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 2
  3. Xmax derived from: (voice coil winding width-gap depth)/2.
  4. Small signal parameters measured after unit subjected to pre-conditioning signal.
