TW 70 - 8 Ohm


Art. No. 9002


Cone tweeter with special basket for the high-frequency range above 5000 Hz. Balanced frequency response with brilliant highs and high power handling. Due to the sealed rear no separate high-frequency range housing construction necessary. Especially suitable as replacement unit for many HiFi speakers.
