What we know about the measurement:

L-Acoustics X4i is a passive liveportable

  • Quality of the measurement data is medium.
  • Origin of the data is L-Acoustics.
  • Format of the data is a GLL file .
  • Sensitivity:
    • Sensitivity: 79.2dB (avg. 100Hz-1kHz for 2.83V estimated at 1m).
    • Sensitivity: 59.2dB computed at the measurement distance (10.0m) over the same frequency range.
  • -3dB (resp. -6db) point v.s. reference is at 190.0Hz (resp. 150.0Hz).
  • Reference level is normalised to 0.1dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 0.8dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (-50.0°, 50.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
    • Vertical directivity is (-50.0°, 50.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
  • Tonality (Preference) Score
    • Tonality (Preference) Score is 0.92 and would be 5.29 with a perfect subwoofer.
