We describe the development , manufacture and testing of a new large format compression driver diaphragm using a beryllium dome and new type of polymer surround that exhibits improved performance . This design promises to give long life and good reliability with little or no change in performance anticipated over the life of the diaphragm. A comprehensive set of tests of Beryllium, Aluminum and Titanium diaphragm compression drivers is described including frequency response, distortion and wavelet time domain analysis on a 2 inch plane wave tube. Substantial differences were measured in the performance categories, particularly in the frequency range above 4 kHz.
