BERYLLIUM DIAPHRAGM COMPRESSION DRIVER

Richard Kontrimas, however, Kontrimas has since retired and the company is under new ownership. Due to beryllium’s unique physical properties of stiffness and damping, the BeX diaphragm assembly series eliminates ringing and distortion. A diaphragm, for example, should move in a perfect pistonic motion like a piston , with all points moving in uniform and only in the desired direction. The beryllium diaphragm has the best top octave decay characteristics of the four materials and shapes. Evaluations will be conducted in three phases, comparing aluminum, beryllium and titanium in each phase.

In turn, the unique properties of aluminum, titanium and beryllium were fed into the model while the actual geometry of the theoretical diaphragm was unaltered. The titanium ribbed diaphragm shows the worst ringing, exhibiting long decay at both the upper two octaves and at 1 kHz.

Coaxial loudspeakers were introduced shortly thereafter, followed by woofers and finally, complete loudspeaker systems. A diaphragm, for example, should move in a perfect pistonic motion like a pistonwith all points moving in uniform and only in the desired direction.

The vibrations of aluminum, titanium, and beryllium compression driver domes were measured using a Klippel SCN laser scanner. Two 28 mm Dome Tweeters from Dayton Audio: 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.

This effect is particularly evident in the top octave response and decay differences between the smooth, fast-decaying beryllium driver and the peaky, long-ringing ribbed titanium driver.

Due to beryllium’s unique physical properties of stiffness and damping, the BeX diaphragm assembly series eliminates ringing and distortion. This means the first breakup will occur at a much higher frequency—well outside the audible range in most cases. 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.

BeX diaphragm assemblies are engineered to fit a variety of large format compression drivers. Truextent is a registered trademark of Materion Brush, Inc. 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.

Our high efficiency BeX diaphragms deliver exceptional power handling, high sensitivity and significantly improved clarity of sound with extended bandwidth over that of factory originals or other aftermarket diaphragms. Most importantly, VUE Audiotechnik is committed to bringing these inherent benefits to a much bery,lium market, while also exploring new applications for this exceptional metal throughout the entire loud- speaker ecosystem.

Because beryllium is extremely light and stiff, it does a better job of maintaining its structural integrity under load and avoiding these breakups.

There is no other material like beryllium for loudspeakers and headphones. We can view both time and frequency response on the same graph using 3-dimensional cumulative spectral decay waterfall plots. Aluminum does not perform as well in higher power applications due to its lower overall strength.

The remainder of this article will explore these exact qualities in greater detail. This compreession important because the frequency at which the first breakup occurs in any metal, is analogous to the speed of sound through that metal. These revolutionary HF transducers will form the foundation for an expanded range of ultra high-performance professional loudspeakers capable of delivering measurable improvements in everything from response linearity to output and long-term durability.

The h-Class and al-Class systems are only the beginning. The first six breakup modes.

The tradeoff is higher Q resonances, which create obvious non-linearities above 10kHz.
