Betyllium speed of sound through beryllium is nearly 2. BeX diaphragm assemblies are engineered to fit a variety of large format compression berylllum. A transducer is an extremely complex electromechanical ecosystem where the entire assembly is required to move very quickly, and in perfect synchronicity. We can view both time and frequency response on the same graph using 3-dimensional cumulative spectral decay waterfall plots.

By rolling beryllium into a thin foil and then hot forming our domes and cones, we offer a durable product with diaphragmm thickness. Because beryllium is extremely light and stiff, it does a better job of maintaining its structural integrity under load and avoiding these breakups. Density measures mass per unit volume.
Truextent Beryllium — VUE Audiotechnik
This analysis intentionally ignores outside influences such as acoustical load, phase plug and horn geometry, in order to focus exclusively on the unique fidelity of each metal. The plots confirm that aluminum exhibits good frequency response above 10kHz, while distortion is also good below 12k Hz. These h-Class systems pair this powerful device with equally advanced LF transducers as well as active electronics that include driver-dedicated amplification and system-optimized DSP.
Comparison of both beryllium solid black curve and aluminum dashed blue curve diaphragm on-axis frequency response. Thanks to their unique beryllium transducers, the h-Class, al-Class and e-Class deliver dramatic improvements in both HF extension and response linearity — far beyond compresssion would have been possible with more traditional aluminum or titanium components.
Unlike other metal domes, Truextent acoustic beryllium offers unparalleled sound dampening that starts to drop-off well before other dome materials. The next-generation BeX diaphragm assembly series delivers more sensitivity and better overall frequency response than traditional metal speaker dome materials like titanium and aluminum.
TRUEXTENT® BERYLLIUM BEX™ DIAPHRAGM ASSEMBLIES FOR LOUDSPEAKERS
There are still many opportunities to improve modern day transducer design, and thanks to the efforts of companies like Materion Electrofusion, the potential for once-esoteric technologies like beryllium to improve both performance and reliability is better than ever. Berylilum lower overall mass allows for greater acceleration, which increases both efficiency bfryllium frequency extension. This new 25 mm dome similar that found in some of the best and most expensive esoteric HiFi speakers systems produces output beyond 30k Hz.
The combination of unique acoustic characteristics and increased sensitivity enhance speakers, enabling the highest definition audio and crystal-clear sound.
Coaxial loudspeakers were introduced shortly thereafter, followed by woofers and finally, complete loudspeaker systems. Following the h-Class, VUE engineers developed a smaller, 1-inch exit compression 1. Aluminum does not perform as well in higher power applications due to its lower overall strength.
Radian Audio was founded in by its president, Dr. This article was originally published in Voice Coil, October Most importantly, VUE Audiotechnik is committed to bringing these inherent benefits to a much broader market, while diaphrzgm exploring new applications for this exceptional metal throughout the entire loud- speaker ecosystem.
This is important because the frequency at which the first breakup occurs in any metal, is analogous to the speed of sound through that metal. This means the first breakup will occur at a much higher frequency—well outside the audible range in most cases.

Materion provides safety information for a variety of their products and materials. Ribbing of the titanium dome and diamond pleated surrounds are a popular method for adding stiffness, thus extending the high frequency response.
It has a smooth, extended frequency response while distortion is comparable to the other materials below 10kHz.
