"I close this article with a clear recommendation for the ND4015Be. It is one of the VERY BEST large format compression drivers on the market. And another good thing to mention is the phase plug which ends just at the driver exit so the exit angle is almost zero or about a few degrees which leaves all possibilities to combined this driver with acoustic loading horns or faster opening wave guides.

18 Sound has published a nice video about the ND4015 series of drivers showing also plane wave tube measurements and animations of the construction:

« This is an amazing new flagship compression driver for Eighteen Sound. I suspect this compression driver will find its way into very high-end theater speakers and PA systems, where detail and timber at high volume levels is essential. Beryllium has an outstanding sound quality and excels at detail and definition, so making a compression driver diaphragm from this material has been highly successful (e.g., the JBL 435Be or the TAD TD-1401).
