Features

  • 12" Bass and mid-range driver provides 300Wrms (AES standard) power handling and 97dB sensitivity
  • 3" high-temperature copper voice coil wound on polyimide for increased reliability
  • FEA optimised neodymium magnet assembly design for lower weight and reduced harmonic distortion
  • "M-Roll" surround provides progressive excursion control yielding a smooth response curve at extremes of frequency range
  • Kevlar-loaded cone with sealed surround and damping contributes to lower distortion
  • Rigid chassis design for maximum energy transfer

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.
  4. Small signal parameters measured after unit subjected to pre-conditioning signal.
