Diamond drivers


Out of curiosity I was wondering why diamond speaker units seem to be on the rise. Brands like Marten Design and B&W and many more are selling speakers with diamon tweeters. So what does make a diamond tweeter so good? Or is it just marketing hype. Although I doubt Janzen en Accuton are just making diamond tweeters for marketing reasons.

Yesterday evening I spend two and a half hours listening to the new Raidho D-1 speakers, they use a ribbon tweeter and a diamond mid/bass unit. I have to say this is the best monitor speaker I have ever heard. It is also a 17.000euro monitor speaker so for that price it better be very good.

Phusis, I understand about dull speakers, which speakers do you think are NOT dull?

Phusis, I understand about dull speakers, which speakers do you think are NOT dull?

As in "NOT dull" = real life vitality? None, presumably, and yet; fortunately what mimics real life sonic conditions do not require for an absolute replica, but works within thresholds where approximations of a certain order make for startling realism. It's just that many if not most typical hifi-speakers linger on the wrong side of the threshold that translates into "NOT dull," as I hear it. My own speakers, and their sibling models, are certainly not dull, as aren't many other alternatives fitted with compression drivers or (to a lesser extent) even tweeter domes in front of larger waveguides/horns - like all models I've heard from S.P. Tech/Aether Audio, various DIY solutions, JBL K2's and Everest, and others.

It's not only a matter of most notable compression drivers used in front of waveguides, typically used from 800Hz to 1kHz and upwards to 18-20kHz with 1" exits, but also very important is the bass/mid driver where such are not low fs units as typically seen in smaller 2-way hifi-speakers, where even 6 1/2" mid/woofers can get relatively sluggish in their upper working areas. A 12" mid/bass unit with a lighter paper cone and strong motor can make small wonders in the lower to central mids, I tell you, leaving smaller hifi-units pale in comparison, and moreover makes for a more ideal energy coherence transition in conjunction with a 12" waveguide than what you'd see between a 6" unit and a 1" dome tweeter or even a ribbon-like unit used in the Raidho's.

Phusis, the C1.1 are suppose to be significantly more dynamic and more emotionally connecting to the music than the C1. So may have gotten what you're looking for in the C1.1 that C1 was lacking. Roy Gregory have compared both side by side, and that was his conclusion.

Thanks for the recommendation and link(have read Mr. Gregory's review already, but still..). I've been wanting to hear the C1.1's for some time now, but haven't got around to it yet; I don't regard myself as a serious, potential C1.1 buyer, and therefore have left it for the chance to show itself for a more "informal" listening session. Gregory's review is promising though, but I suspect, at least judged by his initial and very favorable review of the C1.0's, that his inclination towards the hifi-ish sound would leave out trademarks in the overall sonic nature of the C1.1's too severe for me to overlook. We'll see, but I'm sceptical...
Phusis, may be you should skip the C1.1 and have a listen to the new Raidho D1 with the diamond mid/bass driver. Dynamics are supposed to be significantly increased over the C1.1.
