Speaker Placement
Distributed Audio (SM55 and SM55 SST)
The SM55 and SM55 SST’s low installation profile makes them
ideal for use in distributed audio systems. They provide coverage
of a very wide listener area, allowing them to be mounted in a
wide variety of installation locations.
Because a single SM55 SST speaker reproduces both stereo
channels from a single location, it will deliver outstanding
performance from a wide variety of mounting locations where a
pair of stereo speakers would be impractical, including hallways,
bathrooms and closets.
The table and illustration below show how far apart the speakers
can be placed at various ceiling heights while still providing good
coverage for all listeners.

Surround Channel (SM55)
The SM55’s low-profile design and wide area coverage also
make it an excellent choice for surround channel applications in
home theater systems.
5.1-Channel System
(see
Figure 2
)
• Locate the left and right surround speakers on the ceiling
between 2 feet and 6 feet behind the listening position. The
speakers should be between 6 feet and 10 feet apart.

(see
Figure 3
)

Place the left and right sur-
round speakers directly to the sides of the listening position,
between 6 feet and 10 feet apart.
•
SS uu rr rr oo uu nn dd BB aa cc kk SS pp ee aa kk ee rr ss ::
Place the surround back speakers
between 2 feet and 6 feet behind the listening position. The
surround back speakers should be closer together than the left
and right surround speakers — between 3 feet and 6 feet
apart.
Before Installation
1. Determine the location for the speaker (see
Speaker
Placement
).
2. The SM55 and SM55 SST Mounting Plates (available sepa-
rately) are designed to install onto a J-box (single or double)
that has already been mounted in the ceiling.
