Usher BE-10 DMD Floorstanding Speakers, good working condition, 3 month warranty
Here we have a pair of high-end floorstanding loudspeakers from Usher. The BE-10 Diamond DMD were very well regarded and our examples are in full working order. Cosmetically generally good with general sun fading and a few small blemishes - please see photographs.
Usher Diamond DMD Technology: Uncovering Key To Superlative Diamond Sound Because of its extreme hardness and excellent thermal conductivity, diamond has always been considered a potentially great material for loudspeaker diaphragm. Tweeter units with a diaphragm made of synthetic diamond, from the traditional CVD (Chemical Vapor Deposition) method, have been around for quite some time, but many find their sonic performance compromised, due mainly to the relatively high mass of the diamond dome and also to the unfavourable resonance signature of the material itself. At Usher, we saw the promise of diamond as an ideal diaphragm material, but we also reckoned that it would take some original thinking and an innovative approach to the engineering, in order to bring out the best of this unusual material for application in audio. In typical Usher fashion, we took our time to carefully research and develop our own original solutions for both pure diamond and laminate diamond diaphragms, tackling the issues with both imagination and extensive measuring/listening tests. Today, years after we began our quest for the ultimate diamond sound, we're pleased to present to the music-loving public and audiophiles the exciting result of our first diamond technology research project, and we believe the key to superlative diamond sound: The new Usher Diamond DMD series speakers.
Employing the Usher Diamond DMD Technology, our Diamond DMD speakers have a new tweeter unit with an USHER Diamond DMD dome. The DMD dome is effectively a diamond dome with a reduced mass and a well-controlled, appealing sound signature, resembling very closely a perfect piston in its behaviour.This is made possible by its laminated diamond-metal-diamond structure, which consists of a proprietary metal alloy base layer coated with an amorphous diamond-like carbon layer (pure diamond is carbon atoms arranged solely in sp3 bonds; amorphous diamond-like carbon has mixed sp3 and sp2 bonds to achieve its desirable properties) on both sides. The base metal layer of the Diamond DMD dome tames all the diamond layers' unfavourable sonic traits and brings out the best of both materials. The true revolution, however, is in the Diamond DMD tweeter's unprecedented micro-dynamics resolving power. The DMD dome's structural integrity makes possible a surprisingly intact and undistorted reproduction of the input signal, which clearly shows in the reproduced sound as a sense of purity and completeness that is at the same time new and familiar: New in reproduced music but familiar in live performances.
Often considered to have the best midrange in the world, the critically acclaimed BE-10 is now equipped with the incredible USHER Diamond DMD tweeter. Whilst capable of retrieving the last bit of music information in the recording and reproducing a stunning sound stage and palpable imaging, the captures the thrills of the performance and presents the music with such purity and sweetness like no other could.
