Avalon ,discoloration of ceramic tweeter

You burnt the living #$%&* out of them, Best to get the exact tweeters from the distributor and pop in two new ones. Just be careful to attach the wires correctly. I did the same thing but no color chage to my JM/Focals. The fix was very easy but not exactly cheap - and I am not a DIY guy, yet anyway.

Do / did you play them very loudly?

I also own the Avalon Opus, and I do not play them loud. My pair have a light ring of discoloration around the center of the tweeter, so I called Avalon. I was told that the discoloration is generally normal and not a problem.

Basically it comes from a small amount of ferrofluid coming in contact with the ceramic through the gap of the voice coil. If you can hear a problem in the tweeter, or you cant hear the tweeter then you can have them replaced, but tech support at Avalon said they have received tweeters back that were almost completely black in the center that still played and measured correctly.

Thanks for the responces.

I have never played them loud.
Bought the Avalons used , with 6 months warranty (ended in May).
The dutch importer did listen to the tweeter, and it was sounding fine .
His explanation is similar to Aljordan`s.

If you look at one of my systempictures you see a new 30 mm new thiel tweeter with s slight coloration this one came straight new out of the box and plays fine
