Special Order Item

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
