Seas Excel Diamond tweeter or Plasma?

Thanks for the post. I actually already own my designer’s former top line speaker (Tetra 606) that has the Mundorf dipole AMT in a rear horn configuration. For sure they disappear and create exceptional “sound”. We are hoping to make something that is superior. My guy wants to make a 4 way with a smaller woofer on top. His plan is to create a sound similar to a duel concentric point source. He is a master with crossovers. Interesting that we have decided on an enclosure shaped like a baby grand piano. Slanted back to time align with beveled edges. He is confident that he can make it sing.
Another friend involved in the design also is against plasma. 

You'd better check with Kenjit before building anything.

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.
