Therefore, bass output is maximized when the subwoofer is placed in a corner. · It is also recommended that the subwoofer be positioned along the same wall as the front loudspeakers. Low-frequency sounds are normally omnidirectional, meaning the listener can't tell where they are generated from. However, frequencies between 75Hz ­ 150Hz can be localized, especially at higher volume levels. Positioning your subwoofer as recommended will provide the most natural soundstage and imaging from your loudspeaker system. Remember that these are just guidelines. Since every listening room is different, JBL strongly recommends experimenting with the positioning of your subwoofer to obtain the most pleasing results in your room. One technique that can help you find the ideal subwoofer location is to temporarily place the subwoofer near the main listening location. Then move around the room and determine where you hear the most pleasing bass performance. This would then be the ideal location for the subwoofer. SPEAKER CONNECTION When we designed the S120PII powered subwoofer, our goal was to offer the user the best possible performance combined with the most flexible and complete installation options. Please look over the following three examples to determine which description best matches your system and follow the corresponding hookup instructions. To use the binding-post speaker terminals ·ª with bare wire, unscrew the collar until the pass-through hole in the center post is visible under the collar. [. . . ] The Phase Control ¡ determines whether the subwoofer's piston-like action moves in and out in phase with the main speakers or opposite the main speakers. There is no correct or incorrect setting. Proper phase adjustment depends on several variables such as Remember, every system, room and listener is different. There are no right or wrong settings; this switch ¡ offers the added flexibility to adjust your subwoofer for optimum performance for your specific listening conditions without having to move your speakers.
