    A second problem is that all magnets have a so called "Curie temperature", beyond which it fully demagnetizes ... forever.

    Alnico is beyond 450C , Ceramic 600/700 C , while NEO: pltry 100 something C.
    That 100C does seem like a puny figure for NEO compared to the Herculean 450C to 700C for other types. But is it really a practical limitation? Just to put it into terms Americans understand, 100C is the boiling temperature of water. I know I've never owned a speaker that ever got that hot for any reason. Considering the worst situations a speaker is likely to encounter, black car/sunny day, still air and hard use, etc. I can't think of anything that would have a beaker of water boiling next to the speaker. Of course the speaker itself heats, but the magnet never gets that hot. By the time it did the voice coil would be destroyed.
