Car Speaker Diaphragms Disintegrating
I have had a pair of Jensen speakers in my car for
about 15 years but they did not get very much activity in that time. The diaphragms have 3 sections - the inner one that looks like a low mound and is about 1" diameter. - the middle one of about 3" diameter that the mound seems to sit on - the outer one that is about 4" diameter maximum and is glued to the middle one. The inner two appear to be made from a thin brown cardboard and are in excellent condition. The outer one has a ridge in the middle that runs all the way around. It appears to be made from a dark green paper and is disintegrating. This green annulus is much worse on one speaker than the other. Is there any way to repair these or are the speakers just throw-aways? TIA |

It sounds like you're describing the surround, which is usually a rubber material that allows the cone to move freely within the frame. Were these speakers in the rear deck? Rubber surrounds are prone to environmental disintegration over time. Especially when exposed to sunlight for long periods. A re-cone might be possible, but would probably cost more than a new pair. Just spring for new ones. HTH Mack |
