Paradigm Persona 7F Floorstanding Front Speaker Pair Blue

99.9% Pure Beryllium

Can luxury be a value? We believe so. One of the keys to Persona's luxury and value is our use of beryllium.

Beryllium is the absolute best diaphragm material, and Persona features Truextent® pure beryllium foil, specially formulated to be exponentially stiffer and significantly lighter than other premium diaphragm materials. It delivers superior transient response, virtually transparent performance, and audibly low coloration. Plus, it's a material typically found only in much more expensive speakers. Luxurious? Yes. But also a surprising performance value in Persona.

Beryllium: Welcome to the cult of high performance.

Beryllium is a rare chemical element (Be) with low mass, high tensile strength, and high thermal stability. It is incredibly stiff and lightweight; everything an audio engineer wants in a speaker cone.

In fact, beryllium has been used in the audio industry since the 1970s. But because it is used only in the finest (and most expensive) audio equipment, it has retained a certain “cult” status.

Precise control of the Truextent manufacturing process produces pure beryllium foil with a highly uniform grain structure; this is many times stiffer, but much less dense, than most common cone materials. In industry tests, our beryllium cone material shows substantial improvements in durability, speed, and interference reduction. It can add more than an octave of distortion-free output.

In the Paradigm Persona, tandem-matched beryllium drivers reveal the full range of high performance. Persona is the only speaker in its class to use beryllium material for both the midrange and tweeter drivers.

All models in the Persona series feature dual Truextent beryllium driver systems, and each model achieves a truly unexpected level of high-resolution detail, depth and dynamics, thanks in part to rare and extraordinary beryllium.

Partnered with the NRC

Paradigm is a partner of Canada's renowned NRC in their ongoing quest to reveal the true nature of sound and human hearing. The results inform the design and performance specifications, resulting in a uniquely lifelike listening experience backed by solid science.
