Note
• Do not place the center and rear speakers far away from the
listening position than the front speakers.
• Avoid positioning the speakers in corners, as this will boost the
bass tones too much.
• Placing the speaker behind curtains, furniture etc. will reduce
the treble response, thus reducing the stereo effect
considerably. The listener should still be able to see the
speaker.
• Each room has different acoustic characteristics and position-
ing possibilities are often limited. You can find the best position
for your speakers by experimenting. In general, the speakers
should be arranged as symmetrically as possible.
Height Height Height Height Height
• The best height for front and center speaker is at the height of
your ears (while seated).
• The height of the rear speakers is not less than the height of
your ears (while seated).
See the following diagram. It’s advisable to place the rear
