What we know about the measurement:

Canon S-50 is a passive omnidirectional that cost around 300 USD each.

  • Quality of the measurement data is high.
  • Origin of the data is ASR.
  • Format of the data is generated by a Klippel NFS .
  • -3dB (resp. -6db) point v.s. reference is at 64.5Hz (resp. 58.6Hz).
  • Reference level is normalised to -0.5dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 7.4dB over the same frequency range.
  • 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 -0.22 and would be 2.39 with a perfect subwoofer.
      • Details: NBD: ON 1.418, LW 1.3, SP 0.884, PIR 1.023; SM: SP0.679, PIR0.56; LFQ 0.381, LFX 58Hz
    • Tonality (Preference) Score is 2.48 with an EQ and would be 5.0 with a perfect subwoofer and the same EQ.
      • Details: NBD: ON 0.977, LW 0.822, SP 0.606, PIR 0.629; SM: SP0.739, PIR0.703; LFQ 0.381, LFX 55Hz
