Celestion CF18VJD 18" Sub Woofer 1,600 Watts RMS 8-ohm 5" Voice Coil 25Hz-1.5KHz

NOTE: This sub-woofer will require a high quality reinforced box and professional installation.

Product Features

18" ferrite magnet, cast aluminium 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
