Is anyone familiar with any diaphragm with voice coil diameter of 75.5mm or 2.972 inches? I am looking for such a phenolic type diaphragm for a pait of RCA drivers that I love so much but I am unable to find diaphragms and thought that some other drivers may use similar diaphragms.

Thanks for your answers in advance!
