What we know about the measurement:
Optimal Audio Cuboid 8 is a passive bookshelves that cost around 490 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: 111.5dB (avg. 100Hz-1kHz for 2.83V estimated at 1m) . Sensitivity computed at the measurement distance (10m) over the same frequency range: 91.5dB.
- -3dB (resp. -6db) point v.s. reference is at 51.5Hz (resp. 45.0Hz).
- Reference level is normalised to -0.2dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 3.5dB over the same frequency range.
- Directivity
- Horizontal directivity is (-30.0°, 30.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Vertical directivity is (-10.0°, 20.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Tonality (Preference) Score
- Tonality (Preference) Score is 2.92
and would be 5.09 with a
perfect subwoofer.
