Hi there,

I recently came across a pair of second hand Kef C60 speakers, only fall back is that one of the tweeters is significantly dull in comparison to the other.

I have switched the tweeter between the pair to confirm that it is only the tweeter and not the cross over.

I am rather new to Hi-Fi and was wondering if someone here might be able to give me some advice on what could be causing this problem and if a repair is worth it or if it would be a case of replacing the tweeters.

The SP1210 contains a material called Ferrofluid, which enhances the power handling of the unit by dissipating the heat from the vioce coil. Over time this fluid irreversibly turns into a jelly and finally a wax.

A firm in Chicago (I never knew the name), used to be able to rebuild T33mkII's, but if you cannot find them, the unit need to be replaced with either another T33mkII or a brighter current Uni-Q tweeter R1548X for which you'll have to find a method of fixing to the original faceplate.
