Practice of sound / Installin and placin tips
This chapter contains common information on
oudspeaker p acement and insta ation.
In which room do you
achieve the best sound?
No matter how good the equipment is, in the wrong
istening environment it wi inevitab y sound bad.
There are some basic ru es concerning a proper
oudspeaker insta ation.
Reflections Carpets, curtains and soft furniture absorb
midrange and high frequency sound, and this is
preferab e. A arge empty area, on the contrary,
ref ects it and produces a hard sound that may ead
to a b urry dia ogue. Apart from co ouring the
sound, a so the perspective of the sound wi
deteriorate.
Am lification of bass
frequencies
A oudspeaker that is p aced near a wa , cei ing or
f oor wi be amp ified in the ower frequencies in a
sometimes not desirab e way (since it may ead to
an indistinct sound recreation). This amp ification
becomes even more obvious if the oudspeaker is
p aced near a corner. Thus, for a sound as c ear as
possib e, the oudspeaker shou d be p aced about
30 cm (about 12 inches) away from the wa .
However, there are exceptions from this ru e. For
some type of wa s / rooms it may be advantageous
to p ace the oudspeaker c oser to the wa .
Furniture Be aware that furniture may vibrate and thus create
bad ow frequency sound.
Room dimensions Quadratic rooms or rooms where the ength is
exact y twice as ong as the width shou d be
avoided, since they may create unwanted
resonance.
Placing the louds eakers How the oudspeakers are p aced towards the
istener is of great importance
The front s eakers For stereo istening the oudspeakers shou d be
p aced symmetrica y in front of the istener. The
distance between the oudspeakers shou d be about
80% of the distance between the istener and one
oudspeaker, or put in another way: the ang e
between the oudspeakers, as seen from the istener,
shou d be about 45 degrees. This means for examp e
that if the distance between the oudspeakers is 2
meters, the istener shou d be p aced 2.5 meters
from the oudspeakers.
