Also, the distance between the surround speakers/
surround back speakers and the listening position
C cannot be more than 4.5 meters (15 feet) closer
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
following diagram is no more than 4.5 meters (15
feet) closer 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.
