Celestion FTR18-4080HDX 8 ohm 18" 1000W Pro Audio Woofer T5602

Features Include

• 18" ferrite subwoofer provides 1000Wrms (AES standard) power handling and a frequency response of 30Hz-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
