Hi Razmika,
Please illuminate what evidence you have to substantiate the claim that the diamond layer applied to Raidho D-series mid/woofers amounts to marketing BS?
I hope IÂm wrong but the above comment has the look and feel of uninformed mudslinging to me.
To begin with, the diamond layer has nothing to do with vaporized carbon.
The process is made by a particle accelerator and has nothing to do with vapor deposits. The layer built by Raidho is structurally very close to pure diamond and is approximately 140 times harder than the ceramic material on their ceramic cones. Pure diamond would be 200 times harder. The fact that itÂs Âonly skin layers can be looked upon like building a composite sandwich material, using the incredible strength and hardness on the outside skin layers, separated by a softer and damped aluminum/ceramic core. This really has two major benefits that you just canÂt achieve with a solid diamond material the first is being stiffer and better damped for a much lower weight, second is the ability to use diamond on the bigger drivers. Raidho claim that the Diamond membrane has its resonance breakup above 20 KHz and the Ceramic driver is at 12.5 KHz which reportedly was already better than any other manufacturer.
More details can be found on RaidhoÂs D-Series CES 2013 press release. Suggest you have a read.
To your other point on AccutonÂs diamond domes  yes indeed Accutone have a small tweeter (not a woofer, like the Raidho D1 employs) which uses a different CVD process to apply the diamond.
Why youÂd apply diamond to a tweeter is open to much debate, but what we can be more certain of is that the Raidho ribbon has a weight which is approx. 1/30th of the Accuton diamond dome and because of that it has approximately 30 times more speed and micro resolution as the critical current required to make the diaphragm move is also 30 times less than any dome!
Little wonder then that audio reviewer after audio reviewer (Valin, Gregory, Thomas, Fritz, Kershaw et. al.) report the Raidho tweeter to have incredible resolution sans listener fatique.

BTW, the so called "diamond" woofer, is also a bit of marketing BS. You can vaporize carbon on just about anything. It is not very expensive, and at this level, not very effective. Definitely not to be confused with drivers like the Accuton diamond domes.
