Beryllium is a rare chemical element with very low mass, very high tensile strength and remarkable thermal stability. It is incredibly rigid - yet lightweight; everything an audio speaker diaphragm needs.
Manufacturing raw Beryllium ore into finished material is a challenging process. Truextent metallurgy manufactures pure Beryllium foil with a highly uniform grain structure; this is many times stiffer, yet far less dense, than more common cone materials. In industry testing, our Beryllium cone material exhibits substantial improvements in durability, speed, and reduced interference. It adds more than an octave of distortion-free output.
In the Paradigm's Persona B, matched Beryllium drivers reveal the full range of high performance. Persona B is the only loudspeaker in its class to utilize Beryllium material for both bass/midrange and tweeter drivers.
