What we know about the measurement:
Yamaha NS-800A is a passive bookshelves that cost around 4800 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: 85.5dB (avg. 100Hz-1kHz for 2.83V measured at 1m).
- -3dB (resp. -6db) point v.s. reference is at 64.5Hz (resp. 43.9Hz).
- Reference level is normalised to -0.2dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 2.8dB over the same frequency range.
- Directivity
- Horizontal directivity is (-70.0°, 60.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Vertical directivity is (-10.0°, 40.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Tonality (Preference) Score
- Tonality (Preference) Score is 4.46
and would be 6.23 with a
perfect subwoofer.
