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 Vendors-Dolby .
- Format of the data is .
- -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
- Tonality (Preference) Score is 2.33
and would be 5.03 with a
perfect subwoofer.
- 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.
