Features

  • Versatile 15" bass and mid-range driver providing 96dB sensitivity and 150Wrms (AES standard) power handling
  • 2" high temperature copper voice coil wound on polyimide for increased reliability
  • Ideal for 2-way and 3-way systems
  • Kevlar-loaded cone with sealed surround and damping for reduced distortion
  • Rigid chassis design for maximum energy transfer
  • Vented magnet assembly for enhanced cooling

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.
