Features

  • 12" Bass and mid-range driver offering a superior price/performance ratio
  • Provides 97dB sensitivity and 100Wrms (AES standard) power handling
  • 1.75" High temperature copper voice coil wound on polyimide for increased reliability
  • Kevlar-loaded cone with sealed surround and damping for reduced distortion
  • Suitable for use in 2-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.
