Connecting Your Speakers-Continued Center Speaker Base Use the center speaker base to mount the center speaker horizontally. If you place the speaker and its base on top of a TV or an entertainment center, adjust the angle of the speaker so that it faces toward the listening position. The center speaker should be installed on the base securely. If the speaker is loose, try adjusting the position so that it sits securely on the base. The cradle surface of the base features two stoppers to prevent the speaker from moving. Therefore, you can tilt the speaker toward the front by up to 11 degrees. SKC-750C 11 Wall Mounting The speakers can easily be wall mounted by using the keyhole slots. To prevent the speaker from vibrating against the wall, attach four of the supplied rubber spacers to the rear of each speaker. ■ Mounting vertically To mount the speakers vertically, use the one keyhole slot shown to hang each speaker on the screw that is securely screwed into the wall. Rubber spacer Base for horizontal mounting Stoppers ■ Using the included rubber spacers We recommend using the supplied rubber spacers to achieve the best possible sound from your speakers. The rubber spacers prevent the speakers from moving, providing a more stable setup.

Caution: A mounting screw's ability to support a speaker depends on how well it's anchored to the wall. If you have hollow walls, screw each mounting screw into a stud. If there are no studs, or the walls are solid, use suitable wall anchors. Use screws with a head diameter of 3/8" or less and a shank diameter of 1/8" or less. With hollow walls, use a cable/pipe detector to check for any power cables or water pipes before making any holes. Leave a gap of between 1/4" Wall and 5/16" between the wall and the base of the screw head, as shown. (We recommend that you con- sult a home installation professional.) 1/4" - 5/16"
