Ground Zero GZNW 15 NEO-EXTREME Subwoofer

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

The GZNW 15NEO-EXTREME isn’t just a subwoofer—it’s a weapon of sonic destruction. This 15" monster from Ground Zero’s flagship Nuclear Series is engineered for extreme SPL domination and peak performance under pressure. Featuring a multi-piece neodymium motor, 3" aluminum voice coil, and a coated carbon-fiber cone mounted in a solid aluminum cast basket, it’s designed to deliver raw, controlled power at any level.

With an eye-watering Xmax of 65 mm, 3000W RMS power handling (6000W max), and Klippel® optimization throughout, this sub delivers relentless low-end authority without compromise. Dual 1-ohm voice coils and an ultra-efficient motor structure make it ideal for both high-output daily drivers and competition-grade SPL builds.

This is not for the faint-hearted—this is for bassheads and competitors who want to flex, feel, and shake the world. Respect the music... or get out of the way.
