What we know about the measurement:

ATC SCM20SL MK2 is a passive bookshelves

  • Quality of the measurement data is low.
  • Origin of the data is Misc.
  • Format of the data is a set of 36 horizontal and 36 vertical measurements .
  • Sensitivity: 67.8dB (avg. 100Hz-1kHz for 2.83V measured at 1m).
  • -3dB (resp. -6db) point v.s. reference is at 170.0Hz (resp. 100.0Hz).
  • Reference level is normalised to 0.9dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 2.2dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (-50.0°, 50.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
    • Vertical directivity is (-20.0°, 20.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
  • Tonality (Preference) Score
    • Tonality (Preference) Score is 2.05 and would be 6.03 with a perfect subwoofer.
