ESB 3.UMA

Main Features

– This special and exclusive component driver is a concept conceived way back in 1970’s. Its aim is to concentrate medium and tweeter emissions in a single virtual point. This minimizes phase delays and irregularities at the crossover point.
– The neodymium magnet is high grade type to eliminate magnetic losses at elevated temperatures and to concentrate more force in less space.
– The tweeter has a silk-impregnated, thin fabric dome diaphragm for a smooth sound, with an outer suspension covered with a high-loss damping material to eliminate edge vibration and resonance.
– Pressed paper cone with waterproof treatment (midrange) for the ideal marriage between lightness, stiffness and the ability of the cone to dampen any unwanted vibration.
– The voice coil uses an aluminum support and a double layer winding technology of copper wire with an aluminum core.
