DMR 120 4 OHM

Art. No. -

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