What we know about the measurement:
KEF Reference 203 is a passive floorstanders that cost around 9000 USD for a pair.
- Quality of the measurement data is high.
- Origin of the data is ErinsAudioCorner.
- Format of the data is generated by a Klippel NFS .
- Sensitivity: 87.7dB (avg. 100Hz-1kHz for 2.83V measured at 1m).
- -3dB (resp. -6db) point v.s. reference is at 52.7Hz (resp. 43.9Hz).
- Reference level is normalised to 0.1dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 1.9dB 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 5.78
and would be 7.79 with a
perfect subwoofer.
