First time poster - not sure if this is in the correct forum. :(
I have a pair of 10A's that I bought in college around 1979 or so, and recently noticed that one speaker does not reproduce any lower frequencies, and one of the bass drivers looks like it is "pulled in" (gasket around the cone is flat).
Is this a crossover problem? If so, can I fix it? If not, what else might be causing this?
Thanks for the help!
