- Quality of the measurement data is high.
- Origin of the data is ErinsAudioCorner.
- Format of the data is generated by a Klippel NFS .
- Sensitivity: 83.8dB (avg. 100Hz-1kHz for 2.83V estimated at 1m)
- -3dB (resp. -6db) point v.s. reference is at 54.2Hz (resp. 45.4Hz).
- Reference level is normalised to -0.0dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 3.0dB over the same frequency range.
- Directivity
- Horizontal directivity is (-70.0°, 60.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Vertical directivity is (-20.0°, 30.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Tonality (Preference) Score
- Tonality (Preference) Score is 4.91
