What we know about the measurement:

GR Research NX-Bravo is a passive bookshelves that cost around 1525 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: 84.5dB (avg. 100Hz-1kHz for 2.83V measured at 1m).
  • -3dB (resp. -6db) point v.s. reference is at 76.9Hz (resp. 54.2Hz).
  • Reference level is normalised to -0.2dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 2.0dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (-30.0°, 60.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
    • Vertical directivity is (-30.0°, 30.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
  • Tonality (Preference) Score
    • Tonality (Preference) Score is 5.24 and would be 7.57 with a perfect subwoofer.
      • Details: NBD: ON 0.398, LW 0.387, SP 0.377, PIR 0.35; SM: SP0.935, PIR0.832; LFQ 0.483, LFX 50Hz
