I just spoke with a guy who have made both permanent magnets and electro magnets for loudspeakers.
He said that the reason that electro magnetic speakers have a smoother and more grain free sound, is due to the temperature rise in the mechanical parts of the magnet, this sligtly changes the mechanical resonance characteristics of the magnet.
He even experimented with heating up a permanent magnet of a loudspeaker to the working temperature of the fieldcoil version and was thereby able to emulate the benefits of the latter.
So gentlemen, put a lit candle under your compression drivers.
