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.
