are MT225 or the Mitsubishi Alnico version still in production?
Hi, I just read this query now so forgive the delay. These (Matsu) tweeters have not been produced in a few decades and I'm unaware that any are still being produced. I highly doubt it though. Alnico magnets are just too expensive to produce, especially for what would widely be considered a "mass market" tweeter. It's performance is outstanding no matter what label gets hung on it.
I'm the only guy in the world who offered them as NOS (or otherwise I think) but don't offer them anymore. Maybe I'll incorporate them as part of a finished product someday.

Supravox would be able, to re-introduce such a cone-tweeter. There are a lot of alnico versions (2000 series, also not appropriate for the mass marked).

There are undoubtedly several manufacturers out there who could make an alnico drive paper cone tweeter but I don't see why they would go to the trouble unless the niche hi-fi marketplace called for it. Like elliptical drivers, cone tweeters seem to have stigma attached to them irrespective of their potential performance.

about the URLs
FRS 5 X - 8 Ohm
TW 70 - 8 Ohm
TW 6 NG - 8 Ohm
you will find several Visaton datasheets (FRS5X, TW70 and TW6NG) of cone tweeters. The largest disadvantage here is the absense of a large magnet system for high sensitivity (neodymium) like by this version:
http://www.scan-speak.dk/datasheet/pdf/r2904-700000.pdf

Where are cone paper tweeters with heavy ferrite or neodym magnet systems for very high efficiency (at best 100db/1W/1m) ??

Thank you for your advices

in this case also this URLs are of interest:
WLM Stella clone
Does anyone know of a good paper tweeter?
