TruExtent Acoustic Beryllium

SPEAKER DOMES, CONES AND DIAPHRAGM ASSEMBLIES FOR SUPERIOR SOUND REPRODUCTION

Materion's Truextent® premium acoustic beryllium is used to make domes, cones and diaphragm assemblies for high-end loudspeakers and headphones. Recognized around the world by OEMs and ODMs, Truextent genuine beryllium creates superior acoustic parts for crystal-clear sound reproduction.

There is no other material like beryllium for loudspeakers and headphones. Beryllium's unique combination of high stiffness, low mass, and high damping enhances speakers and enables the highest definition audio.

Using beryllium for acoustic components eliminates audible ringing and distortion heard from traditional materials like titanium or aluminum. In high frequency drivers, our advanced acoustic parts are capable of reproducing sound beyond an extra octave of useable, non-resonant high-frequency energy.

We produce speaker domes with and without surround assemblies from our library of standard geometries. We offer custom fabricated speaker domes, custom speaker cones and domes for headphones and in-ear monitors, and BeX diaphragms for loudspeakers.

These products are available in a range of sizes suited for tweeters, HiFi midrange, woofers, compression drivers and high-end headphones.

HIGH CLARITY TRUEXTENT SPEAKER DOMES

We use a unique method to produce Truextent beryllium material. Beryllium metal is rolled into a thin foil, creating a highly uniform grain structure, unlike physical vapor deposition (PVD) acoustic beryllium components. Our rolled beryllium foil has increased durability when compared to PVD.

TRUEXTENT GENUINE BERYLLIUM BEX™ DIAPHRAGM ASSEMBLIES FOR LOUDSPEAKERS

Our Truextent genuine beryllium BeX4008/4016 precision replacement diaphragms combine premiere materials with precision manufacturing to provide exceptional power handling, high sensitivity and significantly improved clarity of sound with extended bandwidth over that of factory originals. BeX diaphragm assemblies are engineered to fit a variety of large format compression drivers.

All Truextent BeX diaphragms are designed with aluminum wire edgewound voice coils, hot-formed Truextent genuine beryllium domes and PEEK polymer surrounds. They are available in 8Ω and 16Ω impedances and the BeX4000 series fits a variety of JBL and Radian compression drivers.

There is no other material like beryllium for loudspeakers and headphones. Beryllium's unique combination of high stiffness, low mass, and high damping enhances speakers and enables the highest definition audio and crystal-clear sound.
