Description
Celestion CF18VJD 18-inch Subwoofer Speaker 1,600 Watt RMS 8-ohm
Product Features
18″ ferrite magnet, cast aluminum chassis LF driver delivering 1600Wrms (AES Standard) power handling and 97dB sensitivity
5″ high temperature, dual layer, Inside/Outside voice coil for higher efficiency, preventing sensitivity loss through thermal compression
FEA optimized magnet assembly delivers highly symmetrical cone – movement, leading to exceptionally low harmonic distortion
Vented front plate increases airflow to provide enhanced cooling
Twin demodulation rings reduce flux modulation, minimizing electromagnetic distortion
Double suspension and “multi-roll” surround provide exceptional linearity at extremes of cone excursion
