The GZPW 18C is an 18″ subwoofer from the Plutonium series that leaves no one cold!

This subwoofer has been completely redesigned:

A redesigned, more open basket.
Thanks to the open basket, the driver breathes better than previous models = more pressure!

Extremely durable and lightweight carbon fiber cone = withstands even higher pressures and excursions.

10″ Stiffer 7-layer lower suspension (previous models had 4-layer) = the driver keeps up even with more aggressive use.


Ground Zero's Plutonium subwoofers are designed to withstand truly aggressive excursions, produce massive sound pressures, and earth-shattering lows.

The large and very powerful magnet keeps the four-inch voice coil excellently controlled. The sturdy open cast basket is designed to breathe properly and not impede the bass's performance in the enclosure. Thanks to the long voice coil and deep magnet, the driver has an excursion of 80 millimeters! This excursion creates amazing bass reproduction at all frequencies.

These drivers are designed using Klippel optimization. Test cycles last 10 hours, during which the driver's power handling capacity is exceeded fourfold, and its behavior is studied with numerous different measurements. This eliminates weak points already in the design phase, resulting in a driver without weaknesses!
