With CVD diamond and alpha corundum ceramics we have already two of the very best membrane materials on earth, so why search for a new one?
The largest ceramic dome, which we are able to produce without suffering of any loss of quality has a maximum diameter of 160 mm. It is used for example for our C220- series. The diameter of our diamond dome is even at a significant distance smaller. By doing research for larger bass cones we found some interesting results.
