- Quality of the measurement data is low .
- Origin of the data is Princeton.
- Format of the data is .
- Sensitivity: 92.8dB (avg. 100Hz-1kHz for 2.83V measured at 1m)
- Reference level is normalised to 0.4dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 2.5dB over the same frequency range.
- Directivity
- Horizontal directivity is (-10.0°, 10.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Vertical directivity is (-10.0°, 10.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Tonality (Preference) Score
- Tonality (Preference) Score is -2.88
and would be 3.77 with a
perfect subwoofer.
- Details: NBD: ON 0.87, LW 0.765, SP 0.688, PIR 0.658; SM: SP0.128, PIR0.099; LFQ 10.0, LFX 509Hz
- Tonality (Preference) Score is -2.5
with an EQ and would be 4.16 with a
perfect subwoofer and the same EQ.
