What we know about the measurement:
Optimal Audio Cuboid 3 is a passive bookshelves that cost around 85 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: 74.0dB (avg. 100Hz-1kHz for 2.83V estimated at 1m).
- Sensitivity: 54.0dB computed at the measurement distance (10.0m) over the same frequency range.
- -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.
- Details: NBD: ON 0.809, LW 0.816, SP 0.893, PIR 0.842; SM: SP0.062, PIR0.003; LFQ 0.482, LFX 100Hz
- Tonality (Preference) Score is 3.37
with an EQ and would be 6.68 with a
perfect subwoofer and the same EQ.
- Details: NBD: ON 0.46, LW 0.46, SP 0.552, PIR 0.497; SM: SP0.801, PIR0.705; LFQ 0.37, LFX 85Hz
- Tonality (Preference) Score is -0.46
and would be 3.15 with a
perfect subwoofer.
