Problem with AER-MD3 (BD-Design)

Hi Bert,

One of the AER-MD3 drivers I bought from you about ten years ago to use in my Ortis 150 horns has developed a serious problem. After eliminating other possibilities and listening carefully I am pretty sure the problem is a misaligned scrubbing voice coil or perhaps some foreign matter in the gap.

An obvious solution is to ship the driver back to AER for repairs, but I am hoping you can suggest a more simple plan that doesn't involve intercontinental shipping. Any and all suggestions you might be able to offer to me will be very much appreciated.
