Placement, Hookup, Corner, Positioned along

Placement

• As a general rule, bass

response increases as a

subwoofer is placed closer

to a wall. 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

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

Remember that these are just guidelines. Since every listen- ing room is different, JBL strongly recommends experi- menting 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 tem- porarily place the subwoofer near the main listening loca- tion. 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.

Please look over the following four examples to determine which description best matches your system and follow the corresponding hookup instructions.

The “Direct” connection on the subwoofer is an output that allows you to connect

more than one subwoofer to your system for increased bass output. When hooking up the next subwoofer in the system, simply use the “Direct” output the same way you would connect a single (mono) subwoofer output from your receiver/amplifier.
