Features:
 12" ferrite mid/bass driver provides 350Wrms (AES standard) power handling and 96dB sensitivity
 3" high temperature Inside/Outside voice coil efficiently dissipates heat,preventing sensitivity loss due to thermal compression
 Low frequency response, down to 40Hz
 Intelligent heat management in both chassis and magnet assembly design
 further minimizes distortion
 Specially treated weather-resistant cone
