25 mm (1") High-End titanium dome driver for the highrange above 2000 Hz. Due to the enormously strong and ultra-light titanium dome and in conjunction with a highly damped sypronyle surround, linear frequency response and no partial oscillations. Due to the enormously high magnetic flux in the ferrofluid-filled air-gap high efficiency and high power handling are possible
