Celestion CF1840JD 18" 1200 watt Ferrite Subwoofer 8ohm

The Celestion CF1840JD is a versatile ferrite magnet subwoofer suitable for reflex, scoop or horn loaded use.

18" ferrite magnet, cast aluminium chassis LF driver delivering 1200Wrms (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

Used by DB to replace the 18TBX100.
