    A friend of mine has an old Avatar cabinet, 212. Anyway, he gets litterally no sound out of it suddenly. It didnt make a pop or anything, just one day it quit all together. We replaced the crossover on it, but it still seems to be dead. Does anyone have a reasoning with this?

    PS. No because of an active bass, or a bad head, my Glock sound fine through the head, it is something with the cabinet.

    If you are lucky, it is a loose connection. Assuming the drivers are wired in parallel, you would have to blow both of them, and I think he would have noticed when the first one went. So it's more likely the drivers are OK. It might just be a matter of carefully pulling one of the drivers and taking a look inside.

    Probl;em has been found I do think.

    I popped out the speakers, one looks fine, the other, well, it looks like someone took a blow torch to it. Here are some pictures. Would this cause both of the speakers to completely not work, or would this possibly be the only problem.

    Also, how would something like this happen? A Bad Head? A Bad Crossover?

    Thanks for your help guys.

    That driver is toast, from being seriously overpowered. It's a safe bet that the other also has a fried voice coil, even if it's not obviously damaged.

    Your friend should call Dave at Avatar, he'll probably give him a deal on a couple of 12" speakers, or he might even warranty them if the cab isn't very old.
