Features:
15" ferrite woofer provides 400Wrms power handling (AES Standard) and 99dB sensitivity
3" high temperature Inside/Outside voice coil efficiently dissipates heat,
preventing sensitivity loss through thermal compression
FlexirolTM surround for greater excursion control
Saturated gap technology for lower harmonic distortion
Low frequency response, down to 40Hz
Smart chassis design minimises acoustic distortion
