System Configuration
Speaker Selection / Placement
When all audio, video and system connections have been made, there are a few configuration adjustments to be made. A few minutes spent to correctly
configure and calibrate the unit will greatly add to your listening experience.
Speaker Selection
No matter which type or brand of speakers is used,
the same model or brand of speaker should be used
for the front left, center and right speakers. This
creates a seamless front soundstage, and eliminates
the possibility of distracting sonic disturbances that
occur when a sound moves across mismatched front
channel speakers.
Speaker Placement
The placement of speakers in a multichannel-home-
theater system can have a noticeable impact on the
quality of sound reproduced.
Depending on the type of center channel speaker in
use and your viewing device, place the center
speaker directly above or below your TV or in the
center behind a perforated front projection screen.
Once the center channel speaker is installed, position
the left and right front speakers so that they are as
far away from one another as the center channel
speaker is from the preferred listening position.
Ideally, the front channel speakers should be placed
so that their tweeters are no more than 60 cm off
center from the tweeter in the center channel
speaker. They should also be at least 50 cm from the
TV set to avoid interference when the front left/right
speakers are not magnetically shielded, as it’s with all
common stereo speaker sets but also with the most
complete surround sets (often only the Center
speaker is shielded).
Depending on the specifics of your room acoustics
and the type of speakers in use, you may find that
imaging is improved by moving the front left and right
speakers slightly forward of the center channel
speaker. If possible, adjust all front loudspeakers so
that they are aimed at ear height when you are
seated in the listening position.
Using these guidelines, you’ll find that it takes some
experimentation to find the correct location for the
front speakers in your particular installation. Don’t be
afraid to move things around until the system sounds
correct. Optimize your speakers so that pans across
the front of the room sound smooth.
Surround speakers should be placed on the side walls
of the room, at or slightly behind the listening position.
The center of the speaker should face to you.
If side wall mounting is not practical, the speakers
may be placed on a rear wall, behind the listening
position. The speakers should be no more than 2
meters behind the rear of the seating area.
Subwoofers produce largely non-directional sound, so
regarding only their directivity they may be placed
almost anywhere in a room. But their efficiency is
highly influenced by room size and shape, and the
type of subwoofer used. One method of finding the
optimal location for a subwoofer is to begin by
placing it in the front of the room, about 15 cm from
a wall, or near the front corner of the room. Another
method is to temporarily place the subwoofer in the
spot where you will normally sit, and then walk
around the room until you find a spot where the
subwoofer sounds best. Place the subwoofer in that
spot. Follow the instructions of the subwoofer’s
manufacturer, or experiment with the best location for
a subwoofer in your listening room.
