The data shows the actual frequency response and harmonic distortion performance of four different diaphragms on the same motor assembly using a plane wave tube, which was selected to eliminate the effects that a specific horn would introduce. 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. This type of data has only become readily available in the last 15 years, and is increasingly used to qualify sound quality issues that could be heard but were previously impossible to measure. 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. Radian Audio was founded in by its president, Dr.

Density measures mass per unit volume. Truextent is a registered trademark of Materion Brush, Inc. 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.
This type of data has only become readily available in the last 15 years, and is increasingly used to qualify sound quality issues that could be ckmpression but were previously impossible to measure. Compressoin remainder of this article will explore these exact qualities in greater detail. The aluminum diaphragm has reasonably good decay behavior, both in the upper two octaves and at 1 kHz.
The second will measure physical performance of individual domes through vibration testing, and the final phase involves actual acoustic analyses of a fully- assembled compression driver.

The domes were mounted to the same compression driver motor assembly using a custom fixture that ensures repeatable position.
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.

Due to beryllium’s unique physical properties of stiffness diaphrafm damping, the BeX diaphragm assembly series eliminates ringing and distortion. Coaxial loudspeakers were introduced shortly thereafter, followed by woofers and finally, complete loudspeaker systems.
Radian NEOBe on-axis frequency response. The beryllium diaphragm exhibits the best overall performance.
BeX diaphragm assemblies are engineered to fit a variety of large format compression drivers. The Audio Voice Newsletter.
The Use Of Beryllium In Transducers
With more than two decades of success under its belt, Radian Audio is now entering its third decade as a pro sound manufacturer. Richard Kontrimas, however, Kontrimas has since retired and the company is under new ownership.
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. The data shows the actual frequency response and harmonic distortion performance of four different diaphragms on the same motor assembly using a plane wave tube, which was selected to eliminate the effects that a specific horn would introduce.
Aluminum does not perform as well in higher power applications due to its lower overall strength. This means the first breakup will occur at a much higher frequency—well outside the audible range in most cases. By using a PEEK polymer surround, our diaphragm assemblies have an extended low frequency performance.
Acceleration is the rate of change of velocity. 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. Above that mark, beryllium performs significantly better than the other two.

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. A lower overall mass allows for greater acceleration, which increases both efficiency and frequency extension. Ribbing of the titanium dome and diamond pleated surrounds are a popular method for adding stiffness, thus extending the high frequency response.
Materion provides safety information for a variety of their products and materials. It terms of corporate history, Radian Audio Engineering, Inc. A finite element model was constructed using an identical, mm diaphragm geometry with compressioon only variable being the material. These geometric and vibration scans make it easier to see how the predicted results match the measured results in the next section.
