The ESB 3000 speaker system was developed and assembled with a great commitment to the research of materials and engineering solutions of the highest level. Baskets are engineered for torsional rigidity. Cones are pressed paper with ESB’s waterproof polymer — protection without adding the mass of a shiny coating. Woofers use Y-35 ferrite. Tweeters use a silk-impregnated fabric dome, ferrofluid-cooled coils, and N-42 neodymium.
