Definitely
looks like a Heil AMT.
I remember seeing these in a German diy e-shop; you could hopefully find info there... Now if I could only remember the shop  (maybe a search with heil a.m.t. + .de would help) |

They certainly appear to be Heil AMT's, (Air Motion Transformer), and they are considered among the best tweeters/upper midranges in the world. I auditioned them once in a stereo shop in the seventies-it was hard to tell because I didn't think the woofer in the ESS unit was all that great.
Do a search for Heil and you will see that this has been discussed often. There is even a member named AMT-freak! Here a couple of discussions on the Heil: Air Motion Transformers (Heil's) and New Diaphragms The Diaphragm Goddess from Heil Ess driver?

Lucky you, those are AMT 1, selling at about 1000 € per pair. The European distributor is Audio Int'l in Frankfurt, but I am not sure if they have a web site. www.hifisound.de carry their products also.

These are indeed fine tweeters. ChrisB and i are working on a design using these for a client (pictures are from a developmental stage -- i hope to get pics of finished speaker this week) and previously did a 3-way AMT-1 conversion. dave

With the tendency of the surrounds on AMT1 woofs & PRs to disintegrate you will occasionally find an entire speaker at a steal. A friend in dmonton scored some AMT1s with these Ts for $10 CAD.
