As was stated above it depends mainly on the surrounds. If foam then less than 10 years same for butyl rubber and the like. I inherited some 1959 JBLs which work fine, however they use fabric surrounds and compression horns. You need to take that sock off unless some one knows what type of surrounds you have. Most used foam or rubber by then. Therefore I would recommend getting them remounted.
