Features

  • 12" Bass and mid-range driver providing 97dB sensitivity and 250Wrms (AES standard) power handling
  • 2.5" high temperature copper voice coil wound on polyimide for increased reliability
  • Optimised ferrite magnet design reduces weight
  • Double roll surround for greater excursion control
  • For use in 2-way or compact 3-way systems

 

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.
