"Comparative Studies on the Behavior of Beryllium, Titanium, and CN Fiber Hybrid Dome in the Last Octave," by Oberton engineer Peyu Vlaevski. For some years, Oberton has been conducting efforts in the development of a new composite fiber diaphragm, combining a low relative weight and a high damping factor as in beryllium, with mechanical characteristics similar to titanium. The result lead the respected Bulgarian loudspeaker manufacturer to perfect a composite diaphragm material, combined with a suspension for the diaphragm periphery based on carbon fiber (CN fiber). This article details how this carbon composite dome - already implemented in Oberton's latest ND72CN and ND100 compression drivers, behaves compared with other 4" compression drivers that use beryllium and titanium diaphragms.
