Default Peerless K040MRF mf driver replacement

Any suggestions where I can get a replacement for a Peerless K040MRF medium frequency driver or what drivers I could use in place of a damaged unit. It looks like this.

I can't find one on Ebay in the UK. It is in a Pro9TL Mk2 cabinet and has failed completely. This thing has a sort of a can on the back of it so doesn't depend on an enclosure which makes replacement difficult.

Not sure I am competent to repair a speaker but thanks for the link.
How well do you think the Celestion HF1300 would work as a replacement? It doesn't have an open back, it is supposed to be a medium frequency driver and it seems to appear on Ebay quite often. Obviously I would buy and fit one in place of each of the Peerless K040MRF drivers.

THe HF1300 is a tweeter rather than a midrange unit that you seek .
From memory it wants to crossover at about 3kHz at least .
Probably about 10 times high er than you need
Aside from probably not working very well at all , you'd probably blow the HF1300

ie : don't do it!!!


Is there some info re equivalents for this unit based on Gale GS401 rebuilds
maybe try the new surrounds first - what have you got to lose?

Monacor SPH-135/AD can make a quite good replacement. It would need an enclosure, though.

SPH-135/AD

Or you can send your broken Peerlesse to recone at the address above.

If the surrounds are the only problem, then just send them to be professionally fitted with new surrounds. It's a no-brainer.

From the depths of the WWW:
"The Peerless 821615 units are a Wilmslow Audio recommended replacement for the original Peerless KO4MRF units that failed some ten years ago."

& (very!) alternatively : It would require massive recalculation of the XO, but there are other vintage sealed mids of the same general size. I'm thinking of the Coral ones (e.g. 5M-12) that came with their own enclosure. Look for Coral kit speakers, such as the 12SA-1, 10SA-1, and so on ...
