8˝ Rock Speaker System
Congratulations on
choosing your Elura
rock speakers. Like
all Elura products,
great care has been
taken in their de-
sign. Their combi-
nation of advanced
engineering and
state-of-the-art
materials will pro-
vide you with years
of listening pleas-
ure. The speakers were designed to appear like naturally
occurring landscape rocks. The realistic rock-like shape
and the availability of two natural colors (Granite & Sand-
stone) allow them to blend into almost any outdoor envi-
ronment 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).
Where to Place Your Rock Speakers
Elura 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 bushes, plants
,
and
other landscape settings. When determining placement
you should
first consider the ease of running 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
speakers 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
distortion
and possibly damaging your speakers. If you
are using
more than two speakers to cover a large area,
we recommend you consult your receiver/amplifier
owner’s manual
to determine how many 6 ohm speakers
can be connected
to each channel of its outputs. Most
receivers are only
rated for one 6 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. 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 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 elec-
trical 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 deter-
mined 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 installa-
tion 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.
(See Fig. 4 on reverse for speaker connection detail)
• Strip the outer jacket from each end of the cable about 3 inches and
expose the two insulated conductors.
• Strip
1
/
2
˝ of insulation from the end of each conductor.
• Twist the positive wire to the Red wire and the negative wire to the Black
wire of the speaker.
• Make sure the two connections do not touch each other for the next step.
