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. -- Mike Hughes Lofty Pursuits (Public Access for Rapid City SD USA) bigtex!loft386!mhughes
