FTR12-4080HDX
• 12" ferrite subwoofer offers 1000Wrms (AES) continuous power
handling and a frequency response of 47Hz-3kHz
• 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
