Any personal opinions on SS D3004/6640 (Beryllium)?

Anyone has anything to say about the sonic character of SS D3004/6640 (Beryllium dome)?
Besides them being ridiculously overpriced?
One can get a pair of Yamaha NS-1000M for that money, with beryllium tweeters and mids...
Or could it be that it's the sweetest and smoothest tweeter of them all?

Hi, I have a pair with me but am in the process of getting the enclosure built. I've been using Scanspeak drivers for a long time, and none have let me down. Will update with listening impressions in a few weeks time.

Cool, I saw your thread, would be nice to hear about your impressions!

You're tempting me to put a small 6uF cap in series and "hear" the tweeter!

You bet!
I donno what chlorofille is up to, meanwhile I purchased the tweeters and built the speakers... Gotta say, I like em!

Very nice speakers, and a nice big chamfer too

That said, I'd rather have a RAAL 140-15d than this scanspeak.

Yeah well, it's all maater of taste I suppose - I had the RAALs and thought that, like all ribbons, they sounded somewhat uninteresting. I suppose I only like dome tweeters...

Hi guys, it's been a while since I have posted here. I have built my 2 way speaker with the D3004 Beryllium and AT 15H C-Quenze, and have to say this is the finest tweeter I have heard in a system. Sibilance in certain recordings sounds very natural and never harsh. It does not get your attention like the R2904, nor does it have the dispersion of the D2904 but together with the 15H midbass, female vocals were stunning. To sum up, it has the "speed" of the finest ribbon tweeters, but with extra richness and an utterly non fatiguing sound. I found no trace whatsoever of any "metal" sound.

I have it crossed at 2500Hz, 2nd order electrical, though lower crossover points are possible due to the extremely low distortion.

Excellent tweeter!
