Binom–A is a unique flat diaphragm broadband emitter. This driver is able to cover the entire hearing range with a very large scattering angle. Its diaphragm made of a special composite, which includes an ultra-light balsa wood and an aerospace aluminum-beryllium alloy. This design has a very high stiffness while remaining extremely light. A special system ensures uniform transmission of sound energy over the entire surface of the diaphragm. This ensures the complete absence of the ‘break-up region’ of the latter. High frequencies are thus devoid of sharp directivity. Very high internal loss factor material of the diaphragm provides ultra linear frequency response. Magnetic system based on neodymium magnets. The constant value of magnetic induction in the air gap provides linear movement of the voice coil. The course of the diaphragm dynamics is + -11 mm.
