FINALLY - Revel Performa Series 3

Diamond tweeters? Diamonds are stones... very hard stones...

The goal for a dynamic tweeter is to use a very stiff and very light tweeter that responds quickly without ANY
cone or dome distortion.

So HOW does coating a dome or whatever with bits of stone make that dome both VERY stiff AND very light? The adhesive would be the limiting factror, not the bits of stone.

Or are they machining diamonds into cones or domes?

I understand how Magnepan gains a dynamic response advantage by changing from 1 mil Mylar to 0.5 mil Mylar for their diaphragms.

So please be specific.

I would like to know this technology as well....this is all I can find for now:


Why use diamond for tweeter domes? It may seem extravagant, but the move is simply an extension of Bowers & Wilkins’s pursuit of the perfect loudspeaker. One element of our quest for the best is the development of drive units that neither add nor subtract from the signal. In a tweeter, that means creating a dome that remains rigid, exhibiting perfectly piston-like behaviour, as far up the frequency scale as possible. Best for this are materials with a high stiffness to density ratio - which is where diamond comes in.

I find it interesting that B&W raised their prices that much when they switched to the diamond tweeter, but the Usher BE718 only went from $2795 to $2999 when they made the switch. This was also the reason my local HiFi shop dropped B&W. Nobody was buying the diamond tweeter price increase and they were either buying Paradigm Studio series or Sonus Faber.
