The following points contains 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 a 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 (about 12 inch) away from the wall.
Some constructions are designed to be placed close to a wall.
Furniture
Be aware that furniture may vibrate creating bad sound at loud bass levels.
Room dimension
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. It may also work as an antenna picking up various signals that may
become a 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.
