  • Origin of the data is ErinsAudioCorner.
  • Format of the data is generated by a Klippel NFS .
  • -3dB (resp. -6db) point v.s. reference is at 54.2Hz (resp. 51.3Hz).
  • Reference level is normalised to -0.3dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 7.1dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (0.0°, 0.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
    • Vertical directivity is (-50.0°, 40.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
  • Tonality (Preference) Score
    • Note: The tonality (Preference) score does not make sense for omnidirectional speakers. Don't give too much credits to the value.

    • Tonality (Preference) Score is 3.58 with an EQ and would be 6.05 with a perfect subwoofer and the same EQ.
      • Details: NBD: ON 0.917, LW 0.613, SP 0.408, PIR 0.385; SM: SP0.712, PIR0.779; LFQ 0.259, LFX 54Hz
