We have multiple measurements for this speaker. Click here to see the default one (which is higher quality if we have one measurement better than the others).
What we know about the measurement:
JBL CBT 70J-1 is
a passive
cbt
that cost around 1000 USD
each.
Quality of the measurement data is
low.
Origin of the data is JBL.
Format of the data is
a GLL file
.
-3dB (resp. -6db) point v.s. reference is at 22.4Hz (resp. 115.0Hz).
Reference level is normalised to 0.3dB
computed over the frequency range [300.0Hz,
5000.0Hz].
Frequency deviation is 5.2dB over the same frequency range.
Directivity
Horizontal directivity
is (-80.0°, 80.0°)
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
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 0.76
and would be 4.59 with a
perfect subwoofer.

Tonality (Preference) Score is 2.05
with an EQ and would be 5.36 with a
perfect subwoofer and the same EQ.
