- Quality of the measurement data is low.
- Origin of the data is JBL.
- Format of the data is a GLL file .
-
Sensitivity:
- Company: 102 dB
- Measured: 101.0 dB (avg. 300Hz-3kHz for 2.83V estimated at 1m).
- Measured: 81.0 dB computed at the measurement distance (10.0m) over the same frequency range.
- -3dB (resp. -6db) point v.s. reference is at 51.5Hz (resp. 45.0Hz).
- Reference level is normalised to 0.2dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 1.4dB over the same frequency range.
- 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 4.72
and would be 6.98 with a
perfect subwoofer.
- Details: NBD: ON 0.158, LW 0.136, SP 0.231, PIR 0.176; SM: SP0.419, PIR0.097; LFQ 3.359, LFX 48Hz
- Tonality (Preference) Score is 7.24
with an EQ and would be 9.25 with a
perfect subwoofer and the same EQ.
- Details: NBD: ON 0.08, LW 0.08, SP 0.217, PIR 0.134; SM: SP0.928, PIR0.938; LFQ 3.142, LFX 42Hz
- Note: Data provided by JBL in GLL format is highly variable, beware. It ranges from excellent to surprising.
JBL CBT 1000+1000E is a passive cbt that cost around 5000 USD each.
