Where to Place Your Rock Speakers
The NX-PRO6500 rock speakers are designed to be placed
directly on the ground in your landscape, on a deck, or
patio. Since they imitate naturally occurring rocks, they
blend in best if placed near other rocks and among bush-
es, plants and other landscape settings. When determin-
ing placement you should first consider the ease of run-
ning your speaker wire from the amplifier location to each
speaker and the sound coverage area you desire from
each speaker. (Note: Do not place speakers in a low-lying
area where water may accumulate since they are not
designed to be submersed in water.) If possible, all speak-
ers should be placed at the same elevation to obtain the
most balanced sound reproduction. Placing speakers at
different heights will alter the speakers’ combined sound
characteristic. Each speaker should cover a 90 degree pie-
shaped listening area in front of the speaker’s face, which
is the grille side (See Fig. 2).
Speakers should face the listening area and the spacing
between units should be approximately 10 to 20 feet apart
(see Fig. 2). Measure the listening area you want to cover
to determine the number of speakers you will need to give
adequate sound coverage. Using the correct number of
speakers for proper coverage is better than turning the
volume of the receiver up beyond its limits, causing distor-
tion and possibly damaging your speakers. If you are using
more than two speakers to cover a large area, we recom-
mend you consult your receiver/amplifier owner’s manual
to determine how many 8 ohm speakers can be connected
to each channel of its outputs. Most receivers are only
rated for one 8 ohm speaker per channel. If you need to use
more than two speakers per channel, we recommend using
an impedance matching speaker selector or a impedance
matching volume control such as the NX-VM80. Using one
of these impedance matching devices will assure the safe
operation of your amplifier if multiple pairs of speakers
are being used. (See Fig. 3 on reverse.)
Tools & Materials Required for Installation
Wire strippers
Spade or trenching tool/shovel
Hacksaw or pipe cutter
PVC conduit, cleaner, glue, & cutting tool (optional)
Tube of silicone sealant
Direct burial rated speaker cable with polarity marking
on the cable
16AWG minimum for cable runs up to 70 feet
14AWG for cable runs of 70 - 120 feet
12AWG for cable runs of 120 - 170 feet
Running the Speaker Cable and Connecting the Speaker
If you chose to bury your speaker wire, we recommend you first consult your
local utility companies (phone, electric, cable TV, gas, water, or other applicable
organizations) for any buried cables or utility line locations before you begin to
dig. You may also need to consult your local building and electrical codes for
any applicable requirements.
Once you have determined the desired location of your speakers and where any
buried obstructions may exist, you can dig the trench for your wire. Lay your
cable on top of the ground along the path you have determined to each speaker.
If not using conduit, you may dig a narrow trench or slit the ground below the
grass line along the wire path and tuck the wire in. If you are using conduit, size
and cut it to fit the trench first. Then assemble the conduit and associated parts
with PVC cleaner and glue according to the manufacturer’s instructions. Pull the
speaker cable through the conduit and lay the conduit into the trench. In either
installation style, make sure to leave approximately 2 or 3 feet of extra cable
under the speaker in case you need to adjust its location later.

Congratulations on choosing your NX-PRO6500 rock speakers. 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. The NX-PRO6500 speakers
were designed to appear like naturally occurring landscape rocks. The realistic rock-like shape
and the availability of two natural colors (Granite & Sandstone) allow them to blend into almost
any outdoor environment allowing you to create a natural looking outdoor audio solution.
Before you get started, it’s a good idea to identify all the parts and hardware (See Fig 1).
