[. . . ] MagnaGuard ® magnetic shielding ensures the speakers' magnetic field does not interfere with the television's picture, allowing placement next to a TV in a home theater system. How to Connect Your Speakers Correctly wiring your speakers is important for achieving the best sound quality. Wiring should take just a few minutes, but it's important to do it carefully, since incorrect wiring (such as reversed connections) can result in a poor soundstage and poor bass. We recommend 18-gauge wire or thicker for runs up to 25 feet (8m), and 16-gauge wire or thicker for longer runs. Separate the first few inches of the wire conductors. [. . . ] Separate the first few inches of the wire conductors. Strip off 1/2" (12mm) of insulation from the ends of each speaker wire to expose the two conductors and tightly twist the wire strands. When making all connections, be sure to connect the + (red) on the speaker to the + (red) on the amplifier, and the ­ (black) on the speaker to the ­ (black) on the amplifier. WARNING: To prevent electrical shock hazard, always switch off the amplifier or receiver when making connections to the speaker. IMPORTANT: Typically, one side of the wire is smooth. Connect this side to the ­ (black) connection. Connect this to the + (red) connection. Using the five-way binding posts: The binding posts permit easy connection to banana plugs, spade lugs, and bare wire. Insert the wire in the hole and tighten. 3 Connecting the Speakers to Your Amplifier or Receiver Basic Hookup 1. Connect the speaker terminals to the amplifier speaker outputs. Make sure the speaker terminal jumper straps are in place on the back of the speaker. (VR2 and VR3 only) IMPORTANT: When making all connections, be sure to connect + to + (red) and ­ to ­ (black). VR1/XS-L152P5 VRC VR2 or VR3 Speaker terminal jumper straps in place left front center front right front surround sound receiver or amplifier Bi-wiring (VR2, VR3 only) Bi-wiring increases the flow of current and decreases intermodulation of different frequencies by providing separate inputs to the woofer and midrange/tweeter sections. If your listening position happens to be less than the distance that the speakers are apart, then you may prefer to "toe-in" the speakers slightly. Place the VRC center channel speaker as shown below, with the front of the speaker flush with the front of the television. The VRC is specially tuned to sit atop of a large, flat TV screen. This is quite important, since the TV screen surface acts as a large baffle that can alter a speaker's sound, degrading both dialogue and music. Four self-adhesive rubber feet are provided to protect the TV's finish and prevent vibration.

If your room is square (same length and width), you may experience low frequency standing waves that can reduce overall clarity. Experiment with different placements and toe-in to avoid this. Also, the more fabric material there is in a room (curtains, sofas, carpets, etc), the more that high and midrange frequencies will be dampened. Conversely, the more exposed bare walls there are in the room, the brighter the speakers will sound. Thus, you may also want to experiment with speaker placements with these considerations in mind. 6 Using the Carpet Spikes For placing speakers on thick carpet, we recommend using the four threaded carpet spikes and lock nuts (VR2 and VR3 only) which serve three purposes -- leveling (an aesthetic issue), stability (a practical issue) and rigidity (an acoustic issue).

The spikes concentrate the speaker's weight on four points, creating focused pressure that anchors the speaker cabinet to the floor and enhances rigidity. For most carpeting, leaving about 1/2-inch (12mm) of the carpet spike exposed is sufficient, although this may be adjusted as necessary. [. . . ]
