Special Order Item

  • 18" ferrite woofer provides 1000Wrms power handling (AES Standard) and 97dB sensitivity
  • 4" high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss through thermal compression
  • Flexirol TM surround for greater excursion control
  • Double suspension for exceptional linearity at the highest excursions
  • Low frequency response, down to 30Hz • Smart chassis design minimises acoustic distortion
  • Specially treated, weather-resistant cone
