2.2.
Positioning the Speakers
NOTE:
The following instructions are intended as guidelines to help you position the speakers
in a suitable way.
2.2.1
Acoustic alignment of the speakers
LANSCHE No.5.1 speakers should be placed at least 20 cm from the back wall, with a slight
inward angle of 5° to 8° to make sure they are not positioned parallel to the wall behind
them.
Due to reasons of sound propagation, placing the speakers close to the wall will
adversely affect the sound quality. The walls reflect the sound, which is perceived by the
listener slightly later than the direct sound emission, thus distorting the main sound signal.
The best way to position your new speakers is to set up a so-called “stereo triangle”. This is
accomplished by arranging the speakers such that they create an equilateral triangle, with
the listener in the third position (equal distance between all points).
