Description:
20 cm (8″) High-End woofer with black glass fibre cone, solid aluminium die-cast basket and elastic rubber surround. Designed for multi-purpose applications due to 2 x 4 ohms double voice-coil, with excellent properties as 8 ohms drivers in series configuration.
The long stroke voice-coil in conjunction with the extended rear pole plate, the vented damper, the vented magnet and the capton voice-coil carrier guarantees long strokes and highest power handling. Possible connections: (1) one voice coil not connected (2) both voice coils in series (3) both voice coils in parallel.
*(fu: Lower cut-off frequency depending on cabinet).
