hi,
a have a lovely pair of coral beta 10 full range drivers,the problem is 1 of the drivers cloth surround has stiffened to the extent that ts affecting the speakers t/s measurements.
looking closely at the sealer used it would appear it is some sort of pva clear type sealer,i have tried a lot of solvants to remove this but it seems to be very stubborn,im going to try mek next.
any ideas?
Close
