What we know about the measurement:
JBL Control 24CT is a passive inwall that cost around 150 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: 80.4dB (avg. 100Hz1kHz for 2.83V estimated at 1m).
 Sensitivity: 60.4dB computed at the measurement distance (10.0m) over the same frequency range.
 3dB (resp. 6db) point v.s. reference is at 22.4Hz (resp. 22.4Hz).
 Reference level is normalised to 0.1dB computed over the frequency range [300.0Hz, 5000.0Hz].
 Frequency deviation is 1.5dB over the same frequency range.
 Directivity
 Horizontal directivity is (60.0°, 60.0°) between 1kHz and 10kHz. Angle computed for +/6dB.
 Vertical directivity is (60.0°, 50.0°) between 1kHz and 10kHz. Angle computed for +/6dB.
 Tonality (Preference) Score
 Note: The tonality (Preference) score does not make sense for inwall speakers. Don't give too much credits to the value.
 Tonality (Preference) Score is 7.07
and would be 8.37 with a
perfect subwoofer.
 Details: NBD: ON 0.131, LW 0.127, SP 0.2, PIR 0.152; SM: SP0.754, PIR0.635; LFQ 4.227, LFX 29Hz
 Tonality (Preference) Score is 8.69
with an EQ and would be 9.51 with a
perfect subwoofer and the same EQ.
 Details: NBD: ON 0.046, LW 0.027, SP 0.123, PIR 0.067; SM: SP0.868, PIR0.923; LFQ 4.227, LFX 22Hz
