50 mm (2") High-End fabric dome driver for the midrange band between 800 and 7000 Hz. Due to the optimised dome shape with damping coating in conjunction with the highly damped surround, linear frequency response and no partial oscillations. Due to the powerful magnetic drive and the ferrofluid-cooled voice-coil high efficiency and high power handling can be guaranteed.
