Features Include
  • 18" ferrite magnet, cast aluminium chassis LF driver provides 1000Wrms power handling (AES Standard) and 96dB sensitivity
  • 4" high temperature, dual layer, Inside/Outside voice coil for higherefficiency, preventing sensitivity loss through thermal compression
  • FEA optimized magnet assembly and suspension deliver highly symmetrical cone movement, leading to exceptionaly 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
