Maximum Performance in the Most Extreme Applications Built for the most demanding sonic applications, the Celestion PowerProX18 is an 18-inch 2,400-watt subwoofer purpose-built to bring the low-end rumble. This subwoofer’s cutting-edge design includes dynamic airflow venting, a polysiloxane laminated dual suspension, and an aluminum demodulation ring — matters perhaps best left to Sweetwater’s speaker gurus, but rest assured that they result in the utmost reliability, efficiency, and distortion-free tone. A double-side weatherproof cone coating completes the package by keeping the PowerProX18 protected from moisture while simultaneously cranking up durability.
