    Visaton Speaker Driver - TW 70 - 8 Ohm Cone Tweeter
    Art. No. 9002

    Visaton TW70 - 8 Ohm Cone Tweeter.
    Visaton TW70 - 8 Ohm Cone Tweeter.

     

    Characteristics and Sound Properties
    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.
