  • This next evolution subwoofer uses a new, longer, four layer aluminum voice coil. The result is more energy in the gap, higher sensitivity, lower distortion and better overall performance.

    3400 W continuous program power capacity
    116 mm (4.5 in) four layer aluminum voice coil
    30 - 1000 Hz response
    99 dB sensitivity
    60 mm peak-to-peak excursion before damage
    Neodymium magnet allows a very high force factor and linear excursion
    Double silicone spider with optimized compliance
    Ventilated voice coil gap for reduced power compression
    Aluminium demodulating ring for very low distortion

    The 21DS115 features a 36 mm long, 4.5 inch diameter (116mm) Copper Clad Aluminum Wire voice coil. With a 1700watt AES power rating, 99 dB sensitivity, and over 17 mm of Xvar, this high energy subwoofer is a significant step forward from similar models in the B&C range, even approaching the performance of our 6" voice coil alternatives.
