Ground Zero GZNW 38C

The GZNW 38C is a new 15″ subwoofer from the Nuclear series that will leave no one cold!

This subwoofer has been completely redesigned:

A redesigned, airflow optimized aluminum cast basket. Thanks to the airflow optimized basket, this subwoofer breathes better than previous models = more SPL!

Extremely durable and lightweight carbon-fiber cone = can withstand even higher pressures and movements without problems.

A stiffer 7-layer 12″ spider (4-layers in previous models).

New 75 mm / 3″, 8-layer flat wire CCA voice coil ( 4-layers in previous models ) = ths generation GZNW subwoofers continuous power has increased from 3500 W in the previous model to 6000 W!

These subwoofers are designed using Klippel optimization. The testing periods last 10 hours, during which the element′s power endurance is exceeded fourfold, and its behavior is studied thru numerous different measurements. This allows weak points to be eliminated already at the planning stage, resulting in an subwoofer without weaknesses!
