Tip
The distance between the center speaker and the
listening position B cannot be more than 1.5 meters
(5 feet) shorter than the one between the listening
position and the front speaker A. Place the speakers
so that the difference in the length of B in the
diagram below is no more than 1.5 meters (5 feet)
shorter than the length of A.
Example: Adjust the distance B to 4.5 meters (15
feet) or more when the distance A is 6 meters (20
feet).
Also, the distance between the surround speakers/
surround back speakers and the listening position
C cannot be more than 4.5 meters (15 feet) shorter
than the distance between the listening position and
the front speakers A. Place the speakers so that the
difference in the length of C in the diagram below
is no more than 4.5 meters (15 feet) shorter than the
length of A.
Example: Adjust the distance C to 1.5 meters (5
feet) or more when the distance A is 6 meters (20
feet).
This is important because incorrect speaker
placement is not conductive to the enjoyment of
surround sound. Place note that placing the speakers
closer than the required will cause a delay in the
output of the sound from that speaker. In other
words, the speaker will sound like it is farther away.
