Usher Be-718 Diamond DMD

Diamond technology
Because of its extreme hardness and excellent thermal conductivity, diamond has always been considered a potentially great material for a loudspeaker diaphragm. Tweeter units with a diaphragm made of synthesized diamond from the CVD (chemical Vapor Deposition) method have been around for quite some time, but many find their sonic performance compromized, due mainly to the high mass of the diamond dome and also to the unfaborable resonance signature of the material itself.

The Usher Diamond DMD Technology incorporated the light and stiff Be tweeter diaphragm material with the diamond coating.. This consists of a proprietary metal alloy base layer coated with an amorphous diimond-like carbon layer on both sides. The base metal layer of the Diamond DMD dome tames all of the Diamond layer's unfavorable sonic traits and brings out the best of both materials.

Sonics of the Diamond DMD
The true revolution however is in the Diamond DMD tweeter's unprecidented microdynamic 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.

	Professional Reviews:
	"...I find these Ushers exceptionally endearing and involving, which is by far their most important characteristic. If I were in the market for a stand mount these would be my first choice because, in this price class, I think a speaker that hits all its marks is difficult enough to find but one that is as engaging to listen to as the Usher Be-718 comes along only once in a blue moon..." - John Potis, SixMoons.com
