Hello folks,

my Name is Micha, I am from Germany and unfortunately don't speak a single word bulgarian, but I am glad that I made it into your forum through the language barrier

I have pair of rather large superb quality active 3-Way Nivox Studio Monitors Model 4 that should have been made in Sofia (perhaps), one of them is not working and I am desperately looking for a circuit diagram or some useful info about Nivox itself, adress, email, if they are still producing etc.

Would be really nice if someone can help me, regards, Micha

Hello!

Thanks for your reply, but they are different than the above mentioned, I will add some pictures, maybe someone will recognize them.
(Even though, the specifications you posted sound familiar, but different crossover frequencies etc.)

I have seen similar speakers in Technical University of Sofia a few years ago
But I don't know anything about them, except they have (at least) two different versions. They are extremely rare.
Try asking here:
