Ring radiator tweeters - the future?

Greetings,
I am using the ring radiator tweeter with my Sonus Faber Cremona's and must say it is one of the better tweeters I have heard. The other is the ion plasma tweeter usded in Acapella Speakers from Germany in which I had a chance to listen to recently. Be very careful about listening to either of these tweeters because once listened too, the listener is wrecked for life in listening to anything else.

They are being used on the new VSA 5se.

Aren't ribbon speakers the true promised land of sound quality? Just that ribbon speaker are terribly inefficient and bulky?

I hope Ring radiator tweeters aren't the future. Since I don't use tweeters at all. LOL

Infact I never plan to use them again, unless my upper frequency hearing gets so bad to where I have no choice but to bump up the dBs in this area.

Look at where the heart of music is on this chart. I've discovered myself some tweeters add artificiality to the music in certain cases.

Musical Instrument Range Chart . If your speakers can't get this part of the frequency range right. Who cares about a tweeter?

Try the (relatively) inexpensive Polk LSi speakers with this tweeters, and put 3 times the price speakers to shame...there are a few threads on this great speaker on A'Gon, check it out....truly one of the undergroung gems in audio, exceptional for the money. Don't snob yourself out of trying it just because of the Polk name, it really is a nice integration of the Ring radiator tweeter, and it's a nice-looking speaker to boot.
