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 prob-
lem with installed speakers of more conventional design.

Preparation
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.
Optional items:
•Awire snake for running speaker cord behind wallboard
•Asturdy 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 loca-
tion 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.

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,” begin-
ning on page 13.

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. Con-
sider 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

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
• For ceiling installation, pay attention to the direction of the speaker enclosure for best per-
formance for stereo (Figure 6a) or for home theater (Figure 6b).

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.

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.
• All electrical wiring, vents, and plumbing pipes located inside the walls must be avoided
(Figure 8). Check with a trained professional if you need instructions on how to locate and
avoid them.

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
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).

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 run-
ning speaker cord through
studs or joists
• 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.

13
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 back-
ward 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 junc-
tion 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 /
2feet (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 base-
boards 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 condition-
ing vents.
AM267565_01_V.pdf May 13, 2003

14
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
If you must route cord around a corner, you will need to cut out a rectangular piece of wall-
board 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 com-
pound to hold them in place. When they are dry, sand and paint the area to match surround-
ing surfaces.

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.
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.
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.
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.
Wherever special instructions apply to ceiling or round-faced speaker installation, those
instructions will appear in a gray box, like this.
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 main-
tain 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.
AM267565_01_V.pdf May 13, 2003

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).
4. Remove the template.
Figure 14
Preparing to cut a pilot hole
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.

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.
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. Center the tip of the drill bit in the top circle you have drawn).
2. 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. 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.

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. Bend the wire as shown in Figure 17.

places
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. Make a mark 41 /
8inches (10.5 cm) from the short end as an indicator of the proper front-
to-back depth of the hole.
3. 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 /
8inches (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
• 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.

Steps to Installing
Figure 19
Checking the space for the
width of the speaker
• 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.
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.
Figure 20

wire (a) and sweeping from
side to side to check the
length (b)
• If the wire goes in and sweeps from side to side at the far end without a problem, pro-
ceed to the next major step: “Prepare the wall for inserting the speaker” starting on
page 21.
• If you find an impediment below the pilot hole, and you are working in an interior wall,
reinsert the wire upward. If there are no impediments above the pilot hole, you can
install the speaker upside-down. If you are working in an exterior wall, installing the
speaker upside-down is not recommended. In this case, if you find an impediment you
need to drill a new pilot hole elsewhere. Then repeat the preceding steps 3, 4, and 5.
Round-faced speakers require an additional 2 inches of clearance above the speaker.

Steps to Installing
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 con-
fused with the dogleg clamp screws that are labeled WALL (Figure 21). Those screws hold
the dogleg clamps on the frame.
Figure 21
Removing the speaker
frame to reorient it as
needed
• If you cannot insert the entire length of the wire straight up in an interior wall, and
sweep it from side to side as shown on the template, you need to drill a new pilot hole
elsewhere. Then repeat the preceding steps 3, 4, and 5.
Repairing a pilot hole
If you need to patch the pilot hole, you can fill it with spackle. You may need to let the spackle
dry, then add more until the hole is slightly overfilled. When it is thoroughly dry, sand the area
to bring it back flush with the wall.
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” starting on page 15 and repeat those steps.
If the location for the first speaker is fine, but the second is not, you may want to relocate
both speakers.
Round-faced speakers require additional clearance holes on either side of the main
speaker hole. If you have marked but have not drilled those holes yet, do so when it is clear
you will be installing a speaker in that spot.
