AL 200 DV 2x8 OHM

20 cm (8") High-End woofer with double voice-coil, stiff aluminium cone, solid aluminium die-cast basket and elastic rubber surround. Extremely low mechanical and electrical losses due to vented pole plate, vented damper and capton voice coil carrier. Fast pulse response due to light weight aluminium cone. Suitable for subwoofers, which should be connected in stereo mode.

KM 140

Ring-shaped magnets for the compensation of the stray magnetic field (magnetic shielding). The ring has to be glued on the rear pole-plate (e. g. with Pattex), reducing the stray magnetic field to a minimun, allowing speakers positionings of 20 cm apart from TV or computer screens.Suitable for: AL 200 8 OHM; AL 200 DV 2x8 OHM; GF 200 2 X 4 OHM; GF 250 2 X 4 OHM; TIW 360 8 OHM; TIW 360 DS 2 X 4 OHM; TIW 360 X 8 OHM; TIW 400 8 OHM; TIW 400 DS 2 X 4 OHM; W 250 S 4 OHM; W 250 S 8 OHM; W 300 S 4 OHM; W 300 S 8 OHM; WSP 21 S 8 OHM; WSP 26 S 8 OHM
