DSM 50 FFL - 8 Ohm

Art. No. 1163

50 mm (2") High-End titanium dome driver for the midrange band between 800 and 5000 Hz. Due to the enormously strong and ultra-light titanium dome and in conjunction with a highly damped surround, linear frequency response and no partial oscillations. Due to the enormously high magnetic flux in the ferrofluid-filled air-gap a high efficiency and high power handling are possible.
