INSTALLATION/OWNER’S MANUAL
Indoor/Outdoor 3-Way Dynamic Loudspeakers
Introduction
The DUAL outdoor speaker series is designed as a multipurpose speaker and will
deliver accurate high fidelity sound in exterior or interior environments.
Weather-resistant design and construction provide optimum durability for
permanent ortemporary outdoor use. Both models are available in black or
white.
For simplicity, we will call your AV receiver or amplifier the “receiver.”
Important
The grilles are not designed or intended to be removed. Do not remove the
grilles from your speakers. There are no userserviceable parts behind the
grille and removal will damage the speaker.
Warranty Coverage
You must have proof of purchase to receive warranty service.
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.

Mounting Placement
If mounting is desired, mounting both speakers on a common solid surface
facing the listening area will provide the best audio results.
Do NOT mount speakers on wall surfaces that have hazards concealed behind
them, such as electrical wires or plumbing. Always mount speaker on surfaces
that are sturdy enough to support the speakers’ weight, and make sure they
cannot fall or cause injury.
Speaker Placement
Your speakers can be placed in many convenient locations in your home or
patio area – as stereo pairs on either side of your receiver – as surround
speakers in home theater surround sound systems – in your computer room to
enhance the multimedia experience – or as remote speakers.
Wall and Ceiling Placement
For wall and ceiling applications, DUAL mounting brackets are included. In
addition, the LU43 has a rear inset keyhole for surface hanging, and the
larger LU53 has two 1/4-20 brass inserts incorporated into the rear of the
enclosure if aftermarket mounting systems will be used.
Experiment for Better Sound
You should experiment with various placements. Room acoustics can produce
large apparent differences in the sound when small changes in the placement
are employed.
For example, although the speaker may be located at any height above the
floor, directing the tweeter toward ear level (32″ – 36″) or angling the
entire speaker toward the listening position often provides the most realistic
imaging experience. The amount of bass perceived increases as you move a
speaker closer to solid intersecting room surfaces (walls, ceiling,
floor).
Placement & Mounting Speakers
Outdoor Placement
The DUAL LU43 and LU53 have been tested for environmental usage and are
weather resistant, but not waterproof. Occasional moisture will not affect
performance.
The speakers should be allowed to ventilate and dry after water exposure.
The speakers can be placed permanently outdoors for yearround enjoyment.
To maximize speaker life, position in areas protected from the elements, such
as the underside of eaves and overhangs.
Popular locations include decks, gazebos, porches, atriums, garages, and
covered spa areas.
For temporary placement, remove the speaker from the mounting brackets and
replace the thumb screws to maintain stability if placing the speakers on end.
Both the LU43 and LU53 speakers have a DUAL logo that can be rotated. The logo
is located on the face of the grille in the event a vertical installation is
needed. The logo is spring loaded. Use gentle force when adjusting the logo to
a new orientation. To rotate the logo, elevate two ends of the logo equally
by placing your nail under and lifting lightly. While the logo is elevated,
turn the logo to the desired orientation and release.
Mounting Your Speakers
For ease of installation, the DUAL LU43 and LU53 include an easily removable
mounting bracket. Once mounted, the bracket allows the speaker to be pivoted
to its ideal location.
The included thumb screws knobs will hold the selected speaker position when
properly tightened. Avoid over tightening the knob. Before attempting the
installation, carefully evaluate the mounting surface, making sure that its
composition and construction are strong enough to support the load safely. If
you are unsure about the type of mounting hardware for your installation,
consult a professional contractor or a knowledgeable hardware store. The
anchors and screws to attach the speakers are not included and must be
purchased separately. The hardened steel brackets are suitable only for
attaching the speaker to walls or ceilings constructed of solid wood,
brickwork, concrete, hollow buildings block or wood studs.
Do not mount the bracket to non-reinforced plaster sheetrock (gypsum board).
Once the bracket is secure, reattach the speaker using the thumb screws
included.
Connecting Speakers
Connecting Your Speakers
Speaker Wire -Typical speaker wire has a pair of separate speaker wires with
insulating jackets that are molded together. Dual recommends the use of two
conductor 18gauge speaker wire to connect your speakers to your receiver.
Measure enough wire to reach from your receiver to each speaker plus
additional length to allow moving the speakers or receiver without having to
disconnect the wires.
When connecting the speakers in a stereo configuration, the wire length should
be similar. One length should not be dramatically longer or shorter then the
other.
Maintaining similar wire lengths will provide superior sound quality.
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 colortype or colors of the wires/wire itself (copper or
silver).
Important – Always connect speaker wire using the positive (+) terminal on the
receiver to the positive (+) terminal, and the negative (-) terminal on the
receiver to the negative (-) terminal. All speakers in a system must be
connected with the same respective polarity. The speaker inputs are located
on the rear-mounted terminal cup on the back of the speaker.
Terminal Type – The LU43 utilizes a push-pin design. Gently depress the
colored lever and insert the stiped end of the wire directly into the opening
located in the center of the input housing. – The LU53 uses a screw type input
post. To loosen, turn the gold terminal counter clockwise, insert the wire
end and re-tighten. The gold terminal have Red (POS) and Black (NEG) polarity
indicators.
STEP 1
Unscrew the caps covering each binding post until you expose the small hole
through their centers.
These caps are typically colored red and black, and represent positive and
negative terminals, respectively.
STEP 2
Twist the bare speaker wire to create a single strand.
STEP 3
Insert each side into the exposed holes.
STEP 4
Tighten the cap to secure the wire in place.
The speaker wires must be securely inserted into the connector and tightened
properly to the speaker inputs. Do not over-tighten. Do not allow the positive
and negative speaker wire from the receiver to make contact, as this will
cause a short.
Banana style connectors may also be used on the LU53. The connection is made
by connecting the speaker wire to the banana plugs, and then inserting the
banana plug into the top portion of the binding posts.
Troubleshooting
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 overdriven, 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.
Note: 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.
If 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/video system
