I restored a 1959, made in England, Metropolitan Nash car radio. The 4X6 speaker had a rubbing issue that I got rid of and the speaker is listenable but very low fidelity. So for fun, I hooked the radio up to another 4X6 speaker from a junked German radio. There was a tear in that cone and a bunch of holes like from a pencil point. Nevertheless, it sounded incredible! Just like a brand new car radio! I found a similar speaker at Parts Express that might fit but the owner is looking into sending it out for a recone. I gave him a guy's name that I used for myself once and he did a good job. He doesn't just replace the cone. Do the conditions in a car take a toll on the speaker? I've never had an old radio speaker sound as flat as this one.

A closed vehicle can easily reach 120F for many hours in the summer. The atmosphere can be condensing as well as less than 20% humidity in the winter. there will be fumes as well. A conventional cone will last 3 to 5 years with a foam surround. A pleated paper surround will last a little longer. Sometimes insects get hungry too... A conventional cone could be treated, but as noticed, suffered in the fidelity. Any speaker will sound better installed into it's baffle...
BTW, be sure the re-coner can do oval cones...
YMMV
