MR/SSMR/MSQ

• Place the left and right speakers anywhere from 6 feet to 10

feet apart, with the main listening position as close to midway
between the speakers as possible.

• In most cases pivoting the woofer of each speaker directly

towards the main listening position will help maximize the
stereo soundstage.

Use the Left and Right speaker placement in 

Figures 2 and 3

(on page 1) as a guide.

Before Installation: Retrofit

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, pocket doors or air returns
in the ceiling cavity that will interfere with the speaker.

3.  The cutout for all Merlot MR, MSQ and SSMR speakers is 5

”

(149mm) in diameter. There also must be at least 3½” (89mm)
depth within the ceiling 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 mounting hole using a keyhole or drywall saw, and

run the speaker wires from the mounting hole to the amplifier
location.

• Consult local building codes before running speaker wires

through ceilings.

Installation

Sonance Merlot speakers feature exclusive FastMount

®

tabs and an

integral RotoLock

®

mounting system for quick mounting directly

into existing ceilings. 

WARNING: THE EDGES OF THE FASTMOUNT TABS
ARE VERY SHARP. USE CAUTION WHEN 
HANDLING THE SPEAKER.

1. Remove the paint plug from the speaker. 

2. Run speaker wire from each speaker to the amplifier location. 

3. Strip ¼” – ½” of insulation from each speaker lead. Twist the

strands or tin the exposed wire with solder to ensure that there
are no stray strands. (Stray strands that touch each other can
cause a short-circuit that can damage the amplifier.)

4. The speaker’s connector posts are spring-loaded. Push the top

of each connector post down to open the connector and insert
the exposed wires into the holes in the posts. 

• The speaker’s positive post is labeled with a red dot; the 

negative post is labeled with a black dot. Double-check that
you connected amplifier “+” to speaker “+” and amplifier “–”
to speaker “–”. 

5. 

Make sure all the
RotoLock clamps are in
the full clockwise posi-
tion so that they are
tucked within the
mounting hole’s bor-
der. Insert the speaker
into the hole in the
ceiling (

Figure 4). The

RotoLock system can
accommodate a maxi-
mum ceiling material
thickness of 1¼”.

• 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
(

Figure 5).

6. Tighten the four screws

on the front of the
speaker baffle. The
RotoLock clamps will
automatically rotate
into position and begin
clamping the speaker
(

Figure 6).

• 

When you notice
resistance on the
screws the speaker
has been clamped
successfully.

7. Attach the grille after the speaker has been installed. Insert

about half of the grille into the groove at the edge of the speak-
er. Gently fit the remaining half of the grille  by working around
the speaker, fitting the grille into the groove as you go.
