What we know about the measurement:

Bose ArenaMatch AM20 is a passive toursound that cost around 5000 USD each.

  • Quality of the measurement data is high.
  • Origin of the data is Bose.
  • Format of the data is a GLL file .
  • Sensitivity:
    • Sensitivity: 100.5dB (avg. 100Hz-1kHz for 2.83V estimated at 1m).
    • Sensitivity: 80.5dB computed at the measurement distance (10.0m) over the same frequency range.
  • -3dB (resp. -6db) point v.s. reference is at 56.0Hz (resp. 53.0Hz).
  • Reference level is normalised to -0.2dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 3.3dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (-30.0°, 20.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
    • Vertical directivity is (-10.0°, 10.0°) 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 1.73 and would be 4.04 with a perfect subwoofer.
      • Details: NBD: ON 0.808, LW 0.832, SP 0.95, PIR 0.879; SM: SP0.602, PIR0.433; LFQ 2.024, LFX 49Hz
    • Tonality (Preference) Score is 4.52 with an EQ and would be 6.84 with a perfect subwoofer and the same EQ.
