In pursuit of a semi DIY horn project I am tempted by some bass speakers, one of which has a 'rubbing voice coil'. What does this mean and is it likely to be irrepairable?

very hard to stop ...its often due to a distortion of the coil caused by overheating ie the units probabley had it imo
 
depending on the units, they may well be rebuildable.
It's possible to strip the driver down and reuse everything with a new coil.
it does depend on what they are though!
 
Some coils come on formers that are easily swapped out, others aren't. it could be the spider that is skewed, that's an easier fix, typically. Or they could have been badly reconed, which is another relatively easy fix.

More details please
 
Driver identity

Thanks for all your efforts.
The driver in question is the standard Klipsch 15 inch bass driver from the Heritage range (Khorn in this case).
