DTW 72 4 OHM

Art. No. -

14 mm (0.6") polycarbonate dome driver for the highrange above 4000 Hz. Balanced frequency response and excellent omnidirectional sound distribution. Due to the strong magnetic drive and the ultra-light dome in conjunction with the ferrofluid-cooled voice-coil good efficiency and high power handling.

No longer available.
