Seas Excel Diamond tweeter or Plasma?

I have to say that overall I've never heard a tweeter actually better than the Mundorf AMTs. 

I've heard crappy AMTs and I've heard great dome/ring radiators and people I respect say the Beyma is as good or better, but never have I personally heard any speaker with a better sounding tweeter.

Point to that is, I have no desire for exotics for the sake of being exotic.

I'd sure like to hear them. 6 thousand dollars. I want to hear them.

I'm real happy with a couple of combos I use.  I mean REAL happy.

6K, got to be something to hear.. Are the domes plated with diamond?
Or made of diamond? 

A single pair of drivers for 6K. Makes my head twist like my dog when she hears a weird sound. Yup..

Regards

The plasma tweet is difficult to combine with ATC’s 75 unit -- mechanical compliance will be an issue, before even discussing electronic compatibility.If you wish to improve upon your Tetra, add low-frequency energy maybe even using a couple of 12-15" /channel in open baffle configuration. It will be a bear to cross, but you do say the designer is a master of crossovers.I would also play around with conventional tweeters, metallically coned rather than ceramic.

As a matter of curiosity, what’s wrong with your Tetra 606???

here's no best, there's a best for a specific application and intention.


I would agree with **There is no best,,,*

I've looked at every  SEAS tweet, and wondered if anyone actually employs the Seas Diamond. Most expensve= superior..? I am not convinced .
**Money no object*  may not result in *best ever speaker*. 
Makes sense to build on SEAS drivers only, as i've found SEAS makes the finest, most musical voice coils/cone material, magnet designs. 
Look if your customer wants a  speaker that is superior in musical reproduction,, 1st what is his source and then amplification power. 
A exceptional speaker, hooked up to a  avgerage sounding other components, may only result in just a avg speaker.
laying out that kind of money, synergy is critical. 
I am not convinced, expensive drivers = superior speaker. 
btw I also am interested in Mundorf's AMT Ribbon . But then keep in mind ribbons have that kooky characteristic of The Narrow Sweet Spot, Can't deal with that weakness. In order to have M's ribbon work, is a  row of 3, = $$$$$.
Keep us updated on the final design and give us a  test YT vid. 
We all want to see exotics in action. 

 I have no desire for exotics for the sake of being exotic.

What we are after is natural, uncolored, dynamics, nothing **warm**. 
Warm = coloration, murky lower midrange. 
Of all SEas mid tweets, the only 2 I am interested are the Thor's Millennium and tyheir *Flagship* Cresendo. 
The Millennium is a  incredible midtweet, natural,  voices the human voice with stunning realism. 
a 3 way witha  midrange, would upset this and add warmth, 
The upper midrange of the midwoofer meets perfectly the lower midrange registers of the Millennium, xing ,,, I think 1800hz
Here is a good discussion on xover points. 
To my ears a  3 way sounds blaring/dominate , mushy in the mids, Mids are 80%+ of the music. = a  more simple xover of midwoofer+midtweet is the ideal design for capturing clean, clear critical mid fq's. 
There is no need for a midrange in a  MTM design. 
Midtweet  = superior to   tweeter./midrage combo.
