What we know about the measurement:
Seeburg X2 is a passive liveportable that cost around 2200 USD for a pair.
 Quality of the measurement data is medium.
 Origin of the data is Seeburg.
 Format of the data is a GLL file .

Sensitivity:
 Sensitivity: 97.1dB (avg. 100Hz1kHz for 2.83V estimated at 1m).
 Sensitivity: 77.1dB computed at the measurement distance (10.0m) over the same frequency range.
 3dB (resp. 6db) point v.s. reference is at 90.0Hz (resp. 80.0Hz).
 Reference level is normalised to 0.2dB computed over the frequency range [300.0Hz, 5000.0Hz].
 Frequency deviation is 2.9dB over the same frequency range.
 Directivity
 Horizontal directivity is (40.0°, 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
 Tonality (Preference) Score is 3.44
and would be 6.7 with a
perfect subwoofer.
 Details: NBD: ON 0.461, LW 0.466, SP 0.519, PIR 0.462; SM: SP0.839, PIR0.669; LFQ 1.742, LFX 82Hz
 Tonality (Preference) Score is 4.74
with an EQ and would be 7.88 with a
perfect subwoofer and the same EQ.
 Details: NBD: ON 0.375, LW 0.326, SP 0.421, PIR 0.346; SM: SP0.96, PIR0.932; LFQ 1.742, LFX 77Hz
 Tonality (Preference) Score is 3.44
and would be 6.7 with a
perfect subwoofer.
