Nederlands Italiano Français Deutsch English PREPARATION Deciding on speaker placement The design of your new Virtually Invisible® 191 speakers makes them well-suited to either wall or ceiling installation. The location you choose will affect the procedure for installing them.
English Deutsch Français Italiano Nederlands PREPARATION CAUTION: When installed, the speaker enclosure cannot be seen behind the wall or ceiling. Do not attempt to nail, cut, or drill on that surface area. Puncturing the speaker enclosure with a tool will seriously damage the speaker.
Nederlands Italiano Français Deutsch English PREPARATION • Place the in-wall center channel speaker above or below the video screen, centered between, but not on horizontal center with, the left and right front speakers. If a line were drawn between the left, center, and right front speakers a “V” shape would be created. • The speakers should not be installed sideways in a wall; the enclosure should be either above or below the speaker face.
English Deutsch Français Italiano Nederlands STEPS TO INSTALLING Before you make any holes Be sure you have read and understand the considerations provided in “Preparation” starting on page 5, so you can proceed with confidence. CAUTION: If you are unsure of your ability to complete this process, contact a professional installer. Small check marks call your attention to the tools you’ll need for the next step. Tips offer ideas to make the job go easier and help you avoid mistakes.
Nederlands Italiano Français Deutsch English STEPS TO INSTALLING Drilling the pilot hole You will need a half-inch spade bit and power drill, or a special rotary cutting tool for this step. WARNING: Use eye protection and be sure to observe all safety precautions while using a drill or cutting tool (Figure 8). Figure 8 Caution against drilling without eye protection WARNING: Make sure the spot chosen is safe for cutting.
English Deutsch Français Italiano Nederlands STEPS TO INSTALLING Testing the space behind the hole 7LS You need a tape measure and a sturdy wire (such as a straightened coat hanger) 22 in. (55.9 cm) in length for this step. 1. Bend the wire as shown in Figure 10. Figure 10 A 22-inch (55.9 cm) length of sturdy wire bent in two places 3 in. (7.6 cm) 141/4 in. (36.2 cm) 4 1/8 in. (10.5 cm) 4 3/4 in.
Nederlands Italiano Français Deutsch English STEPS TO INSTALLING Figure 12 Checking the space for the width of the speaker 360° • If the wire goes around the 360° arc without a problem, proceed to step 5 below. • If you cannot rotate the wire all the way around up to the first bend, you need to drill a new pilot hole elsewhere. Then repeat the preceding steps 3 and 4. 5.
English Deutsch Français Italiano Nederlands STEPS TO INSTALLING Passing the pilot hole test If you have successfully determined that this location will work for one speaker, test the wall or ceiling for the second speaker before making any larger holes. Refer to “Drill a pilot hole for testing the wall space” on page 9 and repeat those steps. If the first speaker location is fine, but the second is not, you may want to relocate both speakers.
Nederlands Italiano Français Deutsch English STEPS TO INSTALLING 4. Make a dotted line, using the slotted holes along the bottom of the WHITE CUT-OUT AREA portion, for the bottom edge of the hole. 5. Remove the template. 7LS If necessary, use tape to hold the template temporarily in place (see TAPE HERE on the template). Then run your pencil along the entire template edge, except where there is tape.
English Deutsch Français Italiano Nederlands STEPS TO INSTALLING If you encounter insulation behind the wall You can expect to find insulation in an exterior wall and sometimes in an interior wall. If the insulation found there is malleable, you can cut and remove some of it from both above and below the speaker hole to make room for the speaker. Other types of insulation will be difficult or possibly dangerous to handle. CAUTION: Beware of hidden nails when reaching into the wall to remove insulation.
Nederlands Italiano Français Deutsch English STEPS TO INSTALLING Figure 18 Pulling the wire up and out, to the left (a) and securing it with tape (b). At least 14 in. (36 cm) of wire 2. (a) (b) Use tape to temporarily affix the loose end of the wire above and to the left of the hole (Figure 18b). This keeps the wire out of the way until you have the speaker partially inserted in the wall and are ready to make the connections.
English Deutsch Français Italiano Nederlands STEPS TO INSTALLING Make the speaker connections You need a Phillips-head screwdriver for this step. 7LS Pay attention to maintaining the proper polarity (+ to + and – to –) with these connections. An error here will adversely affect speaker performance. Also be sure to tighten each screw securely, but not enough to cause undesirable compression of the wire. 1. If you have not done so earlier, loosen the screws on both terminals. 2.
Nederlands Italiano Français Deutsch English STEPS TO INSTALLING Figure 22 2. Make sure the frame of the speaker is firmly screwed onto the face. The frame prevents the speaker from slipping all the way into the hole. Refer to Figure 17 on page 15 if you need to reverse the frame to orient the Bose logo on the rectangular speaker face. 3. Push the speaker into the hole until the face is straight and flush with the wall (Figure 22b).
English Deutsch Français Italiano Nederlands STEPS TO INSTALLING Attaching rectangular grille frames 1. Line up the curved edge of the grille with the curve over the Bose® logo and press that edge into the speaker frame first (Figure 24). 2. Press the top of the grille firmly into place until you feel some resistance. When the grille lines up flush with the frame of the speaker, it is seated properly.
Nederlands Italiano Français Deutsch English REFERENCE Painting the speakers The grille and frame of your Virtually Invisible® 191 speakers can be painted before or after the speaker is installed. This is optional, however, and Bose cannot be responsible for the quality of adhesion or finish of non-factory applied paints. There are different techniques for painting the grille and painting the frame. Be sure to use paint that is appropriate to the technique you choose.
English Deutsch Français Italiano Nederlands REFERENCE 1. To prevent dirt or dried paint particles from blowing back into the grille perforations, suspend the grille or place it on a wire screen. 2. Apply the paint to the grille surface at a 45° angle. Then rotate the grille by 180° and repaint it at 45°.
Nederlands Italiano Français Deutsch English REFERENCE Accessories that can help For installation in a drop ceiling (where tile is installed below the ceiling joists), Bose offers an optional Drop Ceiling Kit for two speakers. It protects the tile from bearing the weight of the speakers. Instructions are included with the kit. For installation in new construction, Bose offers a Rough-in Kit for two speakers.
English Deutsch Français Italiano Nederlands REFERENCE • Never run speaker cord and electrical cable through the same hole or into the same junction box. • If a short section of the cord must run parallel to nearby electrical cable, keeping that run to the absolute minimum will result in less interference. • Use metal conduit or shielded speaker cord if the cord must run next to electrical cable for 10 ft. (3 m) or more.
Nederlands Italiano Français Deutsch English REFERENCE What to do when the room is not pre-wired In this case, you will need to run speaker cord from the receiver or amplifier through the wall to the area you have chosen for installing the speakers. You will need to mount an open-backed junction box in the wall near the receiver or amplifier (Figure 28). You also need to observe safe and practical standards: WARNING: Make sure the spot chosen is safe for drilling.
English Deutsch Français Italiano Nederlands REFERENCE Figure 29 Studs Techniques to use for running speaker cord through studs or joists Wire Staple Nail plate 3-4’ (1-1.3m) Plumb line for chalk mark Speaker cord Electrical wire If you must route cord around a corner, you will need to cut out a rectangular piece of wallboard on either side of the joist at that corner. Use each regular-shaped cutout as the patch for the wall when you finish.
Nederlands Italiano Français Deutsch English REFERENCE Installing in an exterior wall If you choose to install these speakers in an exterior wall (abutting the outside of your house), you may encounter insulation behind the wallboard. This can complicate the installation, requiring you to trim and push malleable insulation out of the way. You will need to wear eye protection and gloves for working with fiberglass insulation.
English Deutsch Français Italiano Nederlands REFERENCE Troubleshooting Neither speaker plays • Check the settings on your receiver/amplifier. Refer to the owner’s guide that came with it for instruction on settings. • If your Virtually Invisible® 191 speakers are the second pair of speakers connected to your receiver/amplifier, make sure the connections have been made to the “B” terminals and that the “B” speakers are selected to play.
Nederlands Italiano Français Deutsch English REFERENCE Accessories • Drop Ceiling Kit for two speakers Protects the tile from bearing the weight of the speakers. Instructions included. • Rough-in Kit for two speakers Reserves a place for the speakers after the studs are in place and before the wallboard is added, and indicates where the wallboard hole should be made.
