Installing the Loudspeaker

The WS320 and WS350 In-Wall Loudspeaker Systems re­quire at least 3-3/4 inch of wall depth, including the wall­board. They can be mounted into a wall surface with a
thickness between 3/8 inch and 1 inch.

Tools and Fasteners Required:

Phillips Screwdriver Tape Measure
Drywall Saw or Knife Stud Finder
Pencil Bubble Level
Cable Ties

Parts Included:

Loudspeaker Baffle (1) Baffle Box (1)
Frame (1) Frame Gaskets (2)
Grille (1) Grille Fasteners (10)
Cutout Template (1) Painting Mask (1)
Clamping Pieces (2) Baffle Washers #8 (6)
Airtight Electrical Connector (1)
Frame Screws #10-24 x 3 inch (6)
Baffle Screws #10-24x 1-1/2 inch (6)

Optional Part:

RK320 Rough-In Bracket (designed to provide a cutout
and mounting frame for installation during new construc­tion).

Use of Paint Mask

Set the Paint Mask between the baffle and grille to paint
the grille and frame without getting paint on the baffle and
Loudspeaker Elements.

Installing the Frame

The Frame Assembly consists of the frame and two clamp­ing pieces, held together with six 3 inch screws. These
screws are fully extended to allow pushing the clamping
pieces toward each other so the whole assembly fits into
the cutout.

Note: If the optional RK320 Rough-In Bracket has already

been installed, go directly to step 3.

1. Hold the supplied cutout template against the wall and
align it using the bubble level. Tape the aligned tem­plate to the wall and trace the opening on the wall.

2. Cut out and remove the piece of wallboard. Pull
enough Loudspeaker Cable to be able to connect it to
the Loudspeaker Baffle while the baffle is still out of
the wall.

3. Install the two L Shaped self adhesive Frame Gas­kets to the rear of the frame so that it will be between
the frame and the wall. Insert the right side of the as­sembly into the hole and push it to the right. This will
give enough room to insert the left side of the assembly
into the wall. Center the assembly in the opening.

4. Push the right side Clamping Piece up against the
backside of the wallboard. Tighten the now protruding
center screw enough to gently hold the frame in place.
Repeat on the other side of the frame.

5. Use the bubble level to assure the frame is correctly
positioned, and then tighten all the screws until the
frame is securely attached to the wallboard.

Note: To avoid crushing the wallboard, do not over tighten the

screws. If the mounting position places the frame near a
stud, remove the clamping piece and secure the frame
directly to the stud, through the provided holes.

Installing the Baffle Box

Before setting the Baffle Box into the frame, run the Loud­speaker Wire through the supplied Airtight Electrical Con­nector and tighten the connector onto the Loudspeaker
Cable. Be sure to pull enough wire through the connector
to allow connection to the crossover network on the back
of the Loudspeaker Baffle while it is still out of the wall.
Set the Baffle Box into the frame.

Note: The Baffle Box may be positioned with the Airtight

Electrical Connector either at the top or bottom.

Connecting the Loudspeaker

The McIntosh WS320 and WS350 In-Wall Loudspeaker
Systems utilize Binding Posts for Loudspeaker Cable Con­nections.

1. Connect a Loudspeaker Cable from the black or nega­tive Loudspeaker Binding Post on the back of the
Loudspeaker Baffle to the negative or common output
terminal of one channel of the amplifier.

2. Connect a Loudspeaker Cable from the red or positive
Loudspeaker Binding Post on the back of the Loud­speaker Baffle to the positive or 4 ohm output terminal
of the same channel of the amplifier.

Note: Be sure to tighten the Loudspeaker and Amplifier

Binding Posts after connecting.

Installing the Loudspeaker Baffle

Place the Loudspeaker Baffle into the frame/box assembly
and screw it into place using the six supplied screws. Hold
the baffle in place until at least two screws are properly se­cured.

Note: Secure excess Loudspeaker Cable away from woofer

cone with cable ties.

Installing the Grille

Press onto each Loudspeaker Grille the supplied Rubber
Grille Fasteners, with three per side, two on the top and
bottom edges of the grille. Press the perforated metal grille
into the gap between the baffle and frame. Press all around
the edge until the grille sits flush with the frame.
