Description

Overview


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


Features:



  • 3400 W continuous program power capacity

  • 4.5 in four layer aluminum voice coil

  • 30 - 1000 Hz response 99 dB sensitivity

  • Double silicone spider with optimized compliance

  • Ventilated voice coil gap for reduced power compression

  • Aluminium demodulating ring for very low distortion
