3 Overview The Yarden 4-C Closed-back Ceiling Speaker consists of a pair of high performance closed back speakers. Mount your Yarden 4-C speakers to the ceiling in one of two ways: either directly onto the ceiling or, for added protection, secure the speakers safely, using our ceiling mounting kit that is provided free (see Section 5.3).
4 Your Yarden 4-C Closed-back Ceiling Speaker Figure 2 defines the Yarden 4-C.
Each Closed-back Ceiling speaker is supported by a C-ring and two tile rails. The tile rails prevent the speakers from falling if the tile itself comes out or falls apart, as their ends catch onto the T-grid. When mounting onto the ceiling tiles, use both supports. When mounting onto a sheetrock ceiling, the C-ring alone is used to reinforce the ceiling material. i Be sure that the tiles can support the speaker. Smaller sized tiles or fiberglass-type tiles cannot support the weight of the speakers.
5 Installing the Yarden 4-C This section explains how to install the Yarden 4-C closed-back ceiling speakers, that is: 5.1 Choosing the best place to locate your speakers (see Section 5.1) Cutting the ceiling tile (see Section 5.2) Mounting the speakers (see Section 5.3) Setting up an array installation (see Section 5.4) Painting the speakers (see Section 5.5) Choosing the Best Location Ideally, locate the speakers above the main listening area.
4. Route the wiring from the amplifier to the speakers’ cutout holes, taking care not to place them next to electrical wires or at least at a distance of about two feet from an AC line. ! Do not nail or staple the speaker wires. If you are mounting the speakers onto a ceiling tile, remove the ceiling tiles where you plan to install the speakers. Use the template to trace and then cutout the speaker hole over an empty box.
T-channel Grid C-ring Support Ring Screws Ceiling Tile Tile Rails Figure 4: Mounting the Yarden 4-C Closed-back Ceiling Speaker 2. Place the tile rails on the tile and snap them into the two tabs on the C-ring. Align the rails so that the ends extend over the T-channel grid. 3. Insert a screw through each tab on the C-ring to secure the rails. 4.
Figure 5: Plugging and Securing the Cable 7. Push the speaker into the ceiling hole until the front baffle rim is leveled with the ceiling. 8. Tighten the mounting tabs by turning the screw counter clockwise (see Figure 6). Turning one quarter of a circle rotates the tab outwards; after that the screw is turned to tighten the tabs to the rear side of the ceiling surface When tightening the mounting tabs, the tabs automatically turn outward, thus clamping the speaker to the wall from its rear side.
Figure 7: Adjust Tap Selector 11. Install the grilles to the speakers: Push the grille fastener into the hole in front of the baffle Press the grille into place until the front of the grille is flush with the rim of the baffle i 5.4 Check that the grille is securely seated To remove the grille, insert two bent paper clips into the holes in the grille and carefully pull it down. Repeat this around the perimeter of the grille until it is completely removed.

5.5 Painting the Speaker You can paint the speakers before or after they are installed. When painting before installation: Clean the rim and grille with mineral spirits or other light solvent that is unlikely to damage the surface Spray with color by holding the spray can at an angle of 45 i When spraying the grille, take care not to clog the holes in the grille as this will greatly reduce the sound quality of the speakers.
