Sundown Audio Xv3 18" D2 Subwoofer | 2500W RMS – Deep, Controlled, Ground-Shaking Bass

If you're chasing brutal lows, massive output, and tight, distortion-free bass, the Sundown Audio Xv3 18" D2 Subwoofer is built for you. Rated at a commanding 2500W RMS and 5000W peak, this 18-inch dual 2-ohm sub is engineered for high-powered daily systems and hard-hitting demo builds.

At the core lies a triple-stacked magnet, 3" 4-layer copper voice coil, and a hyper-extended pole piece, giving the Xv3 an insane 4 inches of peak-to-peak excursion. It's optimized for small ported enclosures, but thrives in boxes up to 50% larger—delivering extended low-end performance with clean control.
