What are Your Favorite Tweeters?

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

Focal (JM Lab) - Their inverted dome tweeter.  

I have a pair of JM Lab Mezzo Utopia speakers, which uses a single front firing inverted dome tweeter, and the extension, detail, and smooth sound is very catching.  I also have a pair of Von Schweikert VR-6 speakers, and these use a pair of these Focal inverted dome tweeters, one firing forward, and another in a dipole configuration that fires to the rear to create an ambient affect.  My VR-6 speakers are heavenly.  Their airyness, extension, smooth non-fatiguing sound, and large soundstage is simply fantastic.  

Beside my Mezzo's are a set of VR-4 SR Mk III using the Dynaudio silk dome tweeter, I think.  Oh Lordy!  These silk domes, while not as detailed and fine sounding as the Focal inverted domes, they are also very smooth, non-fatiguing, and have such a great airy and expansive soundstage - love these a great deal.  

Electrostatic for sure.   Better, full range.

+1 for inverted dome beryllium tweeter !
