The best tweeter design


Been giving some thought on the best tweeter design and I came up with the following list:

1) Plasma
2) Ribbon
3) Horn-loaded
4) Diamond dome
5) Ring radiator
6) Inverted dome

But since 1-3 are hard to implement or expensive most speakers start at #4, at best.

Thoughts?

Plus 10.... The Maggies suffer from poor x-over design, apogee did a much better job...

regards,
Weseixas, yes that is true. But a guy over at audioasylum who does extensive mods with Maggies (Peter Gunn), including entirely new crossover and new frame, still doesn't like the Maggies with the true ribbon tweeters because of integration issue. When I owned the Maggie IIIs, I was impressed by the high freq detail, but the kinda wore on me over time. Still, very fine speakers to this day. To me, proper integration of high freq with the rest of the lower freq is more important than a highly detailed airy tweeter that sings its own tune.

It's funny with all the new tweeter designs using the latest diamond, beryllium, ion, and ribbon materials, I still find a simple silk dome tweeter to be more natural and more enjoyable. We, as audiophiles, tend to jump on the "latest and greatest" band wagons as the only way to achieve high end sound (I'm also guilty sometimes), but experience has shown me (and like Stanwal and Johnk) over and over again implemenation trumps choice of the individual part.
Wesexias I have the Acapella plasma tweeter in my system, and a friend has a Lansche Corona plasma tweeter. IOW - I have heard both plasma tweeters which are currently in production.

If I had to pick a second best, I would nominate the Heil AMT (as used in Adam Tensor speakers) as a superb tweeter. Extended, uncoloured, free of any metallic sound, and natural.
Electrostat is the best form of tweeters I have ever heard. Better than ribbon or any such planar design.

Among the conventional tweeters, Esotar is the most revealing yet natural sounding tweeters I have come across.
