Usher Debuts The Be-718 Tiny Dancer Stand-Mounted Speaker Featuring Beryllium Tweeters
Experience The Be-718 Speakers at the Home Entertainment Show
Room 1507 in New York’s Grand Hyatt Hotel, May 11th through the 13th
Dallas, TX, May 4th, 2007 • Usher Audio Technology, manufacturers of high value, high performance speaker systems and electronics, debuts the stand-mounted Be-718 Tiny Dancer at this year’s Home Entertainment show.
Usher Audio speakers and electronics are built for the experienced listener who won’t compromise on sound quality even at moderate prices. The spectacular stand-mounted Be-718s–the Tiny Dancers with a Huge Presence–features Ushers’ own 1.5-inch Be beryllium dome tweeters and carbon-impregnated paper-cone midbass drivers.
The Be-718s effortlessly fill even medium-large rooms with musical dynamics; the integration, speed and clarity of its drivers are exceptional. Expansive, quick upper frequencies are redolent with harmonics for female vocals or the quick shimmer of brass. A fast, open and seductive midrange caps deep, taut, powerful bass.
The beautifully engineered Be tweeters on the Be-718s uncover low-level details usually lost in the noise floor of less resolving speakers. The esteemed Dr. Joseph D’Appolito serves as Usher’s technical consultant, providing guidance in crossover design. The result is suave, elegantly powerful, transparent sound from beautifully-crafted and lustrously-finished cabinets at very affordable real-world prices.
The Be-718s, like all Usher speakers, are produced with skill and pride in an ultra-modern factory in Taiwan with great attention to manufacturing efficiency and productivity, turning out beautifully-crafted speaker systems incorporating advanced technologies like the Be beryllium midrange drivers found in the floorstanding Dancer Be-10 and Be-20 along with our superbly-engineered beryllium tweeters.

For The Technically Inquisitive:
Beryllium Domes and Usher’s Drivers
Usher has been producing speakers in Taiwan for more than thirty years, and makes a number of specialized in-house drivers featuring Be beryllium ceramic diaphragms. These are created by heating beryllium formers to greater than 700 degrees, transforming them into brittle but extremely high-strength beryllium oxide. This ceramic’s enormous strength-to-weight ratio pushes the Be dome tweeter’s transient response to an extraordinary level while minimizing distortion as no fabric-dome can claim.
The Be tweeters’ upper-frequency response is extremely focused and dynamic, but full-bodied, grain- and glare-free. Some manufacturers run their beryllium tweeters above 30kHz because they can, but research with the standard-setting Klippel R&D System (http://www.klippel.de/) that dynamically measures non-linear motion clearly shows that running beryllium tweeters out to almost 40kHz causes break-up distortion. Usher’s Be tweeter operates up to 30kHz eliminating the dual resonance points most beryllium tweeters are saddled with.
As a cost-cutting measure some manufacturers specify a voice coil that’s smaller than the dome it drives, but that creates resonance and distortion. Usher uses a full 1.5-inch voice coil driving the diaphragm close to its outer edge for better control, higher velocity, and power without break-up distortion. One cost-cutting technique some use is specifying
Symme-Motion® Technology Explained
Usher’s Symme-Motion® technology–applied to all Usher drivers–symmetrically locates the voice coil within each driver’s magnetic field “linearizing” the motor’s movements. That is to say, when applying positive voltage to the cone moving it outwards, it must move backwards in an exactly symmetrical way when presented with the same negative voltage. Symme-Motion® ensures the voice coil remains exactly centered within the magnetic field.
Usher ensures optimal symmetry and linearity for an amazing lifelike sound as individual drivers and paired speakers are closely toleranced to within 0.2dB sensitivity for stereo pairs before we’ll let you have them! They arrive at your door tuned to begin making music!
Another element of Usher’s driver designs are the selection of materials and the design of the supporting basket or spider. Without careful engineering the baskets may act like springs and cause non-linearities in the output. Even the driver surrounds are designed to absorb vibrations that might otherwise reflect back into the cone resulting in more non-linearities.
