(e. g. furniture, shelf units) may not be less than 5 cm on any side.
The aluminium plate and cooling fins of the amplifier at the rear of the active subwoofer serve to cool
the built-in amplifier; for this reason, they must also be at least 5 cm away from all objects and must
not be covered (e.g. by a curtain).
The bass reflex opening(s) on the active subwoofer must not be covered (e. g. by curtains, etc.) in
order to guarantee adequate ventilation of the amplifier.
