PLACEMENT
Since the installation of a subwoofer can be somewhat more
complicated than installation of 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 the
JBL Customer Service Department for advice.
The ES150PW/ES250PW’s wireless capability makes it even easier to
properly locate the subwoofer in your room. The performance of the
subwoofer is directly related to its placement in the listening room
and how you align the subwoofer with its satellite speakers. Setting
the volume of the subwoofer in relationship 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 overpowering, boomy
bass. Setting the volume level too low will negate the benefits of the
subwoofer.
Here are several additional facts on installation that may prove
useful. It is generally believed by most audio authorities that low
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, when
installing a subwoofer within the limited confines of a room,
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).

right-channel satellite speaker to re-create the actual location of
bass instruments in an orchestra and/or add impact to movie sound-
tracks.
