What we know about the measurement:
JBL C211 is a passive cinema
- Quality of the measurement data is low.
- Origin of the data is JBL.
- Format of the data is a GLL file .
-
Sensitivity:
- Sensitivity: 96.6dB (avg. 100Hz-1kHz for 2.83V estimated at 1m).
- Sensitivity: 76.6dB computed at the measurement distance (10.0m) over the same frequency range.
- -3dB (resp. -6db) point v.s. reference is at 90.0Hz (resp. 61.5Hz).
- Reference level is normalised to 0.2dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 4.7dB over the same frequency range.
- Directivity
- Horizontal directivity is (-40.0°, 40.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Vertical directivity is (-30.0°, 20.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Tonality (Preference) Score
- Tonality (Preference) Score is 1.14
and would be 4.06 with a
perfect subwoofer.
- Details: NBD: ON 0.834, LW 0.849, SP 0.829, PIR 0.829; SM: SP0.688, PIR0.404; LFQ 3.753, LFX 68Hz
- Tonality (Preference) Score is 4.37
with an EQ and would be 6.53 with a
perfect subwoofer and the same EQ.
- Details: NBD: ON 0.54, LW 0.535, SP 0.602, PIR 0.558; SM: SP0.876, PIR0.807; LFQ 2.789, LFX 46Hz
- Tonality (Preference) Score is 1.14
and would be 4.06 with a
perfect subwoofer.
- Note: Data provided by JBL in GLL format is highly variable, beware. It ranges from excellent to surprising.
