What we know about the measurement:
JBL 3733 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: 119.2dB (avg. 100Hz-1kHz for 2.83V estimated at 1m) . Sensitivity computed at the measurement distance (10m) over the same frequency range: 99.2dB.
- -3dB (resp. -6db) point v.s. reference is at 69.0Hz (resp. 69.0Hz).
- Reference level is normalised to -0.5dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 5.9dB over the same frequency range.
- Directivity
- Horizontal directivity is (-60.0°, 60.0°) 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 3.82
and would be 6.74 with a
perfect subwoofer.
- Details: NBD: ON 0.604, LW 0.573, SP 0.551, PIR 0.516; SM: SP0.938, PIR0.909; LFQ 3.766, LFX 68Hz
- Tonality (Preference) Score is 4.44
with an EQ and would be 7.36 with a
perfect subwoofer and the same EQ.
- Details: NBD: ON 0.449, LW 0.418, SP 0.489, PIR 0.402; SM: SP0.887, PIR0.861; LFQ 3.766, LFX 68Hz
- Tonality (Preference) Score is 3.82
and would be 6.74 with a
perfect subwoofer.
- Note: Data provided by JBL in GLL format is highly variable, beware. It ranges from excellent to surprising.
