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.
