What we know about the measurement:
Optimal Audio Cuboid 15 is a passive bookshelves that cost around 1035 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: 121.0dB (avg. 100Hz-1kHz for 2.83V estimated at 1m) . Sensitivity computed at the measurement distance (10m) over the same frequency range: 101.0dB.
- -3dB (resp. -6db) point v.s. reference is at 45.0Hz (resp. 38.7Hz).
- Reference level is normalised to 0.1dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 5.8dB over the same frequency range.
- Directivity
- Horizontal directivity is (-30.0°, 30.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Vertical directivity is (-20.0°, 10.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Tonality (Preference) Score
- Tonality (Preference) Score is 2.12
and would be 3.9 with a
perfect subwoofer.
- Details: NBD: ON 0.843, LW 0.848, SP 0.89, PIR 0.858; SM: SP0.595, PIR0.381; LFQ 1.358, LFX 37Hz
- Tonality (Preference) Score is 5.11
with an EQ and would be 6.57 with a
perfect subwoofer and the same EQ.
