What we know about the measurement:
JBL Synthesis SCL7 is a passive inwall that cost around 1100 USD each.
 Quality of the measurement data is high.
 Origin of the data is ASR.
 Format of the data is generated by a Klippel NFS .
 Sensitivity: 87.2dB (avg. 100Hz1kHz for 2.83V measured at 1m).
 3dB (resp. 6db) point v.s. reference is at 67.4Hz (resp. 54.2Hz).
 Reference level is normalised to 0.1dB computed over the frequency range [300.0Hz, 5000.0Hz].
 Frequency deviation is 4.1dB over the same frequency range.
 Directivity
 Horizontal directivity is (80.0°, 40.0°) between 1kHz and 10kHz. Angle computed for +/6dB.
 Vertical directivity is (30.0°, 30.0°) 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 4.13
and would be 6.54 with a
perfect subwoofer.
 Details: NBD: ON 0.581, LW 0.482, SP 0.484, PIR 0.481; SM: SP0.829, PIR0.754; LFQ 0.09, LFX 52Hz
 Tonality (Preference) Score is 5.71
with an EQ and would be 7.72 with a
perfect subwoofer and the same EQ.
 Details: NBD: ON 0.429, LW 0.321, SP 0.316, PIR 0.304; SM: SP0.897, PIR0.87; LFQ 0.073, LFX 42Hz
