CELESTION CF1840JD 18 Loudspeaker Driver

Description

• 4" high temperature, inside/outside voice coil for higher efficiency, reducing thermal compression
• Multi-roll surround and double spider provides near perfect linearity to the limits of excursion
• FEA optimized magnet assembly and suspension deliver symmetrical cone movement,and low distortion
• Vented magnet assembly increases airflow to provide enhanced cooling
• Twin demodulation rings reduce flux modulation, minimizing electromagnetic distortion

This cast aluminium, ferrite magnet woofer features a 4" (100mm) diameter voice coil. It delivers 1000Wrms (AES Standard) power handling and 98dB sensitivity and is optimised for use in bass reflex cabinets. 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
