INTRODUCTION  
Before you begin...  
CAUTION: Please be sure to read this guide carefully before you do any cutting. There are many  
factors to consider before proceeding with this type of installation.  
Thank you for choosing to install Bose® Virtually Invisible® 191 speakers. 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 speaker 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.

PREPARATION  
Unpacking  
Carefully unpack the speakers. Check to be sure the carton includes all the parts shown in  
Figure 2. If any part of the speaker pair appears damaged, do not use them. 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 back of each speaker and copy the  
numbers onto your warranty card and in the “For your records” space on page 2.

will need a variety of other equipment and tools to install the speakers (Figure 3).

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.  
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 surround sound rear speakers  
• What surface will you install them in?  
• an interior wall (abutting another room), or exterior wall (abutting outside), or ceiling  
• in finished (plaster and lath or wallboard), or new construction  
Three tips for determining speaker placement  
1. The template can be placed against a wall or ceiling to help determine the amount of  
space the speaker will need. Each speaker enclosure extends into the wall or ceiling, as  
shown in the gray DO NOT CUT area on the template (Figure 4). In a wall, the speaker  
may be inserted either up or down and will extend either above or below the grille.  
2. Use of a stud finder can help ensure that the speaker hole is at least 43  
a stud or joist.  
/
4 in. (12 cm) from  
3. All electrical wiring, vents and plumbing pipes located inside the walls must be avoided  
(Figure 5 on page 7). Check with a trained professional to learn how to locate and avoid  
them.  
Note: To prevent problems with condensation in cold climates where a humidifier is used, avoid  
inserting the speaker upside-down in an exterior wall.
