What we know about the measurement:

Dolby CS 133 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 61.5Hz (resp. 38.7Hz).
  • Reference level is normalised to 0.3dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 3.6dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (-40.0°, 40.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
    • Vertical directivity is (-20.0°, 10.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
  • Tonality (Preference) Score
    • Tonality (Preference) Score is 2.33 and would be 5.03 with a perfect subwoofer.
      • Details: NBD: ON 0.595, LW 0.485, SP 0.401, PIR 0.407; SM: SP0.563, PIR0.023; LFQ 4.446, LFX 61Hz
    • Tonality (Preference) Score is 5.71 with an EQ and would be 7.44 with a perfect subwoofer and the same EQ.
      • Details: NBD: ON 0.466, LW 0.4, SP 0.4, PIR 0.349; SM: SP0.901, PIR0.847; LFQ 4.276, LFX 36Hz
  • Note: data computed from the 2 GLL files, one for the LF speaker and one for the MH speaker. The crossover used is a LR of order 8 and frequency of 365Hz.
