Dried up Ferrofluid?

Dried up Ferrofluid?

I posted this up 6 months ago, why some were complaining about harsh Thiel tweeters that get non-linear distortions with sticky old Ferro Fluid that’s gone like tar, it has to be cleaned out, just don't add new fluid to a gummed up voice coil gap, you'll be wasting time and effort  

A lot cheaper than buying new diaphragms. $10 for new fluid vs up to $200 each for new diaphragms, and they could be clones/fakes.
Still have to clean out the old fluid doing either.

Tweeter Ferro Fluid and how to change it.

If you can drill a pilot hole straight, and add glue you can build a kit.

Here's one of the simplest kits out there, get your hands dirty and then after you may not think it was all that difficult. :-)

Fun to do with your kids.

Hey there b-limo,
I went thru this with my Kef Reference 104/2's recently, so I thought I'd add my two cents' worth. First, kudos to you brave diy'ers, I hope you all succeed. I took my Kefs to a trusted repair guy and he told me the ferrofluid had dried up - then led me to Midwest Speaker Repair for a pair of new tweeters, which supposedly have specs close to the original, and some say sound better. They were $60 each, I had them installed and the sound is really good. (Had to also rebuild the woofers, common with this mid-80s model).

Contact Bill Legal at Miller Sound in PA if you want someone to do them for you,

Happy Listening.
