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.

X To reduce possible influences from the back and sidewalls, the distance to these boundaries should ideally not be less than 0.5 meter.

walls.

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