Placing your
loudspeakers
This chapter contains general information
about installing and placing your speakers.
These are general hints and tips, so there
may be exceptions.
Even the most competent HiFi equipment
will sound mediocre in the wrong
environment. There are a few basic rules
concerning loudspeaker placement and
installation:
Carpets, curtains and some furniture absorb
midrange and high frequency sounds, which
is preferable. In contrast, big empty areas
reflect these frequencies producing a hard,
unpleasant and blurry sound. Apart from
colouring the sound, the stereo perspective
will deteriorate. Reflections from a room
can roughly be compared to the reflections
causing "ghost" images on a TV screen.
If a loudspeaker is placed near a wall,
ceiling or floor the lower frequencies will be
amplified by the room. Sometimes this is
desirable, sometimes not (it may lead to
indistinct bass reproduction).
The bass amplification becomes more
obvious if the speaker is placed near a
corner. Thus, for a clear sound the speaker
should be placed at least 30 cm (about 12
inches) away from the wall.
However, there are exceptions room this
rule. For some types of walls/rooms it may
be an advantage placing the loudspeaker
closer to the wall.
Be aware that some furniture may vibrate,
causing rattling noises at high sound levels.
Quadratic rooms or rooms where the length
is close to twice the width should be
avoided. These rooms tend to cause
unwanted resonance and room modes.
The angle of the speakers according to the
listener is of great importance.
