I have been reserching 15in woofers, everyone makes them now with neodymium magnets! JBL, as well as others! There are a few different models, including JBL, that interest me.
My question for today is neo,s reliability! A few guys I have spoken to, sound contractors, have told me to stay away from neodymium magnet woofers because the magnets have a habit of becoming completely discharged if overheated! I knew this was in fact a problem with neo several years ago, and neo was only really used for compression drivers etc! But now every manufacturer has seemingly high performance, and lightweight woofer models available featuring neo magnets, so whats the real deal? Is neo a reliable magnet in a high power woofer, in commercial use?
An enquiring mind needs to know!
