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.
