Visaton Speaker Driver - DSM 50 FFL - 8 Ohm High End Titanium Dome Midrange
Art. No. 1163
Characteristics and Sound Properties
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.
