INTRODUCTION
StageFront Home Theater Solutions loudspeakers are expressly designed
for superior sonic quality in home theater applications. Each model employs
advanced technology components that extract the subtle nuances in recorded
music or the thunderous action sound in a movie. Models ending in “LCR” are
intended primarily for front channel left/center/right placement or wherever a
monopole design is required. Models that end in “FX” are designed for special
effect placement. StageFront models are the perfect choice wherever quality of
sound is the most important consideration.

TOOLS AND PRECAUTIONS
We recommend using the following tools to install an In-Wall StageFront
loudspeaker:
■ Electric drill with 1/4- and 1/2-inch drill bits, and a 1-inch flat drill bit (for drilling
through studs)
■ Keyhole or drywall saw
■ Stiff wire, fish tape, or glow rods (for routing cables)
(CONTINUED ON NEXT PAGE)

INSTALLATION CONSIDERATIONS
■ Phillips screwdriver set
■ Cable ties
■ Pencil
■ Level
■ Rubber gloves and protective eyewear
(CONTINUED)
Before starting the installation, please observe the following precautions:
■ Turn off all system power before making any connections
■ Always wear protective eyewear when using tools
■ Make sure hands are clean before installation
■ Wear gloves when working with fiberglass insulation
RECOMMENDED AMPLIFIER POWER
For satisfactory performance, we recommend using an amplifier with a power
rating of 15 to 125 watts. Most loudspeakers are not damaged by large amplifiers,
but rather by small amplifiers. If your system is playing loud music, a small
amplifier will run out of power very quickly and can create damaging “clipping”
distortions. A more powerful amplifier will play at the same volume without
distorting. See OPERATION on page 11 for more information about amplifier
clipping distortion.
LOUDSPEAKER WIRE
Use 2-conductor loudspeaker wire when connecting loudspeakers to your
receiver or amplifier. For most applications, we recommend using 16-gauge wire.
For wiring runs longer than 80 feet, we recommend 14-gauge wire. The springloaded terminals will accommodate up to 12-gauge wire directly. Larger sizes can
be accommodated via pin connectors. When running wire inside walls or ceilings,
use special jacketed cable (CL-2 or CL-3) to protect the wire and to meet local
electrical and fire codes. In some areas, conduit is also required. For a trouble-free
installation, low-voltage wire such as loudspeaker wire must be run in accordance
with the National Electrical Code and any applicable provisions of the local
building code. If you are unsure of the correct installation techniques, wire jacket,
or type of conduit to use, consult a professional audio/video installer, building
contractor, or the local building and inspection department.
TECH TIP
Wire size is expressed by its AWG (American Wire Gauge)
number – the lower the number, the larger the wire. For
example, 12 AWG is physically larger than 14 AWG.
