What are Your Favorite Tweeters?


Hi All.  I would like to extend the survey that occurred back in 2008-2012 about favorite tweeter types.  During that survey, folks mentioned: Gallo CDT, various ribbon tweeters (RAAL, Kapton, Legacy), Fostex, Dynaudio Esotar, Heil, Seas Millenium, and various exotics (electrostatic, plasma, compression driver).  I am wondering about ring tweeters, such as the Satori TW29R or the Scanspeak Revelator. I am (personally) looking for something that can fit into a 104mm diameter lip.  But for the big picture, I'd like to know what tweeters you have loved!  I've got Accuton diamond tweeters in my Avalon Eidelons, and I think they are quite delicate and natural sounding.

The horn loaded titaniums in my Heresy IIIs...previously the aluminum-magnesiums in my Silverline Preludes.
 
I was impressed by the Zylon material used on the Yamaha NS5000 tweeter. However, my impression could be a product of the complete speaker package because the mid-range and the 12 inch woofer are also made from Zylon.

I am also a big fan of the driver in the RAAL SR1a "earspeakers". I do not consider them headphones because they do not sound like headphones but 2 channel speakers. The detail out of that driver is incredible.
Speakermaster,

The t 35 is a nice tweeter. A local builder finds those and uses them in current project.  Another vintage tweeter that he uses is the Jensen RP302.  I particularly liked an open baffle system he built with a Jensen M10 fieldcoil fullrange driver and an RP 302 tweeter.  But, I am sure the field coil Western Electric 597 tweeter would be a substantial, albeit very expensive, upgrade.  This is sort of a dream system for me, although I do not like the inconvenience of having to turn on and adjust power supplies to speakers.  
The AirBlade from Arya Audio Labs are truely amazing in terms of speed, music and bandwidth
