2. Use the side knockout when there is limited space above the ceiling.
3. Use both knockouts when an independent signal-in and signal-out wiring scheme is required and there is available space above the ceiling.

Wiring the Loudspeaker

Wire gauge requirements from loudspeaker line wiring to loudspeaker terminals: Use 18 AWG (0.8 mm2) to 14 AWG (2.5 mm2) size wire only.

Preparing the Installation

• Install the EM90-LP in a corner. See below for the room placement top view.
• Install the EM180-LP along a wall. See below for the room placement top view.

Loudspeaker Placement

When installing the loudspeaker near a wall-ceiling interface, allow sufficient space for the grille overhang. The grille must be flush with the ceiling surface so the magnets can fully engage. Use the enclosed template to ensure appropriate dimensions for the loudspeaker cutout and placement.

1. For EM90-LP or EM180-LP in ceiling tile: Place the loudspeaker opening at least 114 millimetres (4.5 inches) from each wall to allow space for the tile bridge.
2. For EM90-LP or EM180-LP in a hard ceiling: Place the cardboard template flush with the corner (EM90-LP) or wall (EM180-LP). This leaves at least 38 millimetres (1.5 inches) from each wall to accommodate the grille.

    

Using a Safety Cable

• Some regional construction codes require the use of a secondary method of securing loudspeakers to support structures to provide additional safety. Choose a mounting position, method, and hardware consistent with local building codes and regulations.
• Bose Professional recommends using (1) a safety wire, (2) a safety cable, or (3) a threaded rod as a secondary securing mechanism. See the diagrams below for safety attachment points.
• Follow the manufacturer’s instructions for any secondary securing mechanism implemented.

Assemble the Tile Bridge

1. Attach the four rails to the centre frame using four of the included screws.
2. Insert the screws from the inside of the tile bridge.
3. The rails and centre frame are labelled A and B to identify the correct attachment points.
4. Adjust the length of the tile bridge rails so the rails rest securely on the ceiling grid or furring.
   
5. Tighten the four screws securing the tile bridge rails to the centre frame.
6. Optional: Attach the L-brackets to the tile bridge to create an additional connection point for a safety wire, safety cable, or threaded rod

Preparing Tile

Cutting the Ceiling Tile

1. Remove the tile and use the template to trace a loudspeaker hole onto the tile.
2. To centre the template on the tile, draw an X by connecting the corners diagonally, and centre the template using the crossing point.
3. Cut a hole in the tile.

Installing the Tile Bridge

1. Place the assembled tile bridge across the ceiling grid. If necessary, adjust the tile bridge so the rails rest on the ceiling grid.
2. Replace the tile in the ceiling.

Cutting the Ceiling

1. Use the template to trace a hole in the ceiling.
2. Cut a hole in the ceiling.

Installing the Tile Bridge

Insert the assembled tile bridge through the hole and place the tile bridge across the ceiling grid or ceiling furring. If necessary, adjust the tile bridge so the rails rest on the ceiling grid or ceiling furring.

Mounting the Loudspeaker

1. Use a screwdriver and hammer to knock out the relevant wire opening.
2. Make sure the anchors engage on the tile bridge before loosening your grip on the loudspeaker.
3. Remove the connector, wire the connector, and reinsert the connector into the loudspeaker.
4. Tighten the anchor arm screws to secure the loudspeaker.
5. If using a power drill, set it to a low torque setting.
6. Discard the PhaseGuide protector.
7. Pass the audio wires through the wire opening and insert the loudspeaker through the hole in the ceiling and into the tile bridge.

Attaching the Grille
