Celestion CF1840VD

18" 1000W Speaker 8OHM 

18" ferrite magnet, cast aluminium chassis LF driver delivering 1000Wrms (AES Standard) power handling and 98dB sensitivity

4" high temperature, dual layer, Inside/Outside voice coil for higher efficiency, preventing sensitivity loss through thermal compression

FEA optimized magnet assembly and suspension deliver highly symmetrical cone movement, leading to exceptionally low harmonic distortion

Vented magnet assembly 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
