Do not use super glue, or you will royally screw up your drivers. Super Glue gives off gas fumes as it cures, which will deposit on your drivers. It looks like a white crystalline haze. Use a small amount of fast dry 2-part epoxy (preferably one made for metal, but the regular kind is OK). Don’t use too much. A very thin layer is all you need, applied with a needle or toothpick. Make sure you clean off any old dried glue residue before applying the new stuff.
