Is it okay if anything gets on the magnet of your subwoofer. I bought a 15" X.X.X and it came with an allen wrench stuck to the magnet. Can this harm it?
Lol. No, it's fine. I guess the only thing that could happen would to have a very large and powerful magnet re-arrange the poles on the sub magnet. That would probably fuzz some stuff up. But other than that highly unlikely situation, you don't have to worry about stuff sticking to it.
