Features

  • 15" driver provides extended low frequency range
  • 2.5" edgewound voice coil enables 97dB efficiency and 300Wrms (AES standard) power handling
  • Vented magnet assembly for enhanced cooling
  • Kevlar-loaded cone with sealed surround and damping for reduced distortion
  • Suitable for use in 2-way and 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.
