20-cm (8") high-end woofer with black glass fibre membrane, sturdy die-cast aluminium basket and elastic rubber surround. Very flexible application options thanks to 2 x 4-ohm dual voice coil, which creates a high-quality 8-ohm cabinet in series connection. In conjunction with the extended rear pole plate, the vented spider, the vented magnet and the capton voice-coil carrier, the voice coil guarantees long strokes and optimum level control. https://elecena.pl/product/18519939/1330-visaton-woofer-20-cm 2021-05-20 https://elecena.pl/product/18519939/1330-visaton-woofer-20-cm 2021-10-26 https://elecena.pl/product/18519939/1330-visaton-woofer-20-cm 2022-12-02 https://elecena.pl/product/18519939/1330-visaton-woofer-20-cm 2025-01-26
