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
