Marine-type speakers are generally shielded (as are speakers intended

I'd be interested in hearing of any cases where a magnetically shielded
speaker has interfered with magnetic compass readings.

Something I always wondered about is, "How do you magnetically shield
something."
Doesn't Magnetism pretty much go through things. How could you shield
a speaker's magnet so it wouldn't affect a compass?
