DS18 Carbon15.1D- 15" High Excursion Subwoofer with Carbon Fiber Cone | 3500W RMS / 7000W Peak | Dual 1-Ohm Voice Coil

Built for extreme low-frequency performance, the DS18 CARBON15.1D 15" High Excursion Subwoofer is engineered to deliver massive bass output for high-powered car audio and SPL competition systems. Rated at 3,500 watts RMS and 7,000 watts maximum power, the CARBON15.1D combines exceptional power handling with a high-excursion design to produce deep, powerful bass in demanding applications. Its dual 1-ohm voice coil configuration provides flexible wiring options, allowing installers to configure the subwoofer for different amplifier loads.

The CARBON15.1D combines premium materials with a massive motor structure designed to handle extreme power while maintaining reliable performance. Its carbon-fiber cone and carbon-fiber dust cap provide a lightweight and rigid diaphragm designed for controlled movement during high-excursion operation. A 3.5" aluminum voice coil with CCAR winding supports high power handling and heat management, while the massive 425 oz ferrite magnet provides the motor strength needed to drive the subwoofer with authority. The foam surround and aluminum basket support the moving assembly during demanding use, while 22.5 mm of one-way Xmax allows the 15-inch driver to move substantial amounts of air. With a 10–200 Hz frequency response, the CARBON15.1D is designed to deliver deep, powerful bass for serious high-output systems.
