Hi all.
Is there anything that's applied to speaker cones to make them less frail?
I'm working on a set now that the speaker cone feels like onion skin and cracks with the lightest of touch.
Thanks,
Carlos

Other folks have done this:

It all depends on the actual condition of your cone. Partial repairs and reinforcements are ok as long as the material used is not too thick. If the reinforcement applied is too thick or stiff, sound quality would suffer.

Thanks AJJ.
Good link.
