beryllium vs diamond


Hi guys, today's technology has brought us a new type of tweeter made of diamond or beryllium. Do you know what are the strengths and weaknesses of diamond vs beryllium? Which one is the more expensive? Has today's dome tweeter better resolving power than the venerable electrostat? Jim Thiel once said that dynamic designs will be getting better all the time and will probably surpass electrostatic designs.

They do all that magical up/down, left/right, fore/back, beyond the boundaries imaging you claim only ESL’s can do. I’d say they do it better than any ESL
No they don’t, I’m very good friends with the owner of Audio Marketing (importer) that imports the Focals, and believe me, I’ve heard them many times with Nigel the owner when he asks me to listen to the new models, they can’t come close to what big ESL’s can do, not even the Grande Utopia could.
https://6moons.com/industryfeatures/superfi/1.jpg Nigel's on the right.

And with that synthesizer music, all you need is a good PA for that stuff. you can’t tell what’s real anyway, because nothing is.
FYI there’s no hi-jacking going on here, the OP bought up ESL’s in his very first post.!!!! get a grip.

Manners, Georgehifi.....it maketh the the man. Fine to disagree, less so to berate and belittle....
I usually have, but there's no such thing with kosst, many will tell you.

Cheers George 
same way that rock can beat everything but paper in the game rock, paper, scissors, match.

Yeah but I went "lizard spock" that beats them all.

I’ve heard enough ESLs and big membrane speakers to know what they sound like, and they all basically sound the same. They present a massive wall of hyper-detailed sound with no sense of space
So full of it, you have no idea, you just described horns.

Over many years of audio, ESL’s have given me the best imaging in both side to side, outside the speakers, and in depth perception. No dynamic I have heard even Wilson Alexia MkII has ever equaled them.


But they wouldn't hold up too long being fed a steady diet of, Daft Punk, Tool, and DCD
As for your band/music taste, it explains now so much why you are the way you are.  
The esteemed moderators have wisely deleted the insulting, mocking, and arrogant post directed at me above by kosst
That’s typical as when he’s on it he has no idea, is obnoxious, and full of it in more ways than one. The only cure is to put an AVO out on him

I love Maggies but they can not hold a candle to a big ESL.
Totally agree, and neither can any dynamic tweeter I’ve heard, the top Raven ribbon comes close, and the way out in front of all is a Plasma, preferably without horn loading.

Like I said 4 posts ago
" I was more referring to Yamaha anyway, many models 1000 1000m 1000x 2000 2000x were a hoax saying they were Beryllium, when they were just vapour deposited coatings over plastic domes."
I stand corrected on the Focal ones. http://www.hse.gov.uk/pubns/indg311.pdf
" repeated exposure to beryllium and beryllium compounds may cause cancer. This has not been proven to occur in humans, but employers are required to handle beryllium and its compounds as if they can cause cancer."

As for Diamond tweeters I can’t believe they are pure and not vapourized over some former..
Will they ever be as good as an electrostatic speaker?
And ESL's will never be as good as Plasma tweeters. I have a pair of Plasma MP-02's crossed over from my ESL panels.
You've never heard/seen highs "dance" in front of like fireflies you till you've experienced Plasma tweeters.
It's all about the "diaphragm mass" when it comes to producing the upper mids/highs, and a Plasma flame has no mass.

Oh, and georgehifi it is the mass of air moved per unit weight.
I'm not talking about the mass of air moved, which is also needed to give bass air pressure into a room which ESL's don't do well and why a dynamic bass driver is better down low.
I'm talking about the mass of "the diaphragm" being moved back and forward to "accurately follow" high frequencies at 5 to 20 thousand!!! times per second. Like I said it's all about "diaphragm mass" at these frequencies, and that's why Plasma's rule, because the flame has no mass. 
I am not sure what those are but they are not plasma speakers. To create a plasma you need some serious heat which requires serious power and an inert gas. Those things would melt.

You need to do some homework, they are Plasma, and one of the best.
There are pages on this German Plasma tweeter if you take the time to look.

Show the links then seeing your soooo animated about it.

beryllium vs diamond

I don’t want to burst everyone’s Beryllium/Diamond bubble
These are just "dust coatings" adhered over the top of main diaphragm (usually polyprop) to aid in stiffening, trouble is they add mass to it also. I found this out when I saw a scratch on the Beryllium and saw milky clear plastic underneath on a pair of Yamaha 1000X

The only one I know of that used pure Beryillium forged/spun cones was one Yamaha speaker, the impossible to find http://www.thevintageknob.org/yamaha-GF-1.html
All the other Yamaha’s were Beryllium deposited on polypropylene diaphragms.
