iW4 ARC In-Wall Loudspeaker Installation Guide
Installation: Existing Construction (retrofitting finished ceilings)
This multi-step process begins by identifying a location in your wall (or ceiling) for the speaker (always keeping a plan B in mind). Some-
how you’ll need to get speaker wire to that spot. Using a stud-finder or something you will make sure there are no obstructions behind
your intended speaker location. Using the enclosed cutout template you will mark and cut a clean “hole” using a rotary cutter, sheetrock
or keyhole saw. After you have found and connected the speaker wire you will mount the speaker in the hole and snap on the magnetic
grill. It’s usually not as easy as this sounds and you should once again consider hiring a pro installer.
Warning: Exercise caution when drilling into existing walls and ceilings. Do not drill through electrical wires, pipes, drains, conduits,
heating or air conditioning ducts or structural wood or metal support members. If you feel resistance while drilling, you should stop im-
mediately. Do not install the speaker into a drop ceiling (T-Bar) or soft ceiling without a proper backing board to spread the load, as this
type of construction will not support its weight.
You will not need the iW4B pre-construction bracket nor will you be able to install it even if you wanted to. The speaker is designed to
mount securely without it (assuming you do everything right).
Tools You’ll Need:
#2 Philips screwdriver
Pencil
Tape measure
Utility knife or keyhole saw
Safety goggles
Dust mask
Protective gloves
A solid and stable ladder (maybe)
Electric drill with #2 Philips bit
Band-aids
. Using a “stud finder” or the “knocking” method, locate the wall studs (or ceiling joists) in the ceiling area where you wish to mount
the speaker. The speaker will be mounted between adjacent studs (or ceiling joists), no closer than two inches from either joist to allow
room for the dog-ear to swing into position.
2. Determine that there are no obstructions behind the desired cutout area. This may be accomplished by drilling a hole in the center
of the cutout area and using an “L” shaped piece of metal (like a bent coat hanger wire) to “feel around” the space. If you discover an
obstruction, fill the hole with patching compound and try another location (plan B).
