Ribbing of the titanium dome and diamond pleated surrounds are a popular method for adding stiffness, thus extending the high frequency response.
Even more critical, however, is the efficiency at which sound travels through beryllium. The beryllium diaphragm exhibits the best overall performance. It suffers from the top octave and 1 kHz ring.
Truextent® Beryllium BeX Compression Driver Diaphragm Assemblies for Loudspeakers
Read our BeX compression driver diaphragm assemblies data sheet. The beryllium diaphragm has the best top octave decay characteristics of the four materials and shapes.
With more than two decades of success under its belt, Radian Audio is now entering its third decade as a pro sound manufacturer. The titanium diaphragm with no ribs is the second worst performer on the wavelet decay test. This means the first breakup will occur at a much higher frequency—well outside the audible range in most cases. We can view both time and frequency response on the same graph using 3-dimensional cumulative spectral decay waterfall plots. Compresslon has a smooth, extended frequency response while distortion is comparable to the other materials diaphramg 10kHz.
Several major loudspeaker manufacturers quickly identified Radian Diaphraym as an important source for their compression driver needs and became OEM customers. Following the h-Class, VUE engineers developed a smaller, 1-inch exit compression 1.
Unlike diaphrgm metal domes, Truextent acoustic beryllium offers unparalleled sound dampening that starts to drop-off well before other dome materials. These geometric and vibration scans make it easier to see how the predicted results match the measured results in the next section.
Review our technical analysis showing the advantages of BeX in a Radian compression driver. 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.
Because beryllium is extremely light and stiff, it does a better job of maintaining its structural integrity under load and avoiding these breakups. BeX diaphragm assemblies are engineered to fit a variety of large format compression drivers.
This restricts the measurements to only the metallic part of each dome. Let VUE and Materion keep you up to date on how beryllium is improving loudspeaker performance by signing up for our email alerts. Our site uses bfryllium.
The 745NEOBe Compression Driver from Radian Audio
Richard Kontrimas, however, Kontrimas has since retired and the company is under new ownership, based in Orange, CA. This article was originally published in Voice Coil, October Due to beryllium's unique physical properties of stiffness and damping, the BeX diaphragm assembly series eliminates ringing and distortion.
The plots confirm beryllim aluminum exhibits good frequency response above 10kHz, while distortion is also good below 12k Hz.
Richard Kontrimas, however, Kontrimas has since retired and the company is under new ownership. This new 25 comprdssion dome similar that found in some of the best and most expensive esoteric HiFi speakers systems produces output beyond 30k Hz.
As the frequency goes up, bending waves become more visible.
Compression Drivers
A transducer is an extremely complex electromechanical ecosystem berjllium the entire assembly is required to move very quickly, and in perfect synchronicity.
Radian NEOBe on-axis frequency response. Density measures mass per unit volume. To minimize the effects of different suspension methods, these scans were limited to a 51mm radius, 1mm outside the nominal voice coil radius.
Truextent Beryllium
They are also built with aluminum edgewound voice coils with beryllium-copper lead outs. The combination of unique acoustic characteristics and increased sensitivity enhance speakers, enabling the highest definition audio and crystal-clear sound.
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.
