Diamond dome tweeters

I’m not a fan of the overall sound of B&W speakers, but I have to say I was impressed with the tweeter in the 804 and 802D3. I can’t seem to ever warm up to most metal-dome tweets that almost always grate on me at some level, but I got none of that with their diamond tweet. I personally think Usher crushes B&W on every level and also make their own drivers, so I’m finding myself very interested in hearing their newer speakers with both a diamond tweeter AND midrange drivers.

The Seas Excel motors are a whole other caliber of driver vs. the B&W.  Two other diamond dome makers I know of are Jantzen (not sure if in production) and Accuton.  I trust Troels ears a great deal, and he described the Jantzen diamond tweets like I describe the Mundorf AMTs so...

Oh, I think Crystal Cable made speakers using the Seas diamond, and JA at Stereophile did an absolute crap job reviewing it.

That the tweeter is flat to 600 hz is impressive, but for what a $35,000 pair of 2 ways? The diamond dust deposit usher does is completely different than this seas excel. I'm starting to think the engineers at seas are running out of ideas.

This was the only Seas Diamond reference I found:

I have used several Seas drivers.  They are very nice with different sonic signatures.  I build and then re-built a set of speakers for a project (2 towers and a center).  For the last rebuild, I considered using the Seas diamond, but at $6k per pair, they were just too expensive.  I ended up using the Seas Excel T29B001 Beryllium, which were excellent!

those are $6k each sold in pairs!!! tell me i'm wrong, please
