Looking for SEAS midrange driver

Hi

Last weekend I noticed issues with two midrange drivers on my Visonik concept 7 speakers.
There are four of them and two of them, both the upper driver of left/right channel makes a scraping noise (sometimes, under specific conditions). I think the voice coil might be deformed.

I think these are SEAS Excel drivers, but I don't find sufficient information on replacements or where to buy them.
Is anyone here able to help me identifiy these?

Greetings!
