I wonder if anyone ran into this. Two out of four woofers are not centered. Voice coil rubs badly in one and slightly in another one. There is no indication that woofers were re-foamed. Am I dealing with improperly centered spider or just surround? Spider does not seem to be detached as I’ve seen in Klipsch subwoofer drivers due to basket rusting. I was able to peel off the surround from the cone and can attempt to re-center using low frequency signal but would like to hear opinions on how to verify spider alignment first.
Thanks
