Has anyone lost a KEF tweeter?


Wednesday I had a beautiful sounding system and Thursday morning the right side was so much louder and the left side was muddy sounding. I switched interconnects.  I switched speaker cables. Then I pulled out a test disk and played a 10khz tone.  Yep the tweeter in my left KEF Reference 5 speaker isn’t working.  I called KEF USA and they told me to call a couple of places for service.  The first place hasn’t worked on speakers in 4 years and I’m not sure the second place had even heard of KEF. One thing the guy from KEF said, was that all the speaker cables are soldered on the Reference 5’s. I checked the wires on the back plate and they were fine. So it either the crossover (s) or the tweeter part of the UniQ.
 

Grrr!

Ask Kef if they will replace the uni-q. Or if out of warranty sell you one. The way these things are constructed, if the tweeter is gone, it will be very hard to replace just that part. When folks have blown their uni-q drivers on the q series or LS50, I’ve seen them get replacements of the whole unit directly from Kef by supplying a serial number of the speaker in question. One used to be able to just buy the drivers for diy but Kef put a stop to that about 8 years ago.

At for how to get it off, I am guessing it is front mounted and the trim ring is glued over the flange. Kef should be able to verify this.

Also, one should be able to test the crossover electronically with a meter to rule that out. Good luck.

@prighello ,

I bought them new 10/21, so I’m hoping to have them send me a new Uniq.

And how to get the old one out. The drivers have a five year warranty.

@jetter 

I’m with you. I’ll remove a few screws and un-solder and re-solder something and (I’m sure that’s more than a lot of people would do), but that’s about it. I’m also expecting (🤞) something more than lip service from them as well!

 

Now where is my silver solder???

I just had a thought.

Does anyone know if KEF speakers have a fuse in them?  This has become a really long weekend without tunes playin’ on the box. ☹️

no fuse in kef speakers. my original uniq reference 10 year clock was ticking so i ordered a pair from the us kef distributer and installed them myself. back then kef drilled the midrange magnet and used an extended pole piece on the back of the tweeter secured by a screw tight to the back of the mids magnet. mine were the R105/3 and the drivers were removed from the back of the faceplate.
