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.
