G 25 FFL - 8 Ohm

Art. No. 1175

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.
