One of my microPAs uses JBL EVOi324 speakers with the (rotten) amp removed and driven by a regular amprack and DSP. I noticed one of them was sounding a bit unhappy recently in the top end. Pulling off the 2430 driver, I discovered flakes of the silvery material used to plate the neo magnet had migrated into the gap. Luckily the coil appears OK, but any attempt to tweez out these flakes results in them breaking up into smaller pieces. The double sided sticky tape trick doesn't seem to work either. Anyone struck this and found a good procedure for cleaning them out ?.
