What we know about the measurement:

Dolby CS 128 is a passive cinema speaker .

  • Quality of the measurement data is medium .
  • Origin of the data is Dolby.
  • Format of the data is a set of 36 horizontal and 36 vertical measurements .
  • -3dB (resp. -6db) point v.s. reference is at 51.5Hz (resp. 46.2Hz).
  • Reference level is normalised to -0.1dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 2.3dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (-30.0°, 30.0°) 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 4.58 and would be 6.64 with a perfect subwoofer.
      • Details: NBD: ON 0.54, LW 0.479, SP 0.514, PIR 0.487; SM: SP0.836, PIR0.76; LFQ 2.948, LFX 43Hz
    • Tonality (Preference) Score is 5.51 with an EQ and would be 7.35 with a perfect subwoofer and the same EQ.
      • Details: NBD: ON 0.473, LW 0.374, SP 0.45, PIR 0.395; SM: SP0.91, PIR0.876; LFQ 2.948, LFX 38Hz
