What we know about the measurement:
JBL CBT 1000 is a passive cbt that cost around 2600 USD each.
- Quality of the measurement data is low.
- Origin of the data is JBL.
- Format of the data is a GLL file .
-
Sensitivity:
- Sensitivity: 98.4dB (avg. 100Hz-1kHz for 2.83V estimated at 1m).
- Sensitivity: 78.4dB computed at the measurement distance (10.0m) over the same frequency range.
- -3dB (resp. -6db) point v.s. reference is at 115.0Hz (resp. 85.0Hz).
- Reference level is normalised to 0.4dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 3.3dB over the same frequency range.
- Directivity
- Horizontal directivity is (-60.0°, 60.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Vertical directivity is (-10.0°, 10.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Tonality (Preference) Score
- Note: The tonality (Preference) score does not make sense for cbt speakers. Don't give too much credits to the value.
- Tonality (Preference) Score is 3.72
and would be 7.19 with a
perfect subwoofer.
- Details: NBD: ON 0.208, LW 0.168, SP 0.218, PIR 0.177; SM: SP0.088, PIR0.24; LFQ 2.238, LFX 92Hz
- Tonality (Preference) Score is 6.86
with an EQ and would be 9.08 with a
perfect subwoofer and the same EQ.
- Details: NBD: ON 0.112, LW 0.105, SP 0.227, PIR 0.148; SM: SP0.892, PIR0.917; LFQ 1.692, LFX 47Hz
- Note: Data provided by JBL in GLL format is highly variable, beware. It ranges from excellent to surprising.
