Remarkably easy.
Removing tne old ferrofluid with some masking tape run around in the coil gap.
Clean the gap with masking tape and isopropyl alcahol (20% diluted).
Clean coil with cotton buds and iso alchahol again.
Refilling with ferrofluid was a doddle as well as with tne magnetism it goes into tne gap a treet.
Lots of different types and ratings of ferrofluid.
But if you search the net, should find a site detailing which one to use.
I found this on a site selling ferrofluids, tnen bought much cheaper off ebay.
The coil assembly was held onto the magnet with double sided sticky tape.
To seperate, run a knife around and ease off.
Careful not to insert knife too far and damage coil.
If you damage tne double sided tape, just buy some of wilkos own brand, cut a ring out of that.
Remove tne old tape and use tne new ring.
Only neccesary if you damage the old tape as i did.
This was for T33 tweeters.
No idea if the tweeters in the one’s are similar.
For the kef 104/2 removing and reinstallng tne tweeters was also simple, as kef used push on connectors, so no soldering.
Good luck.
