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?

So far one of the best I have seen is the new tweeter made by High Emotion Audio http://www.highemotionaudio.com.

It is high efficiency, very fast but smooth without brightness and extremely wide dispersion angles (120 degrees). It is also rear-firing and crosses over at about 2KHz. It surpasses any ribbon I've heard (for example the Raal) and ESLs. They have at least two patents on it as far as I know.

The only other tweeter that I have heard that is as fast (but much more limited dispersion angle) is the field-coil powered tweeter made by Classic Audio Loudspeakers.

Weseixas, Blkadr, yes the HEA tweeter *does* look like the old Linaeum, but if you have a closer look they have little in common except that they are both tweeters. The HEA tweeter is sort of like a ribbon tweeter in a horn configuration- That diaphragm you see in the photos is a flexible film, and curved in such a way that it is very efficient. I understand that the tweeter has to be padded down so the other drivers can keep up; its about 107-109db 1 watt.

Unlike a ribbon, its not beamy, and even though its really fast, its not bright. They will be at RMAF...
