Unit conditioned prior to measurement.
• 15" ferrite subwoofer offers 1000Wrms (AES) continuous power
handling and a frequency response of 40Hz-2500Hz
• 4" high temperature Inside/Outside voice coil efficiently
dissipates heat, preventing sensitivity loss through
thermal compression
• Double suspension and a “multi-roll” surround provide
exceptional linearity at extremes of cone excursion
• Intelligent heat management in both chassis and magnet
assembly design further minimizes distortion
• Less than 10kg – very low weight for this product class
