B&C 18DS100-4 18" Professional Neodymium Subwoofer 4" Voice Coil 3000W 4 Ohm
This next evolution subwoofer uses a new, longer, four layer aluminum voice coil. The result is less heat, more energy in the gap, higher sensitivity, higher power handling, lower distortion and better overall performance. The 18DS100 features a 36mm long, 4 inch diameter (100mm) Copper Clad Aluminum Wire voice coil. With a 1500 watt AES power rating, 98 dB sensitivity, and over 14.0mm of Xvar, this high energy subwoofer is a significant step forward from similar models in the B&C range.
