magnets and speakers

Dearest /tech/,

Will a strong magnet affect the output of the average speaker? Googling 'speaker' and 'magnet' turns up things the speaker magnet might screw up, but not the other way around.

*IN* the cone I can probably avoid. Beside the cone is what I was worried about. I'm thinking about mounting an LCD television to an in-wall entertainment center with an articulating arm. I was hoping I could put little magnetic tabs on the outside edges to keep it snugged up to the wall. It was magnets or velcro, the latter of which I'd rather not do.
