What we know about the measurement:

Optimal Audio Cuboid 3 is a passive bookshelves speaker that cost around 85USD each .

  • Quality of the measurement data is low .
  • Origin of the data is Optimal Audio.
  • Format of the data is a GLL file .
  • Sensitivity: 84.0dB (avg. 100Hz-1kHz for 2.83V estimated at 1m) . Sensitivity computed at the measurement distance (10m) over the same frequency range: 64.0dB.
  • -3dB (resp. -6db) point v.s. reference is at 115.0Hz (resp. 97.5Hz).
  • Reference level is normalised to 0.2dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 6.8dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (-10.0°, 10.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
    • Vertical directivity is (-30.0°, 10.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
  • Tonality (Preference) Score
    • Tonality (Preference) Score is -0.46 and would be 3.15 with a perfect subwoofer.
