KEF 104/2 tweeters

Good afternoon everyone. I just picked up a pair of KEF 104/2 speakers on CL. They are fully functional and I currently have them integrated in my system (Parasound Halo preamp and Nakamichi PA-5 amp).  I am concerned about the tweeters (one is slightly dented) and the ferrofluid. I've read some DIY fluid advice and am contemplating doing the work.  However, I've also heard that these tweeters are not top quality.  I've considered replacing them all together with Morel MTD 30s buy I can't seem to find any.  I would like to find a direct fit so I don't have to retro fit anything. Not sure about other available tweeters.... Also, do you believe it's worth while to do the surrounds while I have it pulled apart. Or any other suggestions for how to rehab them?? Thank you much!

Thanks ljgerens.  Yes I did get the Midwest tweeters.  I will certainly let you know how they sound.  They should be a direct fit hopefully. Not sure if I will need to do some soldering... I've tried leaving the spikes in and I have yarded on them to try and pry it loose. To no avail.. I'm afraid.  Any other suggestions.? One thread stated the factory uses a bead of automotive blue sealant around the bottom panel.. 😒

I am not aware of any sealant on the bottom panel, but I have never removed mine. I believe there is a gasket on the panel or the cabinet itself which may have softened over time and caused the panel to stick.

"If you have to take them apart, flip the bottom for the top woofer 

The woofers in the 104/2 both work in the upwards firing position so no benefit from swapping them about.

I just recently bought a pair of these speakers in decent cosmetic condition. they’re the Bi-amp ones in Rosewood, the foam surrounds were supposed to have been done two years ago.
I didn’t hink they sounded bad at all when I listened to them in the guys workshop. Once installed at home they wiped the floor with my Mission 765’s. on much more listening i began to think that maybe there should be a little more "sparkle" in the music. It was all there just a little set back. I wondered if they were condidates for the ferrofluid refresh.
I ordered some fluid and did the job when it arrived after watching all I could on Utube.
Boy did they need doing. the were almost bone dry and gummed up.Not sure if the link to a shared pic from my google account will work.

Verdict is much better. that sparkle is now apparent more balanced and thankfully not too bright. I’m really pleased with these speakers, theyr’re so easy to listen to for decent periods. Not tiring like my missions were.
