Material & Fabrication Ceramic

Alpha corundum or saphire is one of the best material choices for speaker cones. It is light, yet very stiff and if it is made by the electrochemical process we have invented in the 80’s of last century, it also has a quite nice internal damping factor, all that a speaker membrane is supposed to have.
