an equilateral triangle, is intended to alert the
user to the presence of uninsulated “dangerous
voltage” within the product’s enclosure that may
be of sufficient magnitude to constitute a risk of electric shock
to persons.
The exclamation point within an equilateral
triangle is intended to alert the user to the
presence of important operating and mainte-
nance (servicing) instructions in the literature
accompanying the product.

Unpacking the Subwoofer

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 call your dealer or
distributor 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 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 wave-
lengths 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 recom-
mend 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).
Figure 1. This example shows the subwoofer positioned behind
the right-channel satellite speaker to re-create the actual location
of bass instruments in an orchestra and/or add impact to movie
soundtracks.
