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 tweeter that impressed me the most was one that seemed to not be there at all--it was so smooth and unobtrusive and high frequencies were present without calling attention to their presence.  The tweeter is a G.I.P Laboratories reproduction of the Western Electric 597 tweeter (field coil compression tweeter with a horn).  It sounded at least as good as the original 597 tweeters that I've heard.  The big downside is that both original and G.I.P. reproductions are quite expensive.  I briefly heard the G.I.P. 9501 tweeter (original design, not a reproduction) that is based on the 597, but, it was in a custom built system that had not yet been properly tuned, so I cannot say if this tweeter is even better; it is certainly much more expensive at $60,000 for the pair.
The Boressen tweeter I have heard is from the small 2-way and is a ribbon tweeter. And yes it sounds amazing. Is there a way to buy
one for under $33K?
Does anyone have experience with ring tweeters?  Can you offer some impressions?
I quite liked the vifa ring tweeters on the polk lsi9...

Im a fan of ribbons, beryllium and soft domes.

monitor Audio Ribbon tweeters are nice!
I've used Morel and still do on QSO 808 and as a HF driver along with a UHF ribbon on a pair of RSIIbs. 

1. I've never blown one.

2. They (Morel) are one of the best Ring and Softdomes around... Good to over 22khz. 2500 to 22,000, NO sibilance like some planars/ribbons. Expensive though..
