What we know about the measurement:

Apple Homepod is an active omnidirectional that cost around 500 USD each.

  • Quality of the measurement data is medium.
  • 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 26.4Hz (resp. 23.4Hz).
  • Reference level is normalised to -0.6dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 5.7dB 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 4.7 and would be 5.6 with a perfect subwoofer.
      • Details: NBD: ON 0.892, LW 0.73, SP 0.542, PIR 0.544; SM: SP0.691, PIR0.762; LFQ 0.298, LFX 23Hz
    • Tonality (Preference) Score is 6.03 with an EQ and would be 6.68 with a perfect subwoofer and the same EQ.
      • Details: NBD: ON 0.7, LW 0.538, SP 0.379, PIR 0.362; SM: SP0.71, PIR0.787; LFQ 0.298, LFX 20Hz

  • Note: ...So what you see below is accurate to about 8 kHz. Above that, there is some error but on-axis response shows surprisingly good agreement so I think we are fine....
