INSTALLATION/OWNER'S MANUAL

Indoor/Outdoor 2-Way Rock Speaker

LUR652E-LUR65EW INTRODUCTION

Welcome

Congratulations on your purchase of the Dual Rock Speaker. A high level of design
experience and engineering went into creating the Dual Rock speaker. With the rugged
look of weathered granite, the Dual Rock 2-way speakers are extremely versatile and
are perfect when placed in areas ranging from indoor use like terrariums and interior
gardens to back yards, patios and pool or spa settings.

These weather resistant loudspeakers are made of the most durable components
including fiber-reinforced poly resin composite enclosures to achieve a product which
will resist rain, hail, sleet, coastal environments and snow, but still appear natural and
inconspicuous. You will find that the materials used in the Dual Rock are also superior in
resisting sun fade and water marks. The Rock speaker was specifically designed to look
and sound great for seasons to come.

Important

Although the Rock speakers are designed to resist weather and withstand unfriendly
environmental conditions, there are precautions you should take to optimize the long­term life and performance of your Dual Rock speakers. Keep soil, debris and woodchips
from covering the speaker grille. If debris accumulates on the grille, it can easily be
rinsed away with a garden hose using low water pressure. Do not spray water directly
into the face of the grille. Avoid placing the speakers where the grille area will come in
direct contact with sprinklers. If you desire to rinse the speaker surface, then direct the
spray of water at a 45 degree angle away from the grille, again using low water pressure.

Yard chemicals constitute another element that can prematurely shorten the speaker’s
life. Fertilizers, weed control sprays and many other chemicals commonly used in the
yard can potentially cause damage to the rubber and silicone speaker components of
the Rock.

LUR652E-LUR65EW INSTALLATION

Sound Coverage and Speaker Placement

The Dual ROCK speaker is sold separately, as many outdoor installations have multiple
zones. It is assumed for the purpose of this manual that the Rock speakers will be
installed using a minimum of two speakers. When deciding on the placement of your
Dual ROCK speakers, allow for a total coverage area of approximately 100 to 450 sq.ft. per
pair of Rock speakers. This is an estimate based on the ambient noise levels of a typical
outside patio or yard and your personal listening level. If you are using your speakers in a
high noise area where your sound coverage requirement is influenced by high automobile
traffic noise or located in close proximity to a heavily industrialized urban area; or If you
desire music over a physically large area, it is best to have a larger number of speakers
playing at low volumes, rather than a few speakers playing at high volumes. Multiple
pairs of speakers placed in strategic locations within your coverage area can be a
fundamental solution when designing an outdoor system that requires large coverage.

Ideally, you should place the speakers as close to the primary listening area and audio
source as possible. The volume of the speaker decreases rapidly as it is moved further
from the listener. Keep in mind that wire must be run to the location of the speakers.
Patios, walls, and other features in your yard may be difficult to get around when wiring
your speakers, so properly planning your design is important. Measure twice, dig once.

The grilles are not designed or intended to be removed. Do not remove the grilles from
your Rock speakers. There are no user serviceable parts behind the grille and removal
will damage the speaker.

LUR652E-LUR65EW CONNECTION

CONNECTIONS  - WIRE RUNS

Each Dual ROCK speaker has a two-conductor speaker wire surrounded by a cable
sleeve exiting the bottom of the speaker. The LUR652E has typical speaker leads in
this location. The LUR65EW model is designed with 50 feet of environmental rated wire
already attached. Regardless of the model purchased, any connection to the speaker
should be of a similar gauge wire (cable) running from the speaker location to your
audio system.

Dual does not supply speaker wire or cable accessories separately at this time. If you
are installing the LUR652E, you may wish to purchase certified direct burial cables
(environmentally rated speaker wire) and/or a watertight burial box which also works
well for the purpose of protecting your connection. Burial cable or wire rated for in
ground installation is available at most hardware stores and home improvements
outlets.

The cable or wire can be run either directly beneath the speaker into the ground, or you
can use the notch on the bottom edge of the speaker to exit the cable out the rear for
hard surface installations. When attaching the cable to the speaker, it is critical that a
high quality connection be achieved. Poor connections will lead to corrosion, possible
loss of signal and/or a decline in audio performance.

When possible, try to reduce the distance of your speaker from the audio source to
achieve the best audio results. The optimum run should be no longer than 50 feet
for the most favorable results. Runs longer then 50' are common, but may require
additional installation steps. Please ask your Dual dealer or a professional contractor if
you have questions regarding long wire runs. Dual recommends larger wire of 12 or 14
gauge for speaker wire runs longer then 50 feet.

LUR652E-LUR65EW CONNECTION

CONNECTIONS  - POLARITY

Caution: Do not attempt to connect the speakers to any source, amplifier or receiver that
is turned on. Be sure the receiver is off prior to connecting the speakers.

Parallel or series wiring is commonly acceptable for the Dual ROCK speakers to gain
correct amplifier loading. Avoid series wiring your Dual speakers with any other speaker
type or brand.

In phase installations will take special care to connect the speaker wire runs in phase
using the correct polarity.

Polarity - Speaker wires are marked for polarity consistency so that you can determine
the positive and negative identity of the individual wires within the molded pair insulation.
Polarity is shown by either a color stripe on the insulation, by ridges molded into one side
of the insulation, the color of the insulation case around the wire, or by the color type or
colors of the wires/wire itself (copper or silver).

Important: In order to maintain correct polarity, always connect speaker wire using the
positive(+) terminal on the receiver to the positive (+) wire, and the negative (-) terminal
on the receiver to the negative (-) wire.

For a typical audio installation, all speakers in a system will be connected with the same
respective polarity. The speaker connections are located on the bottom of the Dual ROCK
speaker.

For best results, crimp or solder the wires together using heat shrink to seal each
individual conductor. After the individual conductors are sealed, seal over the pair with
another layer of heat shrink.

Connection Tip: You may also use twist nuts specially designed for outdoor applications.
These twist nuts have a silicone core inside the nut head and coat the connection once
attached. These special nuts are not included but are widely available.

Troubleshooting

Loudness Button

Unnatural Sounds

Swapping Speaker 

Locations

If you hear obvious distortion from the speakers,
immediately lower the volume level of your receiver. Those
sounds often indicate that either the receiver or the speaker
is being over driven, and damage can result in playing your
source material (music-CDs-DVD-MP3) at high volume
levels for prolonged periods of time. You should also avoid
turning the bass or treble controls fully up and using your
"Loudness button" when the volume level is at or above
normal listening levels.

The Loudness button on most receivers is designed to add
depth when your system is being used for background
music or at very low volume.

Distorted or unnatural sound can indicate poor connections,
defective electronics, damaged source material or speaker
failure. If only one of your speakers has poor sound quality,
check the speaker wire and audio connections.

That doesn’t fix the problem? Try putting each speaker in
place of one another (swapping). If the sound remains poor
on the suspect speaker after swapping location and the
distortion moves with the speaker to the new location, the
speaker may be the problem. If the distortion remains in
the original location then the problem is elsewhere in your
audio system or speaker wiring. You must have proof of
purchase to receive warranty service.
