Description
Content	95 dB Sensitivity 1 W / 1 m 1.200 W Power Handling 4" Copper Sandwich Voice Coil for low Power Compression Neodymium Magnet System Double treated Cone for Water Protection Triple Aluminum demodulating Rings for ultra low Distortion Optimal for high Output Subwoofers Light Weight Carbon Fiber Diaphragm	15" ferrite subwoofer offers 1000Wrms (AES) continuous power handling and a frequency response of 40Hz-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 minimises distortion Less than 10kg - very low weight for this product class
