What we know about the measurement:
LD Systems Stinger 12AG3 is an active liveportable that cost around 745 USD each.
 Quality of the measurement data is medium.
 Origin of the data is LD Systems.
 Format of the data is a GLL file .
 3dB (resp. 6db) point v.s. reference is at 45.0Hz (resp. 42.5Hz).
 Reference level is normalised to 0.0dB computed over the frequency range [300.0Hz, 5000.0Hz].
 Frequency deviation is 3.8dB over the same frequency range.
 Directivity
 Horizontal directivity is (30.0°, 30.0°) between 1kHz and 10kHz. Angle computed for +/6dB.
 Vertical directivity is (20.0°, 10.0°) between 1kHz and 10kHz. Angle computed for +/6dB.
 Tonality (Preference) Score
 Tonality (Preference) Score is 3.24
and would be 5.26 with a
perfect subwoofer.
 Details: NBD: ON 0.668, LW 0.68, SP 0.696, PIR 0.648; SM: SP0.708, PIR0.509; LFQ 1.503, LFX 42Hz
 Tonality (Preference) Score is 5.12
with an EQ and would be 7.13 with a
perfect subwoofer and the same EQ.
 Details: NBD: ON 0.509, LW 0.481, SP 0.525, PIR 0.453; SM: SP0.928, PIR0.894; LFQ 1.503, LFX 42Hz
 Tonality (Preference) Score is 3.24
and would be 5.26 with a
perfect subwoofer.
