Electrostatic speakers do not have magnets, but they have to be quite large to
have any base response.  They are also very expensive and require high-voltage
power supplys.  The MagnaPlaner brand of speaker is not electrostatic and does
have magnets.  Piezo tweeters don't have magnets, but most of those I have seen
reproduce only very high frequencies.

I think you must get the things away from the compass!  You might consider
free standing speakers which could be hung on brackets.  This would also let
you get them out of the weather.  I'm not sure any worthwhile speakers can
really stand to live in the cockpit.

I just leave the hatch open and keep the stereo below.
