Hello,
I recently got given a pair of KEF 103 speakers, and it seems that on one of the pair, the tweeter seems very 'dull' sounding.
The tweeter is a SP1049

I have an average understanding of electronics, and i've checked all the capacitors etc with a multimeter.

Could anyone offer any advice on how to check if the tweeter is working or not, or, if it is a component problem.

The tweeter works, but is very dull, (in comparison with the other working speaker)

Could anyone also offer a suitable replacement for the speaker? (or replacement for both tweeters if necessary)

I hope someone here can help me out, and thanks offering such a great forum and website.

Yours sincerely

Guy Evans

P.s. If i pan the sound over to the blown speaker, and lower the volume of the 'working speaker' it seems to even out the difference, could it be possible that a capacitor has blown and is not suplying enough power for the broken speaker.

i hope this info may shine some more light on the cause of the problem

Thanks again if you can offer any help Wink

Measure the inductance or the resistance of the HF units. The lowest reading will probably be the faulty one.
Or why not just swap them over? If the fault follows you have found the faulty unit!

If one of the tweeters is partly short circuit then playing loud could be making the amplifier complain…
Checking capacitors with a multimeter will only show up the most basic faults.
Have you tried resoldering the connections on the crossover board?
