What we know about the measurement:

SONBS SD-10E is a passive toursound that cost around 100 USD each.

  • Quality of the measurement data is high.
  • Origin of the data is SONBS.
  • Format of the data is a GLL file .
  • Sensitivity: 118.0dB (avg. 100Hz-1kHz for 2.83V estimated at 1m) . Sensitivity computed at the measurement distance (10m) over the same frequency range: 98.0dB.
  • -3dB (resp. -6db) point v.s. reference is at 106.0Hz (resp. 82.5Hz).
  • Reference level is normalised to -0.1dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 3.0dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (-40.0°, 40.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
    • Vertical directivity is (-20.0°, 20.0°) 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 2.28 and would be 5.65 with a perfect subwoofer.
      • Details: NBD: ON 0.561, LW 0.554, SP 0.635, PIR 0.564; SM: SP0.805, PIR0.455; LFQ 2.418, LFX 87Hz
    • Tonality (Preference) Score is 4.24 with an EQ and would be 7.1 with a perfect subwoofer and the same EQ.
      • Details: NBD: ON 0.48, LW 0.415, SP 0.551, PIR 0.458; SM: SP0.931, PIR0.856; LFQ 2.183, LFX 67Hz
