Thanks a lot!
Can be that you have info on tweeter that was originally fitted in Roksan Ojan 3? This is that what I really looking for.
(Asked about Roksan Darius just because they have similar tweeter with one from Roksan Ojan 3 if I am not wrong 🙂)
Who can upload the user manual of first version (images post #1) ?
And what other loudspeaker manufacturers uses this cage stand version ?
this URL don't provide the wanted information.

I have the original Darius in cages with MK1 crossover dating from around 1986. I can provide a circuit diagram. It's a simple Single-Pole crossover and the speakers are very good. Revealing, stable image, require a good source.
Later incarnations of the crossover were apparently improved.
I'm in the process of activating them. Manfred Baier of Omtec built an active crossover for his own use - Bessel function, phase linear, 24 or 36dB slope I think - but I haven't been able to track down Manfred or his crossover.
If anyone has a later crossover @itsme5k, I'd be very interested in a circuit diagram or a closer look at it.

Concerning the used tweeter is the question, with or without Ferrofluid.
According the sound impression of a friend, who have purchase it in used condition, I guess without ferrofluid. Then the predecessors from one of this tweeters probably in use:
