Has anyone here replaced the ferrofluid in the B&W ZZ9989 Tweeter (ZZ4723 Tweeter Assy)?
I recently purchased a set of CDM1 SE's and the tweeters are working well. Since these are around 25 years old I'm considering replacing the ferrofluid. I have read through this article ( https://www.speakerrepairshop.nl/in...eeter__zz09989___zz9989_&lang=en#.WyeuKfZFzIU ),
but have a few questions for someone that has actually done it:
1. Removing the diaphragm: The article says it is clamped on the magnet. Any tricks to taking it off, or any risk of breaking the diaphragm mounting plate which looks to be made of plastic.
2. Since my tweeters are working, I assume I don't need to replace the actual diaphragm dome and coil, correct?
Thanks for any tips or tricks in doing this.
