What we know about the measurement:
- Quality of the measurement data is
low.
-
Origin of the data is JBL.
-
Format of the data is
a GLL file
.
-
-3dB (resp. -6db) point v.s. reference is at 48.7Hz (resp. 43.7Hz).
-
Reference level is normalised to 0.1dB
computed over the frequency range [300.0Hz,
5000.0Hz].
-
Frequency deviation is 1.8dB over the same frequency range.
- Directivity
-
Horizontal directivity
is (-50.0°, 40.0°)
between 1kHz and 10kHz. Angle computed for +/-6dB.
-
Vertical directivity
is (-20.0°, 30.0°)
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 6.11
and would be 8.28 with a
perfect subwoofer.
- Details:
NBD: ON 0.191,
LW 0.155, SP
0.317, PIR
0.245; SM:
SP0.864,
PIR0.78; LFQ
3.624, LFX 46Hz
- Tonality (Preference) Score is 7.0
with an EQ and would be 8.95 with a
perfect subwoofer and the same EQ.
- Details:
NBD: ON 0.135,
LW 0.108, SP
0.242, PIR
0.15; SM:
SP0.907,
PIR0.887; LFQ 3.624, LFX 41Hz
-
Note: data is highly smoothed. You can remove at least .6 to 1 to score computations.
