What we know about the measurement:
Turbosound TBV123 is a passive toursound that cost around 2600 USD each.
 Quality of the measurement data is low.
 Origin of the data is Turbosound.
 Format of the data is a GLL file .

Sensitivity:
 Sensitivity: 110.7dB (avg. 100Hz1kHz for 2.83V estimated at 1m).
 Sensitivity: 90.7dB computed at the measurement distance (10.0m) over the same frequency range.
 3dB (resp. 6db) point v.s. reference is at 46.2Hz (resp. 40.0Hz).
 Reference level is normalised to 5.6dB computed over the frequency range [300.0Hz, 5000.0Hz].
 Frequency deviation is 5.8dB over the same frequency range.
 Directivity
 Horizontal directivity is (20.0°, 20.0°) between 1kHz and 10kHz. Angle computed for +/6dB.
 Vertical directivity is (10.0°, 10.0°) between 1kHz and 10kHz. Angle computed for +/6dB.
 Tonality (Preference) Score
 Note: The tonality (Preference) score does not make sense for toursound speakers. Don't give too much credits to the value.
 Tonality (Preference) Score is 4.35
and would be 6.13 with a
perfect subwoofer.
 Details: NBD: ON 0.637, LW 0.669, SP 0.732, PIR 0.693; SM: SP0.916, PIR0.909; LFQ 2.109, LFX 37Hz
 Tonality (Preference) Score is 5.36
with an EQ and would be 7.2 with a
perfect subwoofer and the same EQ.
 Details: NBD: ON 0.477, LW 0.508, SP 0.53, PIR 0.501; SM: SP0.975, PIR0.952; LFQ 2.109, LFX 38Hz
 Note: TODO: add exact config.
