Visaton Speaker Driver - W 130 S - 4 Ohm HiFi Low-Midrange Driver
Art. No. 9022
Characteristics and Sound Properties
13 cm (5") HiFi low-midrange driver with coated paper cone, elastic rubber surround and 25 mm voice-coil. Suitable
as woofer and due to the very balanced frequency response also as low-midrange driver especially in large 3-way speaker
systems.
