    OK - i know that if you push (gently) on the interior of the cone and you feel/hear a crunch/squish it's a good indication of a blown speaker, THAT does not happen.

    What also doesn't happen is the speaker reacting in any way to a toner put on the terminals AND a 'zero' reading when attempting to read the ohmage with a multimeter!!!!

    The speaker is completetly dead with no indication of damage whatsoever. It was bought with a cabinet brand new 3 years ago. It was wired for 4/8/16 ohm per the input selector. Marshall type. One day the ouput of the cabinet changes in mid-song drastically - i was running two amps at 8 ohms apiece into either side. I opened up the cab and started tetsing each speaker with a meter and a toner individually and this is where I'm at. Three speakers that test fine audibly and per meter reading (15-16 ohms) and one dead.

    #1 - what's the problem?
    #2 - can it be fixed?
    #3 - is it worth it?

    The voice coil is probably open and needs to be re-coned. You have to do a price check on re-cone vs a new speaker. That's my guess.

    #1 Blown
    #2 Yes
    #3 About $75 to recone plus shipping. Cheaper than buying a brand new Greenback.

    are recones reliable? Drawbacks, aside from a compromised speaker?

    Is it a RI? You can find used ones for less than the recone.

    That's kind of what I thought.

    Thanks.
