Richard, if you determine it's a speaker problem I've had luck with spraying the cone lightly with water then lay it face down to dry. It allows the voice coil to center itself. If that works then I put a coat of contact cement on the outer edge of the cone where it flexes. The cement will dry flexible and bond the paper fibers. Result is a little more bass response. Give it shot, nothing to lose. BTW, anyone know why the tubes are upside-down?
