Before Using the Home Theater Speaker Package Using the Rubber Stoppers for a More Stable Platform We recommend using the supplied rubber stoppers to achieve the best possible sound from your speakers. The rubber stoppers prevent the speakers from moving, providing a more stable platform. Rubber stoppers Bottom of the SKF-391/ SKR-391 Rubber stoppers Bottom of the SKC-391/SKC-391C 1" (25 mm) 1-3/16" (30 mm) Using the Floor Pads for Subwoofer If the subwoofer is placed on a hard floor (wood, vinyl, tile, etc.) and playback is very loud, the subwoofer's feet may damage the flooring. To prevent this, place the supplied pads underneath the subwoofer's feet. The pads also provide a stable base for the subwoofer. Pad Wall Mounting To mount the front/surround speakers vertically, use the keyhole slot shown to hang each speaker on a screw that's securely screwed into the wall. Keyhole slot for wall mounting SKF-391/SKR-391 To mount the center speaker horizontally, use the two keyhole slots shown to hang the speaker on two screws that are securely screwed into the wall. Keyhole slots for wall mounting SKC-391/ SKC-391C 6-5/16" (160 mm) Tip • If the center speaker is tilted, loosen the screw on the declined side to move upward so that the speaker could be adjusted vertically. Caution • A mounting screw's ability to support a Wall 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, 3/16" to 7/16" or the walls are solid, use suitable wall (5 to 10 mm) anchors. Use screws with a head diameter of 5/16" (9 mm) or less and a shank diameter of 1/8" (4 mm) 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 3/16" (5 mm) and 7/16" (10 mm) between the wall and the base of the screw head, as shown (We recommend that you consult a home installation professional).
