In-Wall Speaker System

Thank you for choosing NXG Signature Series 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 (Fig. 2)

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. A void
mounting speakers in stud cavities containing electrical wiring, heating ducts, water pipes, etc. Make sur e
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 listening area.

Pivoting Tweeters (Fig. 3)

The tweeters in all NXG Signature Series speakers may be adjusted, allowing you to focus the speakers’
high frequency output 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.

Tweeter/Midrange Level Adjustments (Fig. 4)

Tweeter and midrange level controls allow you to tailor the speakers’ frequency response to better
match the room’s acoustics. As an example, if a room has a hardwood floor, which makes it acoustically
brighter sounding, you may want to adjust the tweeter and midrange levels to compensate. You can
experiment with both levels to find the sound that’s most pleasing to you in your particular listening
environment.

Speaker Installation In Existing Construction (See Fig. 5 on reverse)

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 Signature Series 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 outside 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 location.
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. 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. 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 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.)

NXG Signature Series In-Wall Speakers can be used

as rear surround sound channels by placing them

(1) behind, (2) on each side of viewer, or (3) in the

ceiling just behind viewing position. They also make

excellent front channel home theater speakers (4).

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.

6. See Fig. 6. With the speaker wire attached to the speaker, slide
the speaker up inside the cut-out hole. Center the speaker in the
cut-out hole and turn the six locking screws clockwise until the
speaker is drawn up snugly to the wall board from behind, clamp­ing the speaker in place. Try to tighten each screw equally. Replace
the speaker grill by gently pressing it into place.

New Construction (A)

Note: Use of optional new construction rough-in bracket kits will
not only save time but will also enhance the sound quality of your
installed speakers. (See rough-in kit installation manual for mount­ing instructions when using kits.)

New Construction (B)

(Mounting without use of new construction rough-in brackets.)

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 every­thing 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 or movie source
such as FM, a CD or DVD player. Gently turn up the volume, you
should hear sound coming from your new NXG speakers. If no
sound is heard from any or all speakers, switch off the system
immediately and check for open or loose connections, wrong
polarity or shorts, or proper source selection.
