What we know about the measurement:
JBL Control HST V2 is a passive bookshelves that cost around 400 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: 87.3dB (avg. 100Hz1kHz for 2.83V estimated at 1m).
 Sensitivity: 67.3dB 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 1.0dB over the same frequency range.
 Directivity
 Horizontal directivity is (30.0°, 30.0°) between 1kHz and 10kHz. Angle computed for +/6dB.
 Vertical directivity is (80.0°, 40.0°) between 1kHz and 10kHz. Angle computed for +/6dB.
 Tonality (Preference) Score
 Tonality (Preference) Score is 7.36
and would be 8.23 with a
perfect subwoofer.
 Details: NBD: ON 0.085, LW 0.116, SP 0.157, PIR 0.123; SM: SP0.372, PIR0.486; LFQ 4.942, LFX 22Hz
 Tonality (Preference) Score is 8.81
with an EQ and would be 9.62 with a
perfect subwoofer and the same EQ.
 Details: NBD: ON 0.108, LW 0.097, SP 0.082, PIR 0.023; SM: SP0.451, PIR0.984; LFQ 4.942, LFX 22Hz
 Tonality (Preference) Score is 7.36
and would be 8.23 with a
perfect subwoofer.
 Note: Data provided by JBL in GLL format is highly variable, beware. It ranges from excellent to surprising.
