Comparative Studies on the Behavior of Beryllium, Titanium, and CN Fiber Hybrid Dome in the Last Octave

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 article details the comparative study that took place directly within the research conducted by the famous loudspeaker manufacturer from Bulgaria. This article was originally published in Voice Coil, May 2020.

In this very strong edition of Voice Coil, focused on up-to-date topics for loudspeaker professionals, we discuss the industry's Asian supply chain, how a new carbon composite dome compares with Beryllium and Titanium products, and James Croft reviews a recent electrostatic loudspeaker (ESL) patent. Vance Dickason focuses his attention on two innovations coming from Eminence, in two extreme product categories. The new Eminence NSW4018-8 18" Tour Grade Woofer, and the new N314X 1.4" compression driver, which is the first to use TeXtreme composite material for the diaphragm. Download your copy now!
