Hi all
I need the specs of KEF Type SP1092 speaker coming from CODA III B200 unit. Actually I am looking for replacement as the coil started rubbing the magnet. Except of that speakers sound still great at high levels. Wondering what could be a cause... maybe rust (?)
Many thanks
Raf

Take out the offending bass unit, mark the upside of the magnet with an indelible marker, then turn it 90 degrees. Usually fixes it. The spider and surround sags, I expect.

I don't know for sure who made the paper bass, possibly Elac, but it's a common model found in a lot of old designs. Like the Monitor Audio R352.

I'd think this will work well enough as a replacement:
80W 8in Shielded Bass Mid Range Speaker | Maplin

I'd need to see the crossover to suggest any more. But you can adjust tweeter level with a ceramic resistor or two.

It looks like I found the issue You can see little bubbles of air inside of paper tube.. however the coil is in good condition. I think the speaker was overload.
