PLACEMENT

Since the installation of a subwoofer can be somewhat more
complicated than installing full-range speakers, it is essential
that you read this section very carefully prior to connecting the
subwoofer to your system. Should you have questions relating to
your installation, it is advisable to contact either your dealer or
distributor, or visit www.jbl.com, for advice.

The performance of the subwoofer is directly related to its
placement in the listening room and how you align the subwoofer

ith its satellite speakers. Setting the volume of the subwoofer

w
in relation to the left and right speakers is also of critical importance
because it is essential that the subwoofer integrate smoothly with the
entire system. Setting the subwoofer’s volume level too high will
result in an overpowering, boomy bass. Settingthe volume level too

ow will negate the benefits of the subwoofer.

l
Here are several additional facts on installation that may prove

seful. It is generally believed by most audio authorities that low

u
frequencies (below 125Hz) are nondirectional and, therefore,
placement of a subwoofer within any listening room is not critical.
While in theory it is true that the larger wavelengths of extremely
low frequencies are basically nondirectional, the fact is that,

hen installing a subwoofer within the limited confines of a room,

w
reflections, standing waves and absorptions generated within the
room will strongly influence the performance of any subwoofer
system. As a result, specific location of the subwoofer becomes
important, and we strongly recommend that you experiment with
placement before choosing a final location.

Placement will depend upon your room and the amount and quality
of bass required (for example, whether or not your room permits
placement of the subwoofer near either satellite). Be sure to leave a
minimum of six inches between the wall and the port on the subwoofer.

Figure 1. This example shows the subwoofer positioned in the
corner to maximize bass output.
