WS 17 E - 8 Ohm


Art. No. 1055


17 cm (6.5") HiFi woofer with coated paper cone, elastic rubber surround and inverse dust-cap. Due to the balanced frequency response also suitable as low-midrange driver for 4-way speaker systems. Due to the special basket design especially suitable as replacement driver for many HiFi speakers.
