  • Quality of the measurement data is medium.
  • Origin of the data is KEF.
  • Format of the data is .
  • Sensitivity:
    • Company: 86 dB
    • Measured: 84.2 dB (avg. 300Hz-3kHz for 2.83V measured at 1m).
  • -3dB (resp. -6db) point v.s. reference is at 80.2Hz (resp. 49.3Hz).
  • Reference level is normalised to 0.4dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 4.4dB over the same frequency range.
  • Tonality (Preference) Score is *** (measurement is truncated at low frequencies).
  • Tonality (Preference) Score with EQ is *** (measurement is truncated at low frequencies).
  • 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..
