What are Your Favorite Tweeters?

I have experienced many things in my life, but this has redefined what a tweeter can do:Altec 288-16H a la naturelle.... (no horn attached, fire it up to the ceiling).

2Tesla alnico motor driving the diaphragm to less than 0,9mm at peak excursion. At 100dB/m volume the diaphragm moves only a few microns, giving absolutely distortion-free sound, while virtually all tweeters already are into very high distortion at this level. Also, you get that 100dB/m output from 42milliWatts of driving power! Leaving an 1W amp still massively oversized... hey, bring out your 0,5W amplifiers! :)

- Bohlender Graebener NEO3 planar-magnetic
- Magnepan Ribbon
- RTR ESL.
- Stax ESL
- Hell, any ESL (except perhaps Martin Logan)

VIFA. 

but, they could use a better crossover freq. 
   a bit bright, but,".so flawless, cymbals, voices, etc. 
they are nice.    Very open and have the Hall effect when listening at low volume, high volumes, they can be a bit of a molar gritting kind. 


    Whatever they are, the Energy RC-70 tweeters, and the rolled off highs about 600mhz, or Mghz, or whatever they are,.

the best smooth tweeter I’ve ever listened to.
    When the morons at Klipsch bought, and ruined the fine Energy brand, I’m glad the price dropped on the rc-70, bought 2 pair.     Too bad Klipsch destroyed Energy, they could have learned a thing or 7 from the engineers at Energy. 
I miss this brand.
   Heard those veritas 2.? Long time ago, they were something special.     My rc-70s’ are to me ,...perfect, no fatigue at all, always smooth, inviting, and I can listen for hours, low volume with Jeff beck, Gary Moore, the midrange is just made for acoustic guitar and voices so well!
    When jamming forbidden, or Kreator, deicide, megadeth, whatever, the treble is NEVER over right, ever. I love these speakers!

    The odyssey beryllium, is also amazing, airy, and not that bright, maybe a little on rock and metal, but maybe they are not meant for metal?

Also, when the patent ran out on those folded ribbon tweeters, that was awesome, they are a great tweeter.
the best ones I heard were on the Martin logan 40 and 60 series.

The big Scans-peak silk domes found in upper end Tektons make those speakers surprisingly good. 

I have 2 or 3 favourite tweeters, my 1st choice is Donald Trump

magnepan ribon tweeter (20.7)

and

Dynaudio esotar 3  

both pure heaven

Field coil is best if you can afford them

Seas Millenium

~~~~~~~~~~~~ Over rated as are all the others you mentioned, Dome tweets are garbage.
Go Compression TI Horn
Why? Horns have super high sensitivity = far superior sound vs dome tweets
or as highend666 says, *Field coil IF you have the $$$$$$$$$$$

Making a list asap.
