What is the best model c diagphram material?

[12jslater]

I have a model c with a bad diagphram and I have access to a copper, mica and glass diagphram and I wanted to know which will sound the best?

Thanks,

Copper will sound the best with molded cylinders. Earlier reproducers intended to play brown wax used glass diaphragms.

does the same apply to model H 4 min reproducers? Is it still better on blue amberols etc? Thinking of rebuilding 2 of my H's.

I have never seen anything but a copper diaphragm used in a model H, so there's your answer!
