Well, I posted a few days ago about my GK cabs and 1 speaker which was buzzing. I thought it was due to the voice coil lead rubbing on the cone as the speaker vibrates. As you can see by the pic, there is more to it than that. The braided wire lead is frayed where it goes through the cone. My question is this - can the dust cap be removed to allow this wire to be replaced and then re-installed?...or does this require a complete re-coning? I'm concerned this speaker will not match (cosmetically) the other speakers and will not sound the same as well. Any thoughts what a repair like this will entail?
