This chapter contains general information about
loudspeaker placement and installation.
These are general rules, so there are exceptions in
some cases.
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
preferable. Big empty area, on the contrary, reflects
it and produces hard reflections that may lead to
blurry dialogue. Apart from colouring the sound,
also the perspective of the sound will deteriorate.
More furnishings attenuate unwanted resonances
and act as diffusers, which can improve the sound
dramatically.
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.
How you place the speakers in relation to the
audience is important to get a good soundstage.
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 angle the speakers toward the
listener, or let them stand in a straight-forward
position. Some speaker sound better when they are
angled inward, but it can also be caused by
reflections from side walls. If they are angled
reduces glare and reflections from the walls and
thereby enhances the stereo image.
