B&C has expanded their DS Series of high motor strength subwoofers to include 4” coil motor options. The DS Series are the next evolution in professional subwoofers, using 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 new 15DS100 and 18DS100 both feature a 37mm long, 4 inch diameter (100mm) Copper Clad Aluminum Wire voice coil, ventilated voice coil gap, and an aluminum demodulation ring to reduce distortion.
Both are rated for 1500watt AES power, ~97dB sensitivity, and over 14.0mm of Xvar excursion. Both models are available in 8 Ohm or 4 Ohm impedances.

These high energy subwoofers are significant step forward from similar models in the B&C range, and perfect for reflex, and horn loaded cabinets where small cabinet size and low frequency extension are priorities.
