Practice o sound / Installing and placing tips
This chapter contains common information on
loudspeaker placement and installation.
In which
room do you
achieve the
best sound?
No matter how good the equipment is, in the wrong
listening en ironment it will ine itably sound bad.
There are some basic rules concerning a proper
loudspeaker installation:
Re lections
Carpets, curtains and soft furniture absorbs mid
range and high frequency sound, and this is
preferable. Big empty area, on the contrary, reflects
it and produces a hard sound that may lead to a
blurry dialogue. Apart from coloring the sound, also
the perspecti e of the sound will deteriorate.
Reflections in the room can roughly be compared to
the reflections that yield ghost pictures on a TV
screen.
Ampli ication
o bass
requencies
A loudspeaker that is placed near a wall, ceiling or
floor will be amplified in the lower frequencies in a
sometimes not desirable way (since it may lead to
an indistinct sound recreation). This amplification
becomes e en more ob ious 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.
Furniture
Be aware that furniture may ibrate and thus create
bad sound at loud bass.
Room
dimension
Quadratic rooms or rooms where the length is
exactly twice as long as the width should be
a oided, since they may create unwanted
resonance.
Placement o
the
loudspeakers
How the loudspeakers are placed towards the
listener is of great importance.
The ront
speakers
For stereo listening the loudspeakers should be
placed symmetrically in front of the listener. The
distance between the loudspeakers should be about
80% of the distance between the listener and one
loudspeaker, or put in another way: the angle
between the loudspeakers, as seen from the listener,
should be about 45 degrees. This means for
example that if the distance between the
loudspeakers is 2 meters, the listener should be
placed 2,5 meters from the loudspeakers.
Angling?
Either you can ha e the loudspeakers angled in
towards the listener or you can ha e them directed
straight ahead. Some loudspeakers sounds better
