Ascend Acoustics Luna Duo measurements provided by Audio Science Review

Ascend Acoustics Luna Duo is a passive center speaker that cost around 800CHF for a each .

  • -3dB (resp. -6db) point v.s. reference is at 85.0Hz (resp. 64.0Hz).
  • Reference level is normalised to -0.0dB computed over the frequency range [300.0Hz, 10000.0Hz].
  • Frequency deviation is 4.3dB over the same frequency range.
  • Horizontal directivity is (-80.0°, 83.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
  • Vertical directivity is (-14.0°, 14.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
  • Preference Score is 1.2 and would be 4.0 with a perfect subwoofer.
