Not many companies do produce high-end, cost � no � object, compression drivers for domestic use with the most advanced techniques and best materials , for the most demanding users in mind.

What parts and materials would a most advanced compression driver use ?

Diamond diaphragma:

http://www.kinik.com/KINIK/products/newproducts_dd_en.asp

Keronite diaphrgama :

Keronite has developed a unique form of Plasma Electrolytic Oxidation (PEO), a chrome-free process which transforms the surface of light alloys such as aluminium and magnesium into a dense, hard ceramic with outstanding resistance to corrosion and wear.

Beryllium diaphragma :

Or possibly plutonium....

As far as hard diaphragms go, diamond is impossible to beat. Single crystal diamond cannot be produced in practical diaphragm sizes AFAIK, so we have to go with polycrystalline forms. One promising technology is UNCD, though regular PCD is overkill for compression drivers anyway.

Pure silver wire for a field coil (otherwise neo for permanent magnet flux), Permendur/Hiperco 50A for the magnetic circuit for maximum saturation induction. Nanocrystalline alloys like HITPERM may in the future allow for a similar maximum saturation induction but with a much higher electrical resistivity to attenuate eddy currents.

  the bigest diameter kinik has of their diamond diaphram is 32mm. that limits it's use for high-frequency drivers only. do you know any company wich is utilising their diaphragms ? i know only accuton using diamond, and it seem they produce them on their own, someone i know that heard them said their drivers do not sound good.
Believe it or not, there are also gold diaphragms - Christopher Witmer 06:52:46 07/14/07 (0)
I have heard that some of the Japanese high-end compression driver guys have started to use GOLD in diaphragms. I was shocked when I heard that, because to me it seems highly counter-intuitive. But apparently there are genuine sonic benefits, or at least they believed so. You can probably guess where the benefits might be coming from, if they are really there at all and not just people barking up the wrong tree and all excited because they managed to convince themselves of something that isn't true. Such things can happen, at least temporarily . . .
