Speaker, Celestion, CF18VJD, 18 in., 8 ohm 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 and suspension deliver 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
