17. If an outside antenna or cable system is
connected to the product, be sure the
antenna or cable system is grounded so as
to provide some protection against voltage
surges and built-up static charges. Article
810 of the National Electrical Code, ANSI/
NFPA 70, provides information with regard to
proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an
antenna discharge unit, size of grounding
conductors, location of antenna-discharge
unit, connection to grounding electrodes,
and requirements for the grounding
electrode. See Figure A.

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
with its satellite speakers. Setting the volume of the subwoofer 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
low will negate the benefits of the subwoofer.

result in an overpowering, boomy bass. Settingthe 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). Be sure to leave a
minimum of six inches between the wall and the port on the
subwoofer.
