Test Notes

  1. Program power is defined as 3 dB greater than AES power.
  2. Tested in free air for two hours using a continuous band-limited pink noise signal as per AES 2-1984 Rev. 2003.
  3. Measured on axis at 2 V, 1 m; SPL is the average at 200, 500, 800 and 1000 Hz.
  4. High-pass filter with slope 12 dB/oct. or higher.
  5. Xmax = (Hvc − Hg) / 2, where Hvc is voice-coil height and Hg the gap height.
  6. Thiele-Small parameters measured after preconditioning (20–22 °C, 50% RH, 2 h) by Klippel LSI. All specifications subject to change without notice.
