Help Repairing Vintage Pioneer SE 205

[gamewizard]

So I got a pair of Pioneer SE 205's and the left driver has become detached in the housing, I examined them and the epoxy holding the driver  had finally dry rotted to where it could not hold the driver. What would be the best way to repair them? I plan on restoring the right side while I am doing the left so this does not happen again.
(Side not to the mods: if this is in the wrong section I am sorry feel free to move it.)

I'm not sure I understand. If the expose is no longer working, why not just reglue it with more epoxy?
