DTW 8.12 NG 8 OHM

25 mm (1") HiFi fabric dome driver with rectangular shaped front plate for the highrange above 2000 Hz. Coated dome with linear frequency response and strong magnetic drive for high efficiency. High power handling due to ferrofluid-filled air-gap. Suitable for 2- and 3-way combinations. Due to the front plate shaping especially suitable as replacement unit for many Hifi speakers.

No longer available.
