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.

Consider which shape you prefer for your speakers

You 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. Typically, the rectangular shape is best suited for walls and the round shape is best
suited for ceilings.
It is easy to remove the rectangular frames and replace them with round frames. 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. 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. See "Reorienting or changing speaker
frames" on page 15 for instructions for removing and replacing speaker frames.

Considering your wall type and the approach it requires

If you are installing the speakers in a pre-wired room of finished construction with 2 x 4 stud
walls covered with wallboard, the placement of your speakers has already been determined.
Please refer to "Steps to Installing" on page 9. 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 to help determine where to place
your speakers. 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.

For placement in walls

• The two speakers should be a minimum of 5 ft. (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 so each speaker grille is 4 to 6 ft. (1.2 to 1.8 m) from the floor for
best performance.
• For in-wall home theater front speakers, install the pair horizontally aligned with the center
of the video screen (Figure 6 on page 8).
