Visaton Speaker Driver - G 25 FFL - 8 Ohm Fabric Dome Tweeter
Art. No. 1175
Characteristics and Sound Properties
25 mm (1")
fabric dome driver for the high-frequency range above 2000 Hz. Due to the optimised dome shape with double coating in conjunction
with the highly damped surround, linear frequency response has been made possible. Due to the powerful magnetic driver and
the ferrofluid-cooled voice-coil high efficiency and high power handling can be guaranteed.
