  2. Cobalt Magnet Subwoofer

    Technical & Advanced Car Audio Discussion
    I haven't heard of a cobalt magnet subwoofer. I think Alpine made some mids from cobalt magnets, but that is about all I have seen. Is there such a thing as a cobalt magnet subwoofer? Might be shooting in the dark here, but curious if anyone had ever heard of one. If so, it would weigh a lot...
