JBL Synthesis SAM1HF - Manual (Page 4)

Positioning your loudspeakers properly is critical in order to achieve the
sonic performance of a home theater. Please read the following section
for guidance in correct and optimal placement.
L EFT AND R IGHT S PEAKERS : If you have purchased a Synthesis Array
Module digital home theater system, then one of the configurations of the
SAM1HF/SAM2LF modules will serve as your front left and right main
speakers. Please see the Configuration and Connection diagrams in the
“SAM1HF and SAM2LF Configuration and Assembly” section to
correctly configure your main speakers.
Since the left and right speakers have been designed for maximum local-
ization of sound, they should be placed with the center of the speakers at
about the same height on screen as the actors would be, to aid in the illu-
sion that the actors’ voices are coming directly from their on-screen images.
Ideally, the speakers will be placed about 45 degrees apart from each other,
viewed from the listening position, so that the distance between the speakers
is the same as each speaker’s distance from the listener (see Figure 1).
C ENTER C HANNEL S PEAKERS : Please see the Configuration and
Connection diagrams in the “SAM1HF and SAM2LF Configuration and
Assembly” section to correctly configure your center speaker. Regardless
of the configuration you have chosen, it is important to place the horn
array vertically during installation in order to take advantage of its sound-
dispersion characteristics. If you mount it horizontally, it will not provide the
correct dispersion pattern. If the speaker is being used with a perforated
projection screen, it should be mounted behind the center of the screen
(see Figure 2).
If a nonperforated projection screen, plasma display or other fixed video
device is being used in the installation, then the recommended location is
directly below (and as close as possible to) the video display (see Figure 3),
although the inverse of this method will work also.
