Details

Built for extreme low-frequency performance, the DS18 CARBON18.1D 18" 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 CARBON18.1D combines exceptional power handling with a high-excursion design to move massive amounts of air and produce deep, powerful bass. Its dual 1-ohm voice coil configuration provides flexible wiring options, allowing installers to configure the subwoofer for different amplifier loads.

The CARBON18.1D combines premium materials with a powerful 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 and responsive bass reproduction. A 3.5" aluminum voice coil with CCAR winding supports high power handling and improved heat dissipation during extended high-power operation, while the massive 425 oz ferrite magnet provides the motor force needed for high-excursion performance. The foam surround and aluminum basket support the moving assembly during demanding use, while 22.5 mm of one-way Xmax allows the 18-inch driver to achieve substantial cone travel and air displacement. With a 10–200 Hz frequency response, the CARBON18.1D is built for serious high-output systems where deep, powerful bass is the priority.
