SUBWOOFER PLACEMENT
RECOMMENDATIONS
For best performance, follow these recommendations when placing the subwoofer:
• Do NOT place any objects on top of the subwoofer.
• To avoid wireless interference, keep other wireless equipment 1 – 3 ft (0.3 – 0.9 m)
away from the subwoofer. Place the subwoofer outside of and away from metal
cabinets, other audio/video components, and direct heat sources.
• Place the subwoofer on its rubber feet on a stable, flat, and level surface. For proper
support, its feet must be resting flat on the surface. Vibration can cause the
subwoofer to move, particularly on smooth surfaces like marble, glass, or highly
polished wood.
• Place the subwoofer along the same wall as your TV, or along any other wall in the
front third of the room.
• Keep the front side of the subwoofer (the side opposite the F connector) at
least 3 in (7.6 cm) from any other surface. Blocking the port on the boom of this
side may aect acoustic performance.
• For more bass, place the subwoofer closer to walls and corners. For less bass, place
the subwoofer further from walls and corners.
• Make sure there is an AC (mains) power outlet nearby.
CAUTION: Do NOT place the subwoofer on its side or top when in use.
