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
