Moving this from the classified section.  Although, the search for a spare pair still continues.

I removed the magnet assembly from the faulty driver, and was able to inspect the voice coil:

It looks OK.  No loose wires, corrosion or signs of excessive rubbing.
A DVM across the terminal yields a reading of approx. 90 ohms.

Could this be a poor solder joint between the flexible cables and the aluminium voice-coil wire?
