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.
