You can reduce sound transmission to adjacent rooms and fur-
ther improve speaker performance by inserting a sheet of
unfaced fiberglass insulation over the back of the speaker. To
reduce noise produced by unsupported drywall, install fiberglass
insulation in the ceiling bays adjacent to the speaker location.

For installations where it is not possible to section-off the ceiling
bay to form a back box (such as when you are retrofitting the
speakers into an existing ceiling), you can effectively reduce
sound transmission into adjacent rooms by fitting the speakers
with Large Round and Square Retrofit Enclosures (part # 92243).
This enclosure will noticeably reduce sound “spillover” from the
rears of the speakers into adjacent rooms and spaces.
Installing the Speakers

For installations in new construction, Sonance recommends using
a Flex bracket (part# 92247) to reserve a location for the speak-
er. The Flex bracket is nailed or screwed to the studs and serves
as a guide for the drywaller so that the speaker hole will be in
the desired location once the drywall is installed.
Flex brackets are compatible with the RotoLock™ mounting sys-
tem.

1. Determine the location for the speaker (see
Speaker Placement
on page 1).
2. Perform an obstruction survey to be certain that there are no
studs, conduit, pipes, heating ducts or air returns that will
interfere with the speaker.
3. The cutout for Original Series SST speaker is 101
/8” (257mm).
There also must be at least 6” (152mm) depth within the ceil-
ing cavity for the speaker.
4. Position the included cutout template where the speaker is to
be located and pencil an outline on the ceiling.
• If you are unsure about obstructions, drill a small hole in
the center of the outline and insert a coat hanger wire into
the hole to feel-around for possible obstructions.
5. Cut the hole using a drywall saw, and run the speaker wires.

Sonance Original Series SST speakers feature exclusive
FastMount™ tabs and an integral RotoLock® mounting system for
quick mounting directly into existing ceilings and walls.

1. Remove the paint plug from the speaker. Connect the speaker
wire to the terminals on the speaker. Double-check that you
connected amplifier + to speaker + and amplifier – to speak-
er –.
2. Make sure all the RotoLock clamps are in the full clockwise
position so that they are tucked within the mounting hole’s
border. Insert the speaker into the hole in the ceiling. The
RotoLock system can accommodate a maximum ceiling mater-
ial thickness of 1¼” (32mm).
• The FastMount tabs will prevent the speaker from falling out
of the mounting hole, allowing the installer to let go of the
speaker to pick-up tools or other items (see
Figure 1
).

3. Tighten the four screws on the front of the speaker baffle. The
RotoLock clamps will automatically rotate into position and
begin clamping the speaker (see
Figure 1
).
• When you notice resistance on the screws the speaker has
been clamped successfully.

4. Attach the grille after the speaker has been installed. Insert
about half of the grille into the groove at the edge of the
speaker. Gently fit the remaining half of the grille by working
around the speaker, fitting the grille into the groove as you go.

Painting The Speakers and Grilles
You can paint the speakers and grilles before installing them,
which will eliminate the “paint scar” if the speaker ever needs to
be removed for service. You can also paint the speakers after
installation, but before the grilles are attached. Original Series
SST speakers come from the factory fitted with a plastic ‘paint
plug’. Use the paint plug to protect the speaker drivers while the
flange is being painted along with the wall.
Sonance suggests always painting the grille separately from the
speaker. Before painting, carefully remove the under-grille cloth.
It is held in place with a light tacking glue that makes it easy to
remove.
Spray the grilles with thinned paint (5 parts thinner to 1 part
paint), being careful not to plug the holes. Too heavy a coat of
paint on the grille will adversely affect the sound of the speaker.
Once the grilles and flange are painted and dry, replace the
under-grille cloth, remove the paint plug from the speaker flange
and install the grille.
