In-Wall Speaker Systems
Congratulations on choosing NXG In-Wall Loudspeakers. Like all NXG products, great care has been
taken in their design. Their combination of advanced engineering and state-of-the-art materials will
provide you with years of listening pleasure, while blending smoothly into your home’s decor. Before
you get started, it is a good idea to identify all the parts and hardware (See Fig. 1).
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 ar
In-Ceiling Placement: Optimum performance will be achieved when your speakers are mounted to
the left and right of the main listing area.

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: however, 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:
n Stud Finder n Drill & Drill Bits n Wire Cutter/Strippers
n Pencil n Utility Knife or Drywall Saw n Small Level
n Masking Tape n Phillips Screwdriver n Speaker Wire
NXG recommends the use of 16-gauge wire minimum. For wire options consult your retailer or
custom audio contractor.

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.

New Construction
1. Determine speaker locations and mark them on
your plans for future reference.
2. If possible, run speaker wires after HVAC and
electrical wiring is in place.
3. Secure speaker wires in place along the run
with insulated staples only and be careful not to
pierce the wire’s insulation. Allow a bit of slack for
expansion of building materials.
4. Needless to say, the actual speakers should not
be installed until the wall board is in place. In the
meantime, leave several feet of wire coiled up and
secured at the back side of the mounting hole.
5. To complete the installation follow steps 2
through 5 above.
Operational Check
After making all connections it’s a good idea to
make sure every thing is working properly. Turn on
your surround or stereo system making sure the
volume control is turned down and that the balance
control is in the center position. Activate a musical
