Depending on lighting conditions, the enclosures may look different, but this does not indicate damage. *1 Before attaching the grille frame, confirm its correct mounting orientation. When attaching, press above the pin to firmly secure it. If the grille frame is protruding outward (it will not come off), push it all the way in. Attaching the grille frames is recommended even when not using the speakers in order to protect them from damage. The speakers can be enjoyed with the grille frames attached, but superior performance can be achieved by removing the grille frames. When removing the grille frame, take care not to bend or distort its shape excessively. Do not place the subwoofer in the following locations:  In places subject to high temperature or direct sunlight  In places subject to excessive dust and dirt  In places subject to high humidity  Near source components (CD players, record players, etc.)  Use caution when placing the subwoofer on a specially treated (waxed, oiled, polished, etc.) floor, as staining or discoloration may result.  Near magnetic cards (credit cards, commuter passes, etc.) Magnetic cards may fail due to the magnets in the woofer units.  Near televisions The subwoofer is not magnetically shielded. Therefore, if you use the subwoofer near CRT-based televisions, color shading occurs on the TV screen. If color shading occurs, turn off the TV, then turn it on again after 15 or 30 minutes. If the color shading persists, increase the distance between the subwoofer and TV. Setting the speakers Since the human ear cannot detect the direction and position where the bass sound being reproduced by a subwoofer (below 200 Hz) comes from, you can install the subwoofer wherever you like in your room. To obtain better bass reproduction, install the subwoofer on a solid floor where resonance will not occur. You can obtain sufficient heavy bass reproduction from a single subwoofer. However, using multiple subwoofers will yield more effective bass reproduction. Notes  Install the subwoofer vertically, 30 cm (12 in) away from walls.  Do not place any object on the subwoofer or sit on it.  Install the subwoofer near your front speaker.  For safety, install the subwoofer on a flat and firm floor.  If the subwoofer is installed in the center of a room, the bass may be extremely weakened. Move the subwoofer away from the center of the room or install it near a bookshelf, etc.  Take care to avoid any possible injury on the corners of the subwoofer.  Do not place bound or folded cords which are connected to your TV/ other video devices behind the subwoofer. Video noise may occur. 2GB
