NXG Technology NX-PRO6820CE - Manual (Page 3)

FIG. 6
NXG recommends the use of 16-gauge wire minimum. For wire options, consult your retailer
or custom audio contractor.
1. NXG Architectural Speakers are designed to be installed in the ceiling area between studs.
Using a stud finder, make sure you are between two studs. Trace around the outside of the
template 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. 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 speak -
er’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. The NX-PRO6820CE has a metal security loop on the rear of the enclosure. You can use wire
rope to secure the unit to a solid structural part of the building to provide extra protection in
case of a ceiling failure or earthquake.

Adjustable Tilt-Swivel Tweeter Island (Figs. 5A and 5B)
The tweeter island in the NX-PRO6820CE ceiling speaker can be directed toward the listening
area, allowing you to tailor the speaker’s dispersion pattern to better fit the desired listening
area. The overall smoothest response is achieved with the tweeter island facing straight out;
however, you may find the sound more pleasing by aiming the tweeters toward a particular
listening position. To adjust the tweeter island direction, you can rotate the tweeter housing
clockwise or counterclockwise (a maximum of 180 °) as shown in Fig. 5a.
Adjust the tweeter island’s angle by holding it on either side of the long axis and tilting the island
toward the desired listening position (a maximum of 20 ° each direction) as shown in Fig. 5b.
Speaker Installation In Existing Construction (Fig. 6)
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 • Speaker Wire
• Pencil • Phillips Screwdriver • Utility Knife or Drywall Saw • Masking Tape
6. Be sure to set the transformer tap switch to
your desired value. Note: 8 ohm setting for typical
stereo/surround receivers, desired tap for distrib-
uted 70 volt systems.
7. 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.
8. See Fig. 7 (next page). 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 four 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.
