6. Connect the speaker cable to your
AV receiver or multi-channel active
subwoofer. You should be able to
find corresponding notes in the
user manual of your device.
Removing the protective
grid
You can remove the protective grid
by carefully reaching behind it and
slowly pulling it off to the front.
By removing the protective grid,
especially high frequencies will sound
clearer.
When putting the protective grid on,
please make sure that the installa-
tion pins slide directly into the corre-
sponding jacks on the speaker.
Crossover frequency
We recommend a crossover
frequency of 80–100 Hz. Where
possible, set your AV receiver or
DecoderStation as close as possible
to this value.
Operation in full-range mode is also
possible (all speakers set to “Large”).
However, the maximum volume is
slightly lower in this case.
