Greetings!
I am restoring an old speaker from England - a Mordaunt Short Signifer. circa 1980.
I am looking for a replacement tweeter/s. The original is described as an Isophon 25mm soft dome, and there have been references to this being some sort of Isophon KK10/8 possibly but that is not verified. Have reached out to Lockwood in England - but they no longer have the spares.
I was hoping someone would know of or have you come across a possible replacement for this tweeter, or where some stock of it might still be available?
One tweeter is not making any sound, but the mid and bottom end are excellent, and soundstage and transparency are very very good. Wide and easy soundstage. Timbe of piano and guitar and voice are well reproduced even with one tweeter MIA.
Any other information would be welcome.
Many many thanks

These tweeters pop up on ebay quite frequently. The KK10 has a few OE variations and the dome asy is generally the same with the only issue being the integration with the faceplate. This tweeter isn't very extended on the top end and has a warm character. I'd keep my eyes peeled for a replacement on the European ebay site. I'd also verify the filter cap in the crossover is ok. They did use electrolytic caps in these speakers and they've been known to become leaky, allowing lower frequencies to pass. The KK10 used a paper or fiber VC former which is much less tolerant to higher volume levels than aluminum or kapton.
