The best tweeter on the market right now is the MPD tweeter in the monitor audio platinum they go to 100,000 clean no other tweeter whether it's dome or ribbon can come close to the performance of this tweeter
What speaker has the best tweeter?
I love the AMT tweeters in my speakers. They are definitely different from other tweeters I have heard. I enjoy their openness and air. But there are qualities of other tweeters that excel in other ways. Some v pricy speakers use beryllium or diamond or diamond coated beryllium. I see that the price of, Seas I think, diamond tweeter is like $6K a pair. Then ribbons offer used. Not to mention plasma, etc.
