Which Tweeter preferred- dome natural material, Beryllium/Metal or Planar Ribbon? Why?

@jperry

It really depends upon the execution of the design and integration in the speaker as a whole.

I'd say so too.

The best tweeter is one that does not draw attention to itself.

I’ve heard some cheap tweeters that didn’t and some expensive ones that did.

The worst case was the Seas Excel which introduced a very odd colouration to John Lennon’s voice on Across the Universe.

Before anyone gets upset, I acknowledge that it’s an great tweeter, almost everyone says so, but in this design, despite the high level of resolution it offered, it was drawing attention to itself.

Custom satellite grade carbon fiber dome integrated into bespoke Scanspeak frame / motor matched to .25 db the pair, had tuned w filter network in anechoic chamber to match the reference. No breakup modes from midrange filter and 30 kHz.

I enjoyed my Seas tweeters in my audio physic speakers.  After a move to a basement system instead of a joist supported floor, went to Martin logan montis.  I found the hi frequencies detailed without fatigue, yet missed the air movements produced by conventional drivers.  Present pleasure is compression horn in Fyne audio.    Still have the ml in ht

Got beat to the punch, but agree carbon fiber is the way to go. ;-)

Musadd- Funny  you should land on the sealed planar ribbon tweeters 

as your flavor. I find the Borresen speakers to be the best sound I've

heard- and by a pretty good margin. 

Danger-Danger!- Nelson Pass loves to tell the story about his Plasma

speakers which nearly killed him.
