LU50PB/LU50PW INTRODUCTION
Introduction
The DUAL LU50PB and LU50PW are multi-purpose
speakers manufactured and designed to deliver accurate
high fidelity sound in exterior and interior environments.
The weather-resistant design and construction make the
DUAL LU50’s ideal for permanent or temporary outdoor use.
The versatile mounting options makes the LU50PB/PW
equally at home anywhere.
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.

LU50PB/LU50PW PLACEMENT
Indoor/Outdoor Placement
The DUAL LU50PB/PW can be placed in any convenient
location in your home or patio area - as stereo pairs on
either side of your receiver - as surround speakers in home
theater surround sound systems that include a subwoofer -
in your computer room to enhance the multimedia
experience - or as remote speakers.
For ease of installation in wall and ceiling applications, the
DUAL mounting brackets (included) can be used. You should
experiment with various placements. Room acoustics can
produce large apparent differences in the sound for small
changes in the placement location. For example, although
the speaker may be located at any height above the floor,
locating the tweeter near ear level (32" –36" is optimum) or
angling the entire speaker toward ear level, often provides
the most realistic imaging experience. The amount of bass
perceived increases as you move a speaker closer to
intersecting room surfaces (walls, ceiling, floor) and the
highest level of bass results are realized from placement in
a corner at the floor or ceiling.
The DUAL LU50 has been tested for environmental usage
and is weather resistant, but not water proof. Occasional
moisture will not dramatically affect performance.To
increase speaker life, mount in locations not subject to
frequent excessive exposure to water, sun and extreme
weather. the speakers should be allowed to ventilate and
dry after water exposure. The DUAL LU50 can be placed
permanently outdoors for year-round enjoyment. Popular
locations include decks, gazebos, porches, atriums,
garages, and covered spa areas. A particularly practical
mounting location is under the eaves of a building adjacent
to an outdoor recreation area.
For temporary placement, remove the mounting brackets
and knobs to maintain stability and place the speakers on
end or on the side, in positions that achieve the most
satisfying audio performance to your ear.

LU50PB/LU50PW INSTALLATION
Mounting & Connecting Spea ers
For ease of installation, the DUAL LU50 includes an easily
removable mounting bracket with each speaker. Once
mounted, the bracket allows the DUAL LU50 to be pivoted to
its ideal location. The thumb screws knobs (included), when
tightened properly , will hold the selected speaker position.
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 LU50
are not included and must be purchased separately. The
LU50PB/PW bracket is 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 or
sheetrock (gypsum board). Once the bracket is secure,
reattach the speaker using the thumb screws included.
Spea er Cable -Typical speaker cable has a pair of separate
speaker wires with insulating jackets that are molded
together. We recommend you use 18-gauge speaker wire
for hooking your speakers to your receiver.
Polarity - All speakers in a system must be connected with
the same polarity. Speaker wire is marked for polarity so
that you can identify the individual wires in the molded pair.
Polarity is shown by a color stripe on the insulation, by
ridges molded into the insulation, or by the colors of the
wires–one copper and one silver.
Important - Always connect the red (+) terminal on the
receiver to the red (+) terminal on the back of the DUAL
LU50, and the black (-) terminal on the receiver to the black
(-) terminal on the back of the DUAL LU50.

Troubleshooting

LU50PB/LU50PW TROUBLESHOOTING
If you believe you hear obvious distortion or knocking
sounds, 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-CD’s-DVD) at high
volumes. You should avoid turning the bass or treble
controls fully up or using your "Loudness button" when the
volume level also is turned up. This can lead to costly
loudspeaker failure.
Distorted or unnatural sound can indicate poor connections
or a speaker failure. If only one of your speakers has poor
sound quality, check the connections. If that doesn’t fix the
problem, try putting each speaker in place of one another .
If the sound remains poor on the suspect speaker and the
distortion moves to the new position, the speaker has a
problem. If the sound is OK, it is probably the receiver or the
speaker wiring that is causing the poor sound at the original
location.
