It took me three months to build up the courage to replace the Ferrofluid oil in my Kef tweeters.
There were several good videos on the internet how to go through the process, one in particular out of Texas.
There were no videos or instructions which directly related to my specific speakers; Reference 3~2.
They are ~ 20 years old and I noticed that the highs were muddy and dull in the right speaker.
I run a Cardas Frequency Sweep record every 6 months or so. The tweeter issue was noticeable during this maintenance procedure.
No replacement speakers (tweeters) are available from Kef or anywhere on the internet, so one wrong move and the speaker system would be worthless. I felt like I was performing brain surgery.
First speaker took ~ 3 hours. Second about 30 minutes.
I am happy to announce that the 'oil change' was successful!
The speakers are back to full factory operating specifications.
I've attached a link with some photos below.
If anyone needs to perform this procedure I can help walk you through the process.
