Ground Zero Audio 38cm / 15″ High Quality SPL Subwoofer

The GZRW 15XSPL is Ground Zero’s flagship 15" SPL subwoofer from the Radioactive Series, built for pure, ground-shaking performance. Designed around a 75 mm (3") copper voice coil, Klippel®-optimized motor, and reinforced paper cone, this beast is made to dominate both street systems and competition builds.

A high-roll surround, 2-layer Polycot spider, and massive dual 170 mm ferrite magnets provide a crushing Xmax of 45 mm and brutal efficiency. With up to 1200W RMS / 1800W SPL power handling, dual 2-ohm coils, and optimized vented enclosure recommendations, the GZRW 15XSPL brings hard-hitting lows and total control, even at extreme output.
