- Origin of the data is ErinsAudioCorner .
- Format of the data is generated by a Klippel NFS .
- Sensitivity: 85.1dB (avg. 100Hz-1kHz for 2.83V measured at 1m)
- -3dB (resp. -6db) point v.s. reference is at 79.8Hz (resp. 66.7Hz).
- Reference level is normalised to 0.2dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 3.4dB over the same frequency range.
- Directivity
- Horizontal directivity is (-50.0°, 50.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Vertical directivity is (-50.0°, 50.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Tonality (Preference) Score
- Tonality (Preference) Score is 4.3
and would be 7.1 with a
perfect subwoofer.
