in a midrange driver of the S7 model. The claim of lower weight and higher stiffness are consistent with what you'd expect, given this high performance material.

OK. Their Operations Manager told me about a year ago, but I didn't remember if he said they were planning to use it or if they were already using it. I heard the S7s in their room, and they were terrific sounding speakers. See my post in the "Magico" thread in the Speakers asylum.
