What we know about the measurement:

KEF Reference 2C Meta is a passive center that cost around 5500 USD

  • Quality of the measurement data is medium.
  • Origin of the data is KEF.
  • Format of the data is .
  • Sensitivity: 87.2dB (avg. 100Hz-1kHz for 2.83V measured at 1m).
  • -3dB (resp. -6db) point v.s. reference is at 64.9Hz (resp. 54.2Hz).
  • Reference level is normalised to 0.6dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 1.6dB over the same frequency range.
  • Tonality (Preference) Score
    • Tonality (Preference) Score is 5.55 and would be 7.94 with a perfect subwoofer.
      • Details: NBD: ON 0.389, LW 0.252, SP 0.345, PIR 0.288; SM: SP0.957, PIR0.899; LFQ 1.152, LFX 51Hz
    • Tonality (Preference) Score is 6.48 with an EQ and would be 8.51 with a perfect subwoofer and the same EQ.
      • Details: NBD: ON 0.292, LW 0.203, SP 0.286, PIR 0.219; SM: SP0.975, PIR0.952; LFQ 0.922, LFX 42Hz
  • Note: the off-axis average curves are truncated at 200Hz as this is close to the LF cut-off limit of our anechoic chamber. The on-axis LF response has been compensated using ground plane measurements carried out in free-field and is therefore valid only for that singular curve..
