Features

  • 6.5" neodymium magnet mid-range driver providing 150Wrms (AES standard) power handling and 95dB sensitivity
  • 1.75" high temperature copper clad aluminium voice coil
  • Suitable for line array applications, utilising a space efficient chassis profile
  • FEA optimised flux distribution in the magnet assembly provides low harmonic distortion
  • "M-Roll" surround provides progressive excursion control, generating a smooth frequency response
  • Intelligent heat management in both chassis and magnet assembly design offers reduced thermal distortion

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.
