Features

  • 10" neodymium mid/bass unit offers 250Wrms (AES standard) power handling and 96dB sensitivity
  • 2.5" high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss through thermal compression
  • "M-Roll" surround provides progressive excursion control, yielding a smooth response even at extremes of frequency range
  • Extremely lightweight design combined with a highly efficient magnet assembly results in exceptional power-to-weight ratio
  • Intelligent heat management in both chassis and magnet assembly design further minimises 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.
