I am afraid it might be blown, from the sounds it was making while it was hooked up. Is there an easy way to tell if the voice coil is blown? Could the deterioration of the surround cause it to make the buzzing sound?
Eminence Speakers is right up the road from me in Eminence, Ky. They manufacure a lot of speakers used for musical amps and PA systems. I'm going to try to contact them and see if they can help me out.
Thanks for the response!
