Speaker Placement; Left And Right Speakers; Center Channel Speakers - JBL SCL-3 Owner's And Installer's Manual

SPEAKER PLACEMENT

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.

LEFT AND RIGHT SPEAKERS

If you have purchased a Synthesis home theater system, then the SCL-3 or SCL-4 models could serve as your front
left and right main speakers. Since they have been designed for uniform coverage and maximum dispersion 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 illusion that the actors' voices are coming directly from their on-screen images. Ideally, the speakers will be
placed about 60 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 (Figure 1). Although their acoustic coverage area
allows mounting the systems in any of the four possible orientations where necessary (horn located above, below, or
to the sides of the woofers), the preferred orientation is with the horn above the woofer(s). This will depend greatly on
mounting location height and room boundaries.

CENTER CHANNEL SPEAKERS

SCL-4: If you have purchased the SCL-4 for the center position, be sure to place it vertically (horn above or
below woofer) during installation in order to take advantage of its sound-dispersion characteristics. If you mount it
horizontally, it will not provide the most optimized horizontal dispersion pattern. If the speaker is being used with a
perforated projection screen, it should be mounted behind the center of the screen with the horizontal "center" axis
aligned as close as possible to the center axis of the Left and Right channel speakers (See Figure 2).
