Foxman Posted July 3, 2020 Share Posted July 3, 2020 I've got a pair of 1982 Heresy's with K22-E woofers. One of them has some white spots on them. It is purely aesthetic and does not impact the performance of the speaker, but it is noticeable. What would a fellow do to replace that driver? I have googled around a bit, but the information I found was old. Any thoughts on the best solution for the person who can't live with these spots? Does anyone have one sitting around perchance?

jimjimbo Posted July 3, 2020 Share Posted July 3, 2020 Take a soft cloth, dampen with a white vinegar solution, and lightly wipe to see if they come off. Otherwise, put the grills on and forget about it. No need to replace the driver. 1 Quote Link to comment Share on other sites More sharing options...

I'll try the vinegar, but a key part of the detail I left off is, I am trying to sell them and the buyer doesn't want them with the spots. Maybe the vinegar will do the trick.

jimjimbo Posted July 3, 2020 Share Posted July 3, 2020 I would gently vacuum first with a brush attachment, then the cloth. 1 Quote Link to comment Share on other sites More sharing options...
