Dynaudio Focus
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.
The Focus models were developed to be placed free-standing, and therefore they reach
their optimum performance when positioned as clear of any walls as possible.

To reduce possible influences from the back and sidewalls, the distance to these
boundaries should ideally not be less than 0.5 meter.
Adapting the bass reflex port
To minimize low frequency reflections, which will be heard as a thickening of the sound,
the Focus 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 and minimized backwave reflections when the loudspeaker is positioned near rear
walls.

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