Bose® Virtually Invisible® 191 Speakers May 13, 2003 AM267565_00_V.pdf Bose Corporation Safety Information Important words of caution WARNING: Installation shall be in accordance with the applicable section of the National Electrical Code, ANSI/NFPA 70, and/or the National Fire Alarm Code, ANSI/NFPA 72, as applicable. The wiring method and compartment shall be such as not to interfere with the operation of the speaker. CAUTION: Consult local building codes before you get started with this installation. Please read this owner's guide completely before you start. Then carefully consider your experience with using the tools and taking the precautions referred to here. CAUTION: Failure to follow the instructions in this owner's guide voids all warranties on your speakers. If you have doubts about doing this installation, you should contact either the dealer you purchased the product from, an electrician, or a professional audio/video installer. You can describe the job and request a cost estimate before committing to installation service. 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. Use these instructions with wood frame or similar construction only Each speaker requires 8 1/16 inches (20.5 cm) of horizontal space, and 14 inches (35.6 cm) of vertical space inside the wall or ceiling, plus a minimum of 4 1/8 inches (10.5 cm) of depth from the face of wallboard that is a maximum of 1 inch (2.5 cm) thick. Bose recommends installing these speakers only in wood frame or similar construction where there is enough space between studs, as is found in 2 x 4 or 2 x 6 wall/ceiling construction.

AM267565_01_V.pdf May 13, 2003 3 Introduction 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. Virtually Invisible® 191 speakers feature an Articulated Array® speaker configuration that delivers the type of clear, lifelike sound and even coverage known as Bose Stereo Everywhere® speaker performance. What makes this speaker better also makes it different When installed, Virtually Invisible® 191 speakers take up very little wall space. What isn't apparent is their advanced enclosure design, shown in Figure 1. It ensures predictably fine performance wherever the speakers are installed, regardless of the size and shape of the wall space. It also helps prevent the speaker sound from invading other rooms, a common problem with installed speakers of more conventional design. Figure 1 Size and shape of the speaker enclosure, as shipped with the rectangular frame attached Rectangular grille Speaker frame screws Rectangular speaker frame Speaker face Dogleg clamps Dogleg clamp screws Speaker enclosure 4 AM267565_01_V.pdf May 13, 2003 Carefully unpack the speakers. Save all packing materials, which provide the safest means to transport your speakers as needed. If any part of the speaker pair appears damaged, do not use the pair. Notify Bose or your authorized Bose® dealer immediately. For Bose contact information, refer to the address list included in the carton. Note: Now is a good time to find the serial numbers on the side of each speaker. Copy those numbers onto your warranty card and in the "For your records" space on page 3. Hardware for securing the speaker to a wall or ceiling comes attached to the speaker. But you will need a variety of other equipment, including tools, to prepare the surface for installing the speakers (Figure 3).

How and where you install the speakers will determine your need for optional equipment. Optional items: · A wire snake for running speaker cord behind wallboard · A sturdy stool or ladder for installing speakers above your head · Gloves and protection for your mouth, nose, and eyes for working with insulation Consider which shape you prefer for your speakers The design of your new Virtually Invisible® 191 speakers makes them well-suited to either wall or ceiling installation. You also have a choice of a rectangular or round speaker face ­ the part that is visible when the speaker is installed. Consider which shape will work best in the location you choose for the speakers. If you prefer the round shape, it is easy to remove the rectangular frames and replace them with the round frames provided in the carton. You can do it now or wait until you know for sure where each speaker will fit. However, be sure to make that change before you insert either speaker into the wall or ceiling. Note: The lip of the speaker frame prevents the speaker from slipping behind the wall and out of reach. Do not remove the frame while the speaker is in the wall. Figure 4 Replacing the rectangular speaker frame with the round frame If you choose the round frames, use the round template provided in the carton. A round paint shield is also supplied, in case you decide to paint the speaker. Considering your wall type and the approach it requires For working in a pre-wired room of finished construction with 2 x 4 stud walls covered with wallboard, refer to "Steps to Installing," beginning on page 15. These instructions cover installation of the speakers, with either a rectangular or round grille, in a wall or ceiling. If your installation is different, use the information below as it applies. 6 AM267565_01_V.pdf May 13, 2003 Preparation 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 (Product Code #031355) 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 (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. Instructions are included with the kit. For more information or to order an accessory, contact your Bose® dealer. Or, to contact Bose directly, refer to the address list included in the carton. Use special care in cutting through plaster and lath For wall construction of plaster and lath, use special care to prevent plaster from cracking: · After you have drawn an outline of the hole to cut, tape around the outline and use a sharp blade to make shallow cuts where the hole will be. · Then, within the outline only, chip the plaster away until you expose the lath underneath. · Finally, cut through the lath very carefully. Using an electric sabre saw can be quick but risky. We recommend using a hand saw and proceeding cautiously to avoid damaging the surrounding plaster. Installing in a pre-wired room An installation is simplest when the room has been pre-wired during construction. In that case, the builder will have left speaker cord within easy reach of the intended speaker positions. How to determine pre-wiring If you are not sure that you have a pre-wired room, or do not know where the wiring is located, check the architectural drawings of your room or call the builder. CAUTION: It is important to know where the pre-wired cord is to prevent damaging it while drilling or cutting into the wall. In the ideal situation, after cutting the speaker hole you can simply reach inside to locate the length of cord the builder has installed. 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. If you have not done this before, be sure you understand the steps involved before you get underway. Having a friend who can help with this step is advisable, too. Information on running speaker cord in new construction is provided in "Before the wallboard goes up," beginning on page 13. For running speaker cord inside finished walls, refer to "Where the walls are finished," beginning on page 13. AM267565_01_V.pdf May 13, 2003 7 Preparation Installing in an exterior wall 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. WARNING: If you believe the insulation inside a wall may be composed of asbestos, do not cut into the wall. Choose a different location for the speakers instead. Insulation will also impede your use of a pilot hole to test the size of the space behind the wallboard. Doing such a test is recommended to make sure the space is large enough before cutting a speaker-sized hole. Special considerations in cold climate regions With exterior wall installations in regions where outdoor temperatures dip below freezing for days at a time, using a humidifier can cause condensation to form inside the speakers. This can be more of a problem if the speakers are mounted upside down. If you must mount in an exterior wall: · Avoid installing the speakers upside down. · Leave some of the insulation between the speakers and the exterior wall. · Refrain from setting the humidifier on high, especially when outside temperatures are below freezing. Deciding on speaker placement How and where you use the speakers will also affect your procedure for installing them. Consider the options below, then follow the instructions that apply to your choices: · How you will use the speakers? ­ for stereo sound at the front of a room or seating arrangement, or ­ as home theater front speakers, or ­ as surround sound speakers at the rear of your viewing area · What surface you will install in? ­ a wall or ceiling ­ if a wall, will it be an interior (abutting another room) or exterior (abutting the outside surface) wall ­ in finished or new construction ­ if finished, is it plaster and lath or wallboard construction 8 AM267565_01_V.pdf May 13, 2003 Preparation Select the general wall area for one speaker As you decide where you want each speaker grille, use the guidelines below: CAUTION: Do not install near any heat sources, such as halogen lamps, registers, stoves, or other apparatus (including amplifiers) that produce heat. · 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. · Neither speaker should be installed sideways in a wall; the enclosure should be either above or below the speaker face. · For in-wall home theater front speakers, install the pair horizontally aligned with the center of the video screen (Figure 5). Figure 5 Orienting wall speakers for front home theater use 5´ (1.5m) · For ceiling installation, pay attention to the direction of the speaker enclosure for best performance for stereo (Figure 6a) or for home theater (Figure 6b). Figure 6 Orienting ceiling speakers for the best coverage (a) for stereo or (b) for home theater front and surround (a) View of ceiling from below Front of room Rear of room (b) View of ceiling from below · Height guidelines for in-wall speakers do not apply to ceiling installations. AM267565_01_V.pdf May 13, 2003 9 Preparation · 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. Allowing enough room both above and below the hole you draw provides a fallback in case the area below your pilot hole is not suitable for the speaker enclosure.

Preparation Using speaker cord Before you cut any cord, estimate how much will be needed for each speaker. 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. Be sure to use the proper gauge (thickness) of speaker cord, determined by the length of each piece. Wire recommendations Based on a maximum frequency response deviation of ±0.5 dB Gauge 18 AWG (0.82 mm2) 16 AWG (1.3 mm2) 14 AWG (2.1 mm ) 2 Maximum Length 20 ft (6 m) 30 ft (9 m) 50 ft (15 m) CAUTION: Before running speaker cord through a wall or under a floor, check your local building code requirements and safety regulations. If necessary, contact an A/V installer or electrician for this information. Prepare the cord You will need a wire cutter and wire stripper for this work. Speaker cord consists of two insulated wires. The insulation around one wire is marked (striped, collared, or ribbed) to identify it as positive. The other wire is negative. It is important to connect each wire to the proper terminal, positive to positive (+) and negative to negative (­). Note: It is sometimes difficult to distinguish wire markings. Inspect both wires carefully. At the ends of each cord: · Strip approximately 1/2 inch (13 mm) of insulation from both wires. · Twist the bare end of each wire so loose strands will not touch across terminals. Planning to run speaker cord The techniques for running cord differ according to the condition of the walls you are working with: new, unfinished construction or finished construction with the walls completed. In either construction type, you need to mount an open-backed junction box in the wall near the receiver or amplifier for cord coming out of the wall (Figure 9). Figure 9 An open-backed junction box that allows for cord coming through the wall near the receiver or amplifier AM267565_01_V.pdf May 13, 2003 11 Preparation You also need to observe safe and practical standards: 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. · Use an auger bit, if possible, to make the work of drilling multiple holes less tiring. · Do not drill through a load-bearing beam. Consult the building contractor if this is an issue. · Keep the cord 3 to 4 feet (1 to 1.3 m) away from electrical cord, which can create a hum or buzz in the speakers (Figure 10). · To avoid nails, drill holes in the center of each stud or joist. · Use a nail plate to protect the cord if your only option is to notch a stud or joist. Figure 10 Techniques to use for running speaker cord through studs or joists Nail plate Speaker cord Wire staple Studs 3-4 (1-1.3 m) Plumb line for chalk mark Electrical wire · Line up holes as perfectly as possible to make pulling the cord through easier. · Keep the cord taut enough so there are no sags. · Do not pull the cord tight enough to create tension. 12 AM267565_01_V.pdf May 13, 2003 Preparation Before the wallboard goes up There are some standard guidelines for working in unfinished construction. · Begin this work after the studs and joists are in and the electrical wiring is completed. · 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. · 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 feet (3 m) or more. · Use cable clamps or large wire staples to fasten the cord to a joist or stud wherever the cord runs more than 41/2 feet (1.4 m) from a hole. · Use protective guardstrips, raceways, or conduits to protect the cord from being stepped on or compressed in an attic or crawl space. Where the walls are finished Here are some suggestions for how to make this job easier. Look for ways to conceal cord outside the walls: · Along or behind baseboards · Under carpets (using special flat speaker cord for under-the-rug speaker runs) · Under doorjams (Figure 11). Figure 11 Running cord behind baseboards and a doorjam Find the easiest path for cord that must run behind the wallboard: · Choose interior walls, which are less likely to have insulation packed behind the wallboard. · Use an attic or basement run where possible, so you have easy access and can see where plumbing, electrical wires, and other impediments occur. · In slab construction, consider using plenum-rated wire run through heating or air conditioning vents. AM267565_01_V.pdf May 13, 2003 13 Preparation 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. Drill through the top plate at that point and route the cord through the hole and down into the wall (Figure 12). Figure 12 Running the cord up through the attic Top plate Open-backed junction box 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. By reaching through the cutout, you can notch the joist to make room for the cord and use nail plates to cover the cord in each notch (Figure 13a). To patch the wall, reposition the cutout pieces (Figure 13b) and use joint tape and joint compound to hold them in place. When they are dry, sand and paint the area to match surrounding surfaces.

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. CAUTION: If you are unsure of your ability to complete this process, contact a professional installer. Allow 30 to 60 minutes to complete the steps that follow. Drill a pilot hole for testing the wall space Before you make a sizeable cut into the wallboard, check the space by probing behind the wall or ceiling through a small pilot hole. Time spent now can help ensure a successful installation. Note: If you are working in an exterior wall where there is insulation, it may be difficult to probe behind a pilot hole. You may prefer to eliminate this step and skip ahead to "Prepare the wall for inserting the speaker" starting on page 21. Do this only if you can be sure the insulation is malleable and that nothing else behind the wall will impede the installation. WARNING: If you believe the insulation behind the wall may be composed of asbestos, do not drill or cut into that wall. Find a different location for the speakers instead. Using the template for this first step You will need a sharp pencil for this step. The template is designed to show where to drill two half-inch (13 mm) pilot holes first, before you make an opening large enough for the entire speaker. This allows you to probe behind the wall to make sure your chosen location is spacious enough and there are no unseen materials blocking the installation. Notice the dotted lines extending at an angle from the pilot hole to the bottom corners of the DO NOT CUT area on the template. Use them as a guideline for testing the area below the pilot hole to make sure it is spacious enough behind the hole for the length and width of the speaker enclosure. To position the template 1. Select a spot on the wall or ceiling where you want the center of the speaker grille. For ceiling installations, carefully consider how the position of the speaker enclosure behind the wallboard affects the orientation of the Bose® logo on the speaker face. To maintain a consistent logo orientation, you can remove and rotate the speaker frame as needed before inserting the speaker into the ceiling hole. See Figure 21 on page 20. Tip: Remember to allow enough space for the speaker enclosure both above and below the pilot hole. You may need that second option if you find an impediment in the space below the hole. This does not apply to exterior walls in cold climate regions, where upside-down speaker installation is not recommended. AM267565_01_V.pdf May 13, 2003 15 Steps to Installing 2. 3. Center the pilot-hole circles on the selected spot as you press the template to the wall. 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. However, you may prefer to drill those holes only after you have successfully explored behind the pilot hole and know there are no impediments to installing the speaker there. 4.

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. Follow all other safety precautions. 1. 2. Center the tip of the drill bit in the top circle you have drawn). Drill completely through the wallboard to create a hole that you can probe behind. Note: If you encounter insulation in the wall, it will be difficult, if not impossible, to probe behind the pilot hole. If you are certain that the location you have chosen is free of hazards and impediments, you may choose to cut the hole for the speaker anyway, remove some of the malleable insulation, and proceed from there. Refer to "Prepare the wall for inserting the speaker" starting on page 21. 3. Figure 16 Using a spade bit with the power drill to create the pilot hole Drill the second hole just below the first one (Figure 16). This elongates the hole enough to allow for testing the space for the length of the speaker enclosure. AM267565_01_V.pdf May 13, 2003 17 Steps to Installing Testing the space behind the hole 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.

Tip: For greater accuracy, make the first bend a little long, measure again, and cut off the extra length at that end. WARNING: If there is a possibility of electrical wiring in the space behind the wallboard, wrap the wire with electrical tape to prevent electric shock. 2. 3. Make a mark 41/8 inches (10.5 cm) from the short end as an indicator of the proper frontto-back depth of the hole. Use the bent wire to test for enough depth, front-to-back: Insert the short end of the wire into the hole and straight back (Figure 18). Probe to make sure nothing impedes inserting this end to a depth of 41/8 inches (10.5 cm). This indicates that the space behind the wallboard is deep enough for the front-to-back speaker dimension. Figure 18 Checking the space for the depth of the speaker 4 / 8" ) 5 cm (10. 1 1 4 / 8" ) 5 cm (10. · If the wire goes in without a problem, proceed to step 4, below. · If you cannot insert the wire to the 41/8-inch (10.5 cm) mark, you need to drill a new pilot hole elsewhere. Then repeat step 3. 4. Use the wire again to test the width, side-to-side: With the short end still in the hole, reposition it (as shown in Figure 19) and rotate it 360° around the hole. This indicates if the wall space is wide enough on each side of the hole for the side-to-side dimension of the speaker. 18 AM267565_01_V.pdf May 13, 2003 Steps to Installing Figure 19 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. Use the long end of the wire to check for enough length below the hole: Holding the short end of the wire, insert the long end into the wall or ceiling and straight down from the hole (Figure 20a). Tip: You may want to use the template for this step, as shown in Figure 20b. With the long end of the wire still in the hole, sweep it from side to side in a curve as shown on the template. This indicates if the wall or ceiling space is long enough and wide enough at the far end. Tip: When testing for length, move the wire near the wall or ceiling, then farther back from it.
