Celestion FTR123070C 12" 350w Woofer

This item is brand-new, factory sealed.

12-in ferrite mid/bass driver provides 350 Watts RMS (AES standard) power handling & 96dB sensitivity 3-in 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 & magnet assembly design further minimizes distortion
