Positioning
Distance to back and side walls
Every loudspeaker not only disperses sound energy directly into the room, but also to
the side and even backwards. As a result, time-delayed reflections occur and add to
the original music signal. Thus, when loudspeakers are positioned too close to walls,
the sound quality can be restricted.
Acelec loudspeakers were developed to be placed free-standing, and therefore they
reach their optimum performance when positioned as clear of any walls as possible.
To minimize potential influences from the back and side wall boundaries, it is
recommended that the distance from the speakers to each is at least 0.5 meters,
and ideally the distance from each speaker to the back and side wall should not
be equal.
Adapting the bass reflex port
To minimize low frequency reflections, which will be heard as a thickening of the
sound, the loudspeaker models can be adapted to the room’s acoustic character by
using foam plugs in the bass reflex port. This will essentially attenuate the room-
induced boost in the low frequency range by dampening the deep frequencies,
yielding a more clear and tight sound when the loudspeaker is positioned near rear

Fully insert the foam port plugs packed with your loudspeaker into the bass reflex
tube, to attenuate the bass output (if required).
