L83BK INTRODUCTION
Introduction
The DUAL outdoor speaker series is designed as a multi-
purpose 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.”
The grilles are not designed or intended to be removed. Do
not remove the grilles from your speakers. There are no
user-serviceable 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.

L83BK PLACEMENT
Speaker 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.
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.
For wall and ceiling applications, DUAL mounting brackets
are included. In addition, the L83BK has a rear inset
keyhole for surface hanging if aftermarket mounting
systems will be used.
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).

L83BK INSTALLATION
Placement & Mounting Speakers
The DUAL L83BK speakers 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 year-
round 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.
The L83BK 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.
For ease of installation, the DUAL L83BK includes 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

L83BK CONNECTION
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
18-gauge 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 L83BK 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.

L83BK CONNECTION & TROUBLESHOOTING LU83BK SPECIFICATIONS
Connecting 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.
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.
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.
