Features

  • 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
  • FlexirolTM 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

8Ω Frequency Response

Product Graph
  1. Tested for two hours using a continuous, band-limited pink noise signal as per AES standard. Power calculated on minimum impedance. Loudspeaker tested in free air.
  2. Measured on axis at 1W, 1m in 2π anechoic environment.
  3. Xmax derived from: (voice coil winding width-gap depth)/2.
