Needed replacement diaphragms for a pair of 4333B's. Ordered official JBL replacements. One could not be installed due to a poorly made voice coil and former. When I compared the replacement diaphragm to the old originals, made in March of 1980, it became obvious that the quality was very poor in comparison. The new ones said "Made in Mexico". Does anyone know of a good quality replacement, because the JBL's that I received are pretty much unusable?
Regards,
John
