LU43P-LU53P INTRODUCTION
Introduction
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 or
temporary outdoor use. Both models are available in black
or white.
For simplicity, we will call your AV receiver or amplifier
the “receiver.”
Important
Warranty Coverage
For Your Records
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.
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.

LU43P-LU53P PLACEMENT
Speaker Placement
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).

LU43P-LU53P INSTALLATION
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.

LU43P-LU53P CONNECTION
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.
LU53P
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.
LU43P
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.

LU43P-LU53P CONNECTION & TROUBLESHOOTING
Connecting Speakers
Your Speakers
The speaker wire must be securely connected 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.
It is recommended that the wire insulation be stripped back
approximately 3/8”, allowing the wire conductor to make a
proper connection. Make sure that the wire insulation is
stripped back far enough so that the bare speaker wire will
make a proper connection to the metal clip inside the
terminal and be securely held in place. This can be
confirmed visually.
Distortion/Knocking
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 eleswhere in your audio/video system.
