This chapter contains common information on
loudspeaker placement and installation.
These are general rules, so there are exceptions.
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 absorb mid
range and high frequency sound, and this is
preferrable. Big empty areas, on the other hand,
reflect it and produce hard reflections 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 amplify 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 at least 30 cm (about
12 inch) away from the wall
Some constructions are made to be placed closed to
a wall.
Quadratic rooms or rooms where the length is
exactly twice as long as the width should be
avoided,
since
they
resonance.
Be aware that furniture may vibrate and thus create
bad sound at loud bass.
To get the best result the front speakers should be
placed symmetrical in front of the listener. The
distance between the front speakers should be
around 80% of the distance to the listener. In other
words, the recommended angle between the front
speakers should be 45°
Either you can have the loudspeakers angled in
towards the listener or you can have them directed
straight ahead. Some loudspeakers sound better
when angled, but this may also depend on
reflections from the side walls. By angling the
loudspeakers inwards, you decrease unwanted
reflections and thus you get a better stereo
perspective.
