What are the differences in Tweeter materials?

@Timlub,

Thanks for your post. My favorite soft domes have been from Dynaudio, Morel, and ScanSpeak. I find a lot of todays Seas soft dome tweeters to sound a bit on the bright side. I was not happy when Spendor switched from ScanSpeak to Seas for their tweeters. Especially in their Classic line. They always used ScanSpeak. I have a pair of Proacs that also uses the 3/4 inch ScanSpeak. Great tweeter. Wonder if they are still in business or did they get bought out by Peerless?

Mezzanine,

I'm glad you posted. My comment about the secret pricing structure, I hope, was taken just as some light hearted humour, and nothing more. Someone always seems to be complaining and/or joking about the high cost of some equipment, I just couldn't resist.

Unless I misread your post, it looked like you were trying to compare some of the more common materials to some of the more rare/exotic ones, with an emphasis on soft tweeters. API (Audio Products International), the parent company of several Canadian high end speaker manufacturers (Mirage, Energy, Paradigm, PSB and Athena are the ones I can remember. There may be others as well), make camel hair tweeters. They put them in Energy speakers and I think the original Mirage M series. I know several people that have these tweeters and swear by them. I'm not sure if they are currently going into any speakers but I'm pretty sure you can still buy the raw drivers.

Mezzanine, the Dyn and ScanSpeak tweeters are both very good, the few Morels that I have used had very good response curves and used at the right frequencies are excellent, not as detailed as they could be, but I have also found the Morels to have high HD that is very audible when crossed low.

What about magnésium. And the musicality..?

How about Accuton ceramic tweets?
