- Origin of the data is ASR .
- Format of the data is generated by a Klippel NFS .
- Sensitivity: 85.9dB (avg. 100Hz-1kHz for 2.83V measured at 1m)
- -3dB (resp. -6db) point v.s. reference is at 85.0Hz (resp. 64.5Hz).
- Reference level is normalised to -0.2dB computed over the frequency range [300.0Hz, 5000.0Hz].

- Directivity
- Horizontal directivity is (-60.0°, 50.0°) 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 1.5
and would be 4.3 with a
perfect subwoofer.
- Details: NBD: ON 0.91, LW 0.81, SP 0.8, PIR 0.79; SM: SP0.63, PIR0.53; LFQ 0.83, LFX 64Hz
- Tonality (Preference) Score is 3.7
with an EQ and would be 6.3 with a
perfect subwoofer and the same EQ.
