What we know about the measurement:
JBL SLP14 is a passive surround that cost around 280 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: 79.2dB (avg. 100Hz1kHz for 2.83V estimated at 1m).
 Sensitivity: 59.2dB computed at the measurement distance (10.0m) over the same frequency range.
 3dB (resp. 6db) point v.s. reference is at 92.5Hz (resp. 80.0Hz).
 Reference level is normalised to 0.0dB computed over the frequency range [300.0Hz, 5000.0Hz].
 Frequency deviation is 2.4dB over the same frequency range.
 Directivity
 Horizontal directivity is (80.0°, 80.0°) between 1kHz and 10kHz. Angle computed for +/6dB.
 Vertical directivity is (50.0°, 20.0°) between 1kHz and 10kHz. Angle computed for +/6dB.
 Tonality (Preference) Score
 Note: The tonality (Preference) score does not make sense for surround speakers. Don't give too much credits to the value.
 Tonality (Preference) Score is 3.22
and would be 6.47 with a
perfect subwoofer.
 Details: NBD: ON 0.503, LW 0.486, SP 0.588, PIR 0.517; SM: SP0.78, PIR0.685; LFQ 0.931, LFX 82Hz
 Tonality (Preference) Score is 5.37
with an EQ and would be 8.39 with a
perfect subwoofer and the same EQ.
 Details: NBD: ON 0.255, LW 0.239, SP 0.295, PIR 0.24; SM: SP0.909, PIR0.891; LFQ 0.931, LFX 73Hz
 Note: This is a speaker designed to be mounted on a wall..
