Seeburg K20 is
a passive
liveportable
that cost around 4300 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: 125.4dB (avg. 100Hz-1kHz for 2.83V estimated at 1m)
. Sensitivity computed at the measurement distance (10m) over the same frequency range: 105.4dB.
-3dB (resp. -6db) point v.s. reference is at 95.0Hz (resp. 87.5Hz).
Reference level is normalised to 0.1dB
computed over the frequency range [300.0Hz,
5000.0Hz].
Frequency deviation is 2.5dB 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 2.2
and would be 5.67 with a
perfect subwoofer.
