This chapter contains common information on
loudspeaker placement and installation.
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:
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 colouring the sound,
also the perspective of the sound will deteriorate.
Reflections in the room can roughly be compared to
the reflections that yield ghost pictures on a TV
screen.
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 even more obvious if the loudspeaker is
placed near a corner. Thus, for a sound as clear as
possible, the loudspeaker should be placed about
30 cm (about 12 inches) away from the wall.
However, there are exceptions from this rule. For
some type of walls / rooms it may be advantageous
to place the loudspeaker closer to the wall.
Be aware that furniture may vibrate and thus create
bad sound at loud bass.
Quadratic rooms or rooms where the length is
exactly twice as long as the width should be
avoided, since they
resonance.
How the loudspeakers are placed towards the
listener is of great importance.
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.
Either you can have the loudspeakers angled in
towards the listener or you can have them directed
straight ahead. Some loudspeakers sounds better
when angled, but this may also depend on
