The GZPW 15C is a new 15″ subwoofer from the Plutonium 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 stiff 7-layer / 12″ spider.

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!
