The following points contain common information on loudspeaker placement and installation. These are
general rules, so there are exceptions.
How do I achieve the best
sound?
No matter how good the equipment is, in the wrong listening environment it will inevitably sound bad. There
are some basic rules concerning a proper loudspeaker installation:
Reflections Carpets, curtains and soft furniture absorb mid-range and high frequency sounds, and this is normally
preferable. Big empty areas, on the contrary, reflect the sound which might lead to blurry and unprecise
sound. Apart from coloring the sound, also the perspective of the sound will deteriorate. Reflections in the
room can roughly be compared to the reflections that cause ghost pictures on a TV screen.
Amplification of bass
frequencies
A loudspeaker that is placed near a wall, ceiling or floor will amplify lower frequencies in a sometimes
not desirable way (since it may lead to an indistinct sound reproduction). This amplification becomes
even more obvious if the loudspeaker is placed near a corner. Thus, for a sound as clear as possible, the
loudspeaker should be placed at least 30 cm (~ 12 inches) away from the wall. Though some speaker
designs are constructed to be placed close to a wall.
Furniture Be aware that furniture may vibrate creating bad sound at loud bass levels.
Room dimensions Quadratic rooms or rooms where the length is exactly twice as long as the width should be avoided, since
they may create unwanted resonances.
Cables
Try to keep the cables as short as possible. By its electrical parameters, a long cable will have a bigger
influence on the sound than a short one. The cable can also work as an antenna picking up various signals
that may result in constant noise. Make sure that all connections are clean and free from oxidation. All
connections should be mechanically stable, both power, signal and loudspeaker cables. Signal cables
should be separated from other cables.
