Seas Excel Diamond tweeter or Plasma?


Interested in building a speaker using, I think, the most expensive “conventional” tweeter available at $6k a pair for the Seas Diamond. I only want to use the best drivers available. TAD 15” woofer, ATC dome midrange and a great tweeter.
I well appreciate the art/science of speaker design working with an established Speaker designer.
Surely the enclosure and crossovers are critical. I lean toward the Diamond but not sure if the Plasma is better.

LoL 😂😂.

oh man, that was a good one.  Impeccable timing.

I’m sure the op already knows that they need to be custom tunes to his ears
fuzztone,
Careful invoking his name!
It's like saying 'Beetlejuice' three times....

There's really only a tiny bit on the Seas Diamond tweeter.  I have used the Seas Excel Beryllium tweeter and that is just excellent.  Much cheaper at $1400 a pair.  Although, I really like the B&W 800 series with their diamond tweeters.
The little I have heard about the Seas Excel is that there is none better.
A least it seems that it may be the hardest material in a dome. So the fastest? And the back is sealed and in a diamond cut... kind of. It looks very cool and the front as well. Price certainly does not always reflect quality. But Seas is a super established and great quality company. It seems that they made the Excel at the lowest price point possible. 
Oh, Kenjit, Kenjit, Kenjit!
Pretty much like Beatlejuice!
But I do admire his chutzpah!
He also has a way with words even if very obnoxious!
Do I require the "Kenjit stamp of approval?'. I HOPE NOT.
But I do kid of miss him.
Do you think he is a complete put on?
