ghdprentice - AMT 1D’s have Poly cones that don’t disintegrate and the rubber surrounds are pretty durable, but can be replaced.
Paper cones and various other cone materials are also durable unless they have been exposed to direct sunlight and heat. It does depend on the speakers, but my main system uses Altec’s. I still also have some full-size ESS Heil in the guest suite. Both are 70’s vintage and excellent. I would have the crossover capacitors replaced with high grade modern caps.
