DS18 Carbon18.1D- 18" High Excursion Subwoofer with Carbon Fiber Cone | 3500W RMS / 7000W Peak | Dual 1-Ohm Voice Coil
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.

Real Installs. Real Sound.
See what enthusiasts are saying — straight from their builds
Low End You Can Feel
Bass Built for Daily Driving and Competition
Controlled Low End
Designed for tight, repeatable bass rather than one-note boom, so basslines and kick drums stay separate.
Built to Take Power
Voice coil, spider and cone materials are matched to the rated RMS so the sub handles sustained output.
Match the Enclosure
Performance depends on the box. Sealed for accuracy, ported for output. See the specs for recommended volume and tuning.
Wire It Right
Coil configuration decides your final impedance. Match it to a load your amplifier is stable at before wiring.
