LU43P-LU53P 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 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.
