LUR66E
INSTALLATION/OWNER'S MANUAL
2-Way Outdoor Rock Speaker
LUR66E INTRODUCTION
Welcome
Congratulations on your purchase of the LUR66E rock speaker. A high level of design
experience and engineering went into its creation. With the rugged look of weathered
sandstone, the LUR66E 2-way rock speaker is 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.
The LUR66E's weather resistant design is made possible by using the most durable
components including a fiber-reinforced poly resin composite enclosure. This allows it
to resist rain, hail, sleet, coastal environments and snow, but still appear natural and
inconspicuous. You will find that the materials used in the LUR66E are also superior in
resisting sun fade and water marks. It was specifically designed to look and sound great
for seasons to come.
Important
Although the LUR66E speaker is designed to resist weather and withstand unfriendly
environmental conditions, there are precautions you should take to optimize the
long-term life and performance. Keep soil, debris and wood chips 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 speaker components.

LUR66E INSTALLATION
Sound Coverage and Speaker Placement
The LUR66E is sold separately, as many outdoor installations have multiple zones. It is
assumed for the purpose of this manual that the rock speaker will be installed using a
minimum of two speakers. When deciding on the placement, allow for a total coverage
area of approximately 100 to 450 sq.ft. per pair of rock speakers. This estimate is 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 this in mind when planning the wire run to each speaker location.
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 attempt to remove the
grilles from your rock speaker. There are no user serviceable parts behind the grille and
removal will damage the speaker.

LUR66E CONNECTION
Connections
The LUR66E rock speaker has a two-conductor speaker wire surrounded by a cable
sleeve exiting the bottom of the speaker. Any speaker cable used to extend the
connection should be of a similar size (wire gauge) running from the speaker location to
your audio system.
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 enclosure 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' for the
most favorable results. Runs longer then 50' are possible, but may require larger gauge
wire. It is recommended to use 14 or 12 gauge for speaker wire runs longer then 50'.
Ask your Dual dealer or consult a professional contractor if you have questions regarding
long wire runs.
Parallel or series wiring is commonly acceptable for the LUR66E rock speaker to gain
correct amplifier loading. For best results, avoid series wiring The LUR66E speaker with
any other speaker type or brand.
The LUR66E speaker wires are marked for polarity for determining the positive and
negative identity of the individual wires within the molded pair insulation. Polarity is
shown by either a color or 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 on the speaker, and the
negative (-) terminal on the receiver to the negative (-) wire on the speaker.
For a typical audio installation, all speakers in a system will be connected with the same
respective polarity. 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.

LUR66E TROUBLESHOOTING
Distortion
Using Loudness
Unnatural Sounds
Swapping Speaker
Locations
For Your Records
If you hear obvious distortion from the speakers,
immediately lower the volume level of your receiver.
Distortion often indicates the speaker is being over driven,
and damage can result by playing at high volume levels for
prolonged periods of time.
The Loudness function on most receivers is designed to
enhance the bass and treble (for background music or
listening at low volume levels).
Distorted or unnatural sound can indicate poor connections,
defective electronics, poorly recorded 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.
Please keep your original sales receipt and be prepared to
provide this receipt in the event you require service, as your
original receipt is considered the best proof of purchase and
indicates the date you purchased your Dual product.
