CORE80

High-end 80 mm (3") midrange driver

The magnesium composite midrange drivers convince all along the line, they feature the typical perforation of the membrane and are covered by means of an olefin film. The matt-coated dust dome and the ventilation-optmized pole plate with the multi-ventilated neodymium drive ensure a powerful drive. From the combination of a glass fiber coil carrier for a reduced eddy current effect, the rotationally symmetrical stranding to avoid wobble effects and the flow-optmized core bore with integrated damping foam, a high-end midrange driver in a class of its own is created. The optimal magnetic field symmetry with the extremely stable, flow-optimized and heat dissipation optimized, powder-coated aluminum die-cast basket makes the midrange driver a real highlight - development and manufacture Made in Germany!
