I have a few M&K 250THX subs in my system. On the bottom sub of both speakers, the magnets that are used to magnetically shield the speakers, came off from the opposing magnet that is connected to the speaker. They used a foam material between the two opposing magnets with some kind of adhesive that has worn off over the years. What do you guys suggest I try and use to get them back on?

What do you guys suggest I try and use to get them back on?Glue. Double-sided adhesive foam is available, too.

But if you don't need the shielding, I wouldn't worry about it.
