What we know about the measurement:

EAW QX300 is a passive toursound that cost around 3500 USD for a pair.

  • Quality of the measurement data is low.
  • Origin of the data is EAW.
  • Format of the data is a GLL file .
  • Sensitivity:
    • Sensitivity: 108.7dB (avg. 100Hz-1kHz for 2.83V estimated at 1m).
    • Sensitivity: 88.7dB computed at the measurement distance (10.0m) over the same frequency range.
  • -3dB (resp. -6db) point v.s. reference is at 82.5Hz (resp. 73.0Hz).
  • Reference level is normalised to -0.3dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 2.4dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (-60.0°, 60.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
    • Vertical directivity is (-40.0°, 30.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
  • Tonality (Preference) Score
    • Note: The tonality (Preference) score does not make sense for toursound speakers. Don't give too much credits to the value.
    • Tonality (Preference) Score is 4.09 and would be 7.11 with a perfect subwoofer.
      • Details: NBD: ON 0.421, LW 0.46, SP 0.645, PIR 0.518; SM: SP0.884, PIR0.876; LFQ 2.986, LFX 73Hz
    • Tonality (Preference) Score is 4.96 with an EQ and would be 7.98 with a perfect subwoofer and the same EQ.
      • Details: NBD: ON 0.28, LW 0.285, SP 0.491, PIR 0.36; SM: SP0.897, PIR0.897; LFQ 2.986, LFX 73Hz
