Hard Audio - Ceramic Speakers

The Marten speakers used to be thst way very neutral a bit too cool, ,but they changed the crossover parts I believe to Mundorf s best Silver Gold oil
That changed their sonic voice to much richer and involving 
The crossover is the Heart of the speaker..

From what I read on DIY sites the B&W diamond tweeter isn't considered anywhere near the same class as the Accuton or Seas diamond tweeter.

Yikes, at $7,100/pair for the Seas or $3,700/pair for the Accutons, those had better be something amazing.  Given that most of us can't hear much beyond 14khz or so once we're nearing 40, I think I'll take a pass on those.

FWIW I did think the Accuton ceramic midrange sounded excellent on the Salk Song3As.  Salk is using another fancy midrange in the Song3 Encores, a magnesium cone with a bunch of holes drilled into it and some sort of (polymer I believe) backing made by Eton, which didn't sound bad, but the room those were in at Axpona wasn't set up as well as the room with the Song3As, so probably not a fair comparison.  

Hi Erik,

I´ve heared a couple of speakers using Accuton ceramic and diamond
chassis.

It seems to me, that especially the cross-overs are essential for a
natural sound.

A few companies are really producing bad, harsh and unnaturally
sounding speakers (to my ears) using (Accuton) ceramic chassis.
Marten, Gauder and Raidho were not bad. The only company which
produces speakers which are able to "sing musically" (to my ears)
is Tidal Audio.

Diamond tweeters like the one in B&W measure equally well compared to the Excel Millenium soft dome. So world class. Extremely delicate.

Don’t know much about the diamond midrange. Diamond is usually half a human hair in thickness. It might be very fragile if overdriven. Diamond is in a different league from ceramic. It is so rigid that any internal resonance may be entirely outside the audible band.
