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 / 10″ 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.
