How much magnetism is required to disrupt a stereo speaker?

Um, uh... "hypothetical" physics question involving magnetism or electromagnetism to disrupt a stereo speaker... you might
be a little entertained. Or not.

A simple stereo speaker, maybe ten cubic inches, is on one side of a typical (2x4 studs and plates/drywall) wall. Directly opposite it, on the other side of the wall, might be situated a large magnet (hung there permanently) or (for a few moments) even a simple homemade (large bolt or screw wrapped in wire that runs to a battery or, in the case of extreme bravery and some good research, a wall outlet -- yes, I know you'll advise against the latter) electromagnet. How big of a magnet or electromagnet would be required to disrupt permanently the magnets in the stereo speaker (which causes the wall to vibrate like a massive speaker bass chamber and is extremely annoying) ?
Disruptive non-magnetic ideas are welcome as well.
Um, uh... thanks. ;-)
