Adaptation to amplifier electronics of other manufacturers
Because of its internal passive linearization of the frequency response, the Score-5 can also be operated on any
other amplifier electronics. To protect the 5“ drivers at higher volumes from too much excursion by low fre -
quencies, it is necessary to set a lower crossover frequency: High-Pass filter: 65 Hz, Characteristic: Butterworth
24 dB/Okt. In addition, the sound image can be minimally improved by a Bell filter: Center frequency 2.36 kHz,
Quality 6.0 and Gain: -2.00 dB.
Type Freq Q Gain
Bell 2.36 kHz 6.0 -2.00
HPF 65 Hz Butterworth 24 dB/Okt
HPF 114 Hz Butterworth 24 dB/Okt
For an optimal sound result when operating with a subwoofer, the lower cut-off frequency must be adapted to
the Score-5 accordingly (e.g. HPF 114 Hz) or, with overlapping frequency ranges, the phase position must be
metrologically adjusted to each other.
If the Score-5 is used for music transmission without bass support, the lower frequencies can be slightly increa-
sed by means of a Low-Shelf filter: Center frequency 155 Hz, Quality 14.1 and Gain: 3.00 dB. When operating
the Score-5 as a stage monitor, the Low-Shelf filter is not recommended, because the low frequencies gain
energy through the ground coupling.
Type Freq Q Gain
Low Shelf 155 Hz 14.1 3.00
Bell 2.36 kHz 6.0 -2.00
HPF 65 Hz Butterworth 24 dB/Okt
Note: Overdriven signals must be avoided throughout the entire transmission chain. They generate consider-
able thermal and mechanical stresses that can destroy loudspeakers. This is especially true when loudspe-
akers are powered by amplifiers that can deliver less than twice the AES power of the loudspeaker. Only
professional power amplifiers with clip limiters should be used for safe operation.
