What we know about the measurement:

Alcons Audio SR9 is a passive liveportable speaker .

  • Quality of the measurement data is high .
  • Origin of the data is Alcons Audio.
  • Format of the data is a GLL file .
  • Sensitivity: 102.5dB (avg. 100Hz-1kHz for 2.83V estimated at 1m) . Sensitivity computed at the measurement distance (10m) over the same frequency range: 82.5dB.
  • -3dB (resp. -6db) point v.s. reference is at 150.0Hz (resp. 109.0Hz).
  • Reference level is normalised to 0.3dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 2.6dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (-40.0°, 30.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
    • Vertical directivity is (-30.0°, 30.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
  • Tonality (Preference) Score
    • Tonality (Preference) Score is 2.15 and would be 5.87 with a perfect subwoofer.
