B & C Speakers 15DS115-8 LF Drivers 15 Inch Super Bass Woofer 8 Ohm Neodymium Inside Slug Magnet 3200 Watts Continous Power Handling 116-mm Four Layer Aluminum Voice Coil
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 15DS115 features a 40mm long, 4.5 inch diameter (116mm) Copper Clad Aluminum Wire voice coil. With a 1600watt AES power rating, 97 dB sensitivity, and over 14 mm of Xvar, this high energy subwoofer is a significant step forward from similar models in the B&C range.
