    LE14C Magnets

    I just got my R.Cobb foam kit and I am going to attempt to do my first re-foam. Will post later on that.

    I noticed on these that the magnets won't even hold a key to them. Is this a problem? If so what do I need to do? Thanks as always.

    The iron pot and motor topology are self shielding. Keys are also brass.

    Right....put a flashlight battery to the terminals and see if the cone jumps.

    The older alnico pots won't attract iron. The magnetic energy is at the voice coil gap. Very little, if none, outside the driver.
