Hi, this is an older thread that I need to revive. I hope it isn't considered Hi-jack!
I have a set of AMC model 12 speakers which I have unfortunately done in to a degree. I tested a sine wav thru them and it sounded square. So I took the grills off and the cones, foam are all fine. So I believe the 'coils' are bad. Something behind that actual cone. I unscrewed the driver (woofer) and it was stuck in there with some putty. I wonder if the wires burnt out... But there is a metal box with almost cloth sides (thick) and I wonder if this is where the coil is hidden.
I know nothing of vintage speakers and want to fix these. I feel stupid for ruining them but what can you do.
Anyone out there have some knowledge of these wonderful speakers? They seriously have sounded great in the past and I want to restore them. I think the mids, tweeter as well might be blown. One speaker is more intact than the other too, but both are compromised.
AMC model 12 baby!
thanks
