Speakers also cause problems with the pictures on TV sets if they are too
close (the magnets pull on the electrons and cause the picture to smear).
Boston (and probably other manufacturers too) makes special speakers which
have magnetic shielding.  I think they use something called "mu metal".  I
don't know whether those speakers are sufficiently shielded to use on
boats.
