    You have no way unless you de-magnetize it!

    People have tried other techniques, but the correct method is to demagnetize the driver and then disassemble, reassemble and then remagnetize the driver.

    I had Speaker Proís do exactly that on a 2440 with a broken throat for me, this month. $55.00 USD plus shipping.

    They did a very good job.

    If we knew what the hell we were doing, we wouldn't call it research would we.

    The guys that came from Orange County Speaker Repair in CA.

    A note of small consequence, I supplied the throat. They donít have those.

    Once you break the circuit of a Alnico magnet it will loose half it's magnetism. When put back together the driver will be about 6db down from normal.
