Where To Place Your In-Wall Speakers
Placement can make all the difference in how your speakers sound, and how easy they will be to
install. Carefully consider where your speakers should be positioned. For optimum performance,
speakers should be mounted to the left and right of the main listening position and a minimum of 8
to 10 feet apart (See Fig. 2). Avoid mounting speakers in stud cavities containing electrical wiring,
heating ducts, water pipes, etc. Make sure the wall or ceiling materials are sturdy enough to support
the weight of the speakers.
In-Wall Placement: Optimum performance will be achieved when your speakers are mounted at ear
level or slightly higher. If you desire to mount them higher in the wall, turn the speaker over so the
tweeter is closer to the listening area.
In-Ceiling Placement: Optimum performance will be achieved when your speakers are mounted to
the left and right of the main listing area.
Adjustable Tweeters
(Fig. 3)
The tweeter in your NXG speaker may be adjusted, allowing you to tailor the speaker to better fit the
listening area. The overall smoothest response is achieved with the tweeter facing straight out: how-
ever, you may find the sound more pleasing by aiming tweeters toward a particular listening area. To
adjust the tweeter, apply pressure on the ring surrounding the tweeter with your thumb or finger.
Speaker Installation In Existing Construction (See Fig. 4)
Once you have selected the location for your speakers, you are ready to install them.
You will need the following:
Stud Finder Drill & Drill Bits Wire Cutter/ Strippers
Pencil Utility Knife or Drywall Saw Small Level
Masking Tape Phillips Screwdriver Speaker Wire
NXG recommends the use of 16-gauge wire minimum. For wire options consult your retailer or
custom audio contractor.
1. NXG In-Wall Speakers are designed to be installed in the wall area between studs. Using a stud
finder, make sure you are between two studs. Using the supplied template and a level to ensure your
template is straight, tape the template to the wall and lightly trace around the inside with a pencil.
2. Cut the hole using your drywall saw. You may want to start with a small hole in the center of
the outline. This will allow you to check for any obstructions that may exist behind the desired loca-
tion. CAUTION: Be certain electrical wiring, water pipes or heating ducts do not interfere in the
planned installation areas prior to drilling or cutting the wall.
3. Run speaker wire from your amplifier or speaker switching device to the speaker location.
4. Carefully remove the grille and inner grille backing. (Note: The open cell foam inner grille backing
is designed to hide speaker components from view and may be removed if desired.) If you like the
standard white finish of your NXG speakers, skip to step 5, but if if you want your speakers to blend
in with a colored wall or ceiling, now is the time to paint your speaker’s outer frame and perforated
grille. (Remove the foam inner grille backing and put it aside in a clean and dust free area for later
reinstallation if desired.) The speaker’s outer surface will accept ordinary latex wall paint or aerosol
spray paint. Because the speaker baffle surface behind the grille should remain unpainted, you will need
to cover this area with the supplied cardboard paint mask. Cover the speaker’s interior black surface,
woofer and tweeter. Paint the outer speaker frame and grille separately. (Grille painting hint: Use a paint
roller that is nearly out of paint to first paint the inside of the grille, then the outside. This will avoid
paint filling the grille perforations.)
5. Attach the wire to the input terminals on the rear of the speaker. Remember to maintain proper
polarity with the amplifier by attaching the positive (+) lead to the red terminal and the negative (-)
lead to the black terminal.
Congratulations on choosing NXG In-Wall Loudspeakers. Like all NXG products, great care has been
