Hi there,

I am a rank amateur who inherited a pair of beautiful KEFs from my dad. One of the tweeters is out. It is a T33 8 ohm. Kef says they don't make these but can send me a diaphragm and I can repair it. Seems straightforward enough, though I'd have to get a friend with a soldering iron to do the leads.

Can anyone offer suggestions? I'd rather just replace the tweeter but there are none on eBay and none come up on Google. How do you even know it's the diaphragm? It seems fine but now that I have taken it apart, I am bound to proceed.

Any wisdom greatly appreciated.

Jennifer

Have you tried connecting the tweeter to a benign audio source like a transistor radio or ipod via a 3.5mm jack to two bare wires.

Sound, tweeter ok, so the problem lies elsewhere.



To repair the T33 you remove the four screws holding the faceplate and thread the wires through it.

The dome/voice coil is held by double sided sticky tape, KEF will advise on how to remove the residues.

The new dome will have protective paper over the sticky bit and all you have to do is get the two holes aligned with the two lugs on the top plate.

How much is KEF charging for the redome?

I'm interested as a "spare" has had the attentions of a dog's claw so the dome is holed.

At ~£28 that's competitive with the items of unknown provenance you see on ePrey, so I’d go for it.

If you have any watchmaker, surgeon or dentist friends, their steady hands might prove useful, best of luck Very Happy .
