What we know about the measurement:
Optimal Audio Cuboid 5 is a passive bookshelves that cost around 110 USD each.
- Quality of the measurement data is low.
- Origin of the data is Optimal Audio.
- Format of the data is a GLL file .
-
Sensitivity:
- Sensitivity: 81.9dB (avg. 100Hz-1kHz for 2.83V estimated at 1m).
- Sensitivity: 61.9dB computed at the measurement distance (10.0m) over the same frequency range.
- -3dB (resp. -6db) point v.s. reference is at 122.0Hz (resp. 106.0Hz).
- Reference level is normalised to -0.3dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 2.8dB 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
- Tonality (Preference) Score is -0.13
and would be 3.54 with a
perfect subwoofer.
