The magnets inside any speaker are way too far away, and too weak to worry about. Irregardless of the worrying Hifihvn is doing. LOL! trust me.

OK Elizabeth. Here's the opposite that can happen. If you put some steel, or other ferric metal in front of the tweeter, the magnet may pull the object into it. This happened to a friend who put an amp cover in front of his speaker, and that was the end of the tweeter. Some Mission or others have the tweeter at the bottom. And no, that wasn't me with the cover damaging the tweeter *yet*. I guess I need a bow tie. LOL :)
