HD OG.book Page 4 Tuesday, July 8, 2003 3:43 PM Introduction English Before you begin... Please be sure to read this guide carefully before you do any cutting. There are many factors to consider when choosing a location for your speakers. Thank you for choosing to install Bose® Virtually Invisible® 191 speakers in your room. Innovative engineering and advanced design enable these speakers to deliver Bose quality performance for big impact in spite of their small size.
HD OG.book Page 5 Tuesday, July 8, 2003 3:43 PM Preparation Unpacking Check to be sure the carton includes all the parts shown in Figure 2. Note: Now is a good time to find the serial numbers on the back of each speaker. Copy those numbers onto your warranty card and in the “For your records” space on page 3.
HD OG.book Page 6 Tuesday, July 8, 2003 3:43 PM Preparation English Wear clothing appropriate for the job, and consider using a drop cloth or other material to protect the area from debris. How and where you install the speakers will determine your need for optional equipment.
HD OG.book Page 7 Tuesday, July 8, 2003 3:43 PM Preparation Accessories that can help For installation in new construction, Bose offers a Rough-in Kit (Product Code #031353) for two speakers. It is designed for use after the studs are in place and before the wallboard is added to reserve a place for the speakers and indicate where the wallboard hole should be made. It also protects the wallboard by providing additional support for the dogleg clamps that secure the speaker to the wall.
HD OG.book Page 8 Tuesday, July 8, 2003 3:43 PM Preparation Installing in an exterior wall English If you choose to install these speakers in an exterior wall (abutting the outside of your house), you will undoubtedly 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.
HD OG.book Page 9 Tuesday, July 8, 2003 3:43 PM Preparation Select the general wall area for one speaker As you decide where you want each speaker grille, use the guidelines below: • The two speakers should be a minimum of 5 feet (1.5 m) apart. • For in-wall speakers providing stereo at the front of the room or home theater surround sound from the rear, install them so each speaker grille is 4 to 6 feet (1.2 to 1.8 m) from the floor for best performance.
HD OG.book Page 10 Tuesday, July 8, 2003 3:43 PM Preparation English • Each speaker enclosure extends into the wall or ceiling, as shown in the gray DO NOT CUT area on the template (Figure 7), and below the grille. The speaker enclosure can be inserted either up or down. Note: In cold climates where a humidifier is used, avoid inserting the speaker upside-down in an exterior wall to prevent problems with condensation.
HD OG.book Page 11 Tuesday, July 8, 2003 3:43 PM Preparation Using speaker cord To do so, measure the distance from the receiver/amplifier to where each speaker will be installed. Make some allowance if the cord must go around corners or through walls, and leave at least 14 inches (36 cm) of cord to pull from the wall for making the connections easily. Note: If you are installing ceiling speakers, allowing extra cord will give you the freedom to stand on the floor while making the connections.
HD OG.book Page 12 Tuesday, July 8, 2003 3:43 PM Preparation You also need to observe safe and practical standards: English WARNING: Make sure the spot chosen is safe for drilling. Do not drill through surfaces that may have hazards, such as electrical wiring, conduits, or plumbing concealed behind them. Follow all other safety precautions. • Consult local building codes to inform yourself of the requirements in your area. • Use a drill bit large enough for the cord you will pull through the holes.
HD OG.book Page 13 Tuesday, July 8, 2003 3:43 PM Preparation Before the wallboard goes up There are some standard guidelines for working in unfinished construction. • Snap a chalk line across the face of the studs or the bottom of the joists and move backward as you drill, so you can keep the last hole drilled in your line of sight. • Never run speaker cord and electrical cable through the same hole or into the same junction box.
HD OG.book Page 14 Tuesday, July 8, 2003 3:43 PM Preparation English Getting started Choose a path for the cord that avoids impediments to drill through. Use a stud finder to identify inaccessible studs. It is common to run cord from the speaker location in a wall or ceiling to the attic and through the wooden top plate that runs horizontally across the top of the vertical studs. From the attic, you can then run the cord to the spot above the junction box near the receiver or amplifier.
HD OG.book Page 15 Tuesday, July 8, 2003 3:43 PM Steps to Installing Before you make any holes Installation is basically the same, whether you are using these speakers with a rectangular grille or round grille and installing in a wall or ceiling. There are a few exceptions. Wherever special instructions apply to ceiling or round-faced speaker installation, those instructions will appear in a gray box, like this.
HD OG.book Page 16 Tuesday, July 8, 2003 3:43 PM English Steps to Installing 2. Center the pilot-hole circles on the selected spot as you press the template to the wall. 3. Use a pencil to trace around the inside of the circles (Figure 14). Round-faced speakers require additional clearance holes on either side of the speaker hole. Draw those circles as well as the pilot hole circles now.
HD OG.book Page 17 Tuesday, July 8, 2003 3:43 PM Steps to Installing Drilling the pilot hole Using the proper equipment and protection is important. WARNING: Use eye protection and be sure to observe all safety precautions while using the drill or cutting tool (Figure 15). Figure 15 Caution against drilling without eye protection WARNING: Make sure the spot chosen is safe for cutting. Do not cut through surfaces that may have hazards such as electrical wiring, conduits, or plumbing concealed behind them.
HD OG.book Page 18 Tuesday, July 8, 2003 3:43 PM Steps to Installing Testing the space behind the hole English You need a tape measure and a sturdy wire (such as a straightened coat hanger) 22 inches (55.9 cm) in length for this step. 1. Bend the wire as shown in Figure 17. Figure 17 A 22-inch (55.9 cm) length of sturdy wire bent in two places 3 inches (7.6 cm) 141/4 inches (36.2 cm) 41/8 inches (10.
HD OG.book Page 19 Tuesday, July 8, 2003 3:43 PM Steps to Installing Figure 19 English 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. Round-faced speakers require an additional 2 inches of clearance above the speaker. • 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. Now remove the wire. 5.
HD OG.book Page 20 Tuesday, July 8, 2003 3:43 PM Steps to Installing English Note: To position the logo right-side-up if you insert the speaker upside-down, remove the outer frame from the face of the speaker, rotate it 180˚, then reattach the frame. There are four speaker frame screws, labeled GRILLE, that hold the frame in place. They should not be confused with the dogleg clamp screws that are labeled WALL (Figure 21). Those screws hold the dogleg clamps on the frame.
HD OG.book Page 21 Tuesday, July 8, 2003 3:43 PM Steps to Installing Prepare the wall for inserting the speaker CAUTION: Now is a good time to reconsider your comfort level with this job. If you have doubts about cutting into or running cord behind the wall, it’s best to stop here. Then you can contact a professional installer, describe the job, and request a cost estimate before engaging the installer’s services. WARNING: If you believe insulation in a wall may contain asbestos, do not cut into the wall.
HD OG.book Page 22 Tuesday, July 8, 2003 3:43 PM Steps to Installing English Tip: 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. For ceiling installation, notice the orientation of the Bose® logo on the speaker frame. Make sure it will be oriented as you want it when you position the speaker in the hole you cut.
HD OG.book Page 23 Tuesday, July 8, 2003 3:43 PM Steps to Installing 2. Cut around three of the four sides of the outline you drew, not all the way around (Figure 24a). English WARNING: Keep fingers away from the cutting blade. Figure 24 3. Hook your finger into the pilot hole and then make the final cut (Figure 24b). 4. Using your finger, pull out the piece of wallboard you have just cut.
HD OG.book Page 24 Tuesday, July 8, 2003 3:43 PM Steps to Installing English Figure 25 Pulling the wire up and out, to the left At least14 inches (36 cm) of wire 2. Use tape or the assistance of another person to temporarily affix the loose end of the wire above and to the left of the hole (Figure 26). 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.
HD OG.book Page 25 Tuesday, July 8, 2003 3:43 PM Steps to Installing Use both hands to support the speaker and angle it slightly, so it is diagonal to the hole. This allows clearance for the wall stops. 2. Insert the bottom of the enclosure through the hole and down part of the way – or up, depending on your clearance issues (Figure 27). Dogleg clamps Dogleg clamps Partially inserting the rectangular-faced or roundfaced speaker English Figure 27 1. Wall stop Wall stop 3.
HD OG.book Page 26 Tuesday, July 8, 2003 3:43 PM Steps to Installing Make the speaker connections English You need a Phillips-head screwdriver for this step. Tip: 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.
HD OG.book Page 27 Tuesday, July 8, 2003 3:43 PM Steps to Installing To test the speaker: 1. Turn on the receiver/amplifier and play a piece of music that is familiar to you. Listen for clarity and accuracy of the performance from one speaker. • If you hear a problem, refer to “Troubleshooting” starting on page 32. • If the performance sounds fine, test the other speaker, or continue with the installation steps for this speaker.
HD OG.book Page 28 Tuesday, July 8, 2003 3:43 PM Steps to Installing Secure the speaker to the wall English CAUTION: If you use a screw gun to tighten any screws, first select the gun’s lowest torque setting (do not exceed 2-4 inch-pounds or 0.2-0.5 N-m of torque). If the screw does not seat properly, finish installing the screw at the next highest torque setting, or by hand.
HD OG.book Page 29 Tuesday, July 8, 2003 3:43 PM Steps to Installing 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 33). 5. 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.
HD OG.book Page 30 Tuesday, July 8, 2003 3:43 PM Steps to Installing Painting the grille English It is important to prevent paint from clogging the grille perforations, which can adversely affect performance. You can use a dry brush technique or choose to spray paint the grille. Do not use a paint roller, however. Regardless of the technique you choose: • Remove the grille from the speaker if it has been installed. • Before you begin to paint, clean the grille to remove possible contaminants.
HD OG.book Page 31 Tuesday, July 8, 2003 3:43 PM Steps to Installing 2. English Steps for spray painting: 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. Apply the paint to the grille surface at a 45˚ angle. Then rotate the grille by 180˚ and repaint it at 45˚.
HD OG.book Page 32 Tuesday, July 8, 2003 3:43 PM Reference English 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.
