The Sundown Audio XV4 15-inch Subwoofer is designed for die-hard bassheads who crave deep, hard-hitting low frequencies with accuracy and control. Powered by Sundown’s advanced X v.4 coil design, this subwoofer handles an impressive 3000W RMS and 6000W peak power while maintaining crystal-clear performance under extreme pressure.
With a massive 72.58 square inch cone area and a durable 9.25-inch motor structure, the XV4 15-inch moves serious air, producing deeper lows and more powerful output than smaller drivers. Its 30mm Xmax ensures long, clean linear excursion, giving you chest-crushing bass with minimal distortion.
Engineered for ported enclosures, the XV4 performs best in a 4.25 cubic foot box tuned to 32 Hz — delivering the perfect blend of low-end extension, output, and sound quality. It’s also flexible enough to shine in advanced 4th order bandpass designs for builders who want even more SPL performance.
From daily drivers to full competition builds, the XV4 15-inch stands as one of the most capable and durable subwoofers in Sundown’s lineup.
