B&C 21DS115-8 21" Neodymium Subwoofer 3400 Watts Program 4.5" Coil 8-Ohm Pro Sub

  • Continuous Power Handling
  • Voice Coil Diameter
  • Magnet Material

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. 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 16.5mm 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.
