What we know about the measurement:
Phase Tech PC 3.1 is a passive center that cost around 600 USD
- Quality of the measurement data is high.
- Origin of the data is ASR.
- Format of the data is generated by a Klippel NFS .
- Sensitivity: 88.6dB (avg. 100Hz-1kHz for 2.83V measured at 1m).
- -3dB (resp. -6db) point v.s. reference is at 60.1Hz (resp. 45.4Hz).
- Reference level is normalised to 0.3dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 3.9dB over the same frequency range.
- Directivity
- Horizontal directivity is (-30.0°, 10.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Vertical directivity is (-40.0°, 30.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Tonality (Preference) Score
- Tonality (Preference) Score is 2.94
and would be 4.89 with a
perfect subwoofer.
- Details: NBD: ON 0.661, LW 0.636, SP 0.626, PIR 0.606; SM: SP0.562, PIR0.288; LFQ 0.797, LFX 41Hz
- Tonality (Preference) Score is 5.18
with an EQ and would be 6.68 with a
perfect subwoofer and the same EQ.
- Details: NBD: ON 0.591, LW 0.543, SP 0.503, PIR 0.474; SM: SP0.876, PIR0.814; LFQ 0.771, LFX 32Hz
- Tonality (Preference) Score is 2.94
and would be 4.89 with a
perfect subwoofer.
