Don, good question! I'm not an expert on ferrofluid, but I would believe yes, it can dry out just sealed in a plastic bag. The ferrofluid comes hermetically sealed in a small pouch, similar to what you get catchup and mustard in. The pouch needs to be cut open to get the fluid out. If you were to buy new tweeters, I would still take the half hour to clean out the old fluid and install fresh fluid. Best to not be penny wise and pound foolish! There may be additive packs of chemicals in the ferrofluid we are not aware of that can off gas into the atmosphere, including a plastic bag......Lou
Kef Reference Tweeters-Ferrofluid Replacement
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.
Take care,
Lou
