Overview

B&C 18DS115-4 18" Professional Neodymium Subwoofer 4 Ohm

B&C's 18DS115 18" subwoofer is the next evolution in high output subwoofer design. Using a new, longer, four layer aluminum voice coil to produce more energy in the gap, higher sensitivity, lower distortion, and better overall performance. The 18DS115 features a 40 mm long, 4.5" diameter (116mm) copper clad aluminum wire voice coil. With a 1,700watt AES power rating, 98 dB sensitivity, and over 16.5 mm of linear excursion, this high energy subwoofer is a significant step forward from similar models in the B&C range, even approaching the performance of their 6" voice coil alternatives.
