What we know about the measurement:
- 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 38.7Hz (resp. 36.5Hz).
-
Reference level is normalised to -0.1dB
computed over the frequency range [300.0Hz,
5000.0Hz].
-
Frequency deviation is 3.8dB over the same frequency range.
- Directivity
-
Horizontal directivity
is (-40.0°, 40.0°)
between 1kHz and 10kHz. Angle computed for +/-6dB.
-
Vertical directivity
is (-10.0°, 20.0°)
between 1kHz and 10kHz. Angle computed for +/-6dB.
- Tonality (Preference) Score
- Tonality (Preference) Score is 4.84
and would be 6.52 with a
perfect subwoofer.
- Details:
NBD: ON 0.644,
LW 0.52, SP
0.524, PIR
0.478; SM:
SP0.871,
PIR0.806; LFQ
1.426, LFX 35Hz
- Tonality (Preference) Score is 6.02
with an EQ and would be 7.42 with a
perfect subwoofer and the same EQ.
- Details:
NBD: ON 0.503,
LW 0.404, SP
0.491, PIR
0.384; SM:
SP0.943,
PIR0.924; LFQ 1.241, LFX 30Hz
-
Note: measured with broadband noise at 2m. DUT is a DDQ12 with a DDQ Sub 212. It is unclear to me if the measurements are correct.
