Diamond Tweeter?

[davef]

Hi David,

Since you entertained the idea of a diamond tweeter, have you ever entertained the idea of a diamond woofer? I believe the Raidho D-series uses one. It seems like you get the speed/impulse response of a high end metal driver like beryllium, but with all the positives of a non-metal driver like better damping.

I figure if you are going to go with a diamond tweeter, you would also want an equally fast woofer to keep up with the tweeter. Or heck, even just go the Raidho route by combining a ribbon with a diamond woofer.

I don't see how a diamond woofer cone is even possible to manufacture and the cost, even if possible, would be astronomical. It also would not be a good choice of material for a woofer cone.

I think Raidho is just capitalizing on the term "Diamond" by vapor depositing an extremely thin layer of some form of diamond coating onto a carbon fiber woofer cone. Not really sure how this offers any performance advantages. Reminds me of when companies were mass producing Be tweeters by using the same process, the truth eventually came out - with most of them utilizing less than 3% Be.
