UNPACKING THE SUBWOOFER

If you suspect damage from transit, report it immediately to your

dealer. Keep the shipping carton and packing materials for future

use.

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 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).

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 sound-

tracks.

INSTALLING SPIKED FEET

Four metal spikes are supplied for use when the speaker is to be

placed on a carpeted surface; using them decouples the speaker

from the floor to prevent unwanted damping. To insert the spikes,

gently lay the speaker on its side (not its front or back) on a soft,

nonabrasive surface, and unscrew the rubber-tipped feet (store in a

safe place). Each spike then screws into the threaded insert in each

corner. Make sure all four spikes are screwed in completely for sta-

bility. To protect the surface of uncarpeted floors, set each spike into

an included metal coaster.

NEVER drag the speaker to move it, as this will damage the spikes,

the feet, the wood cabinet itself, and/or the floor. Always lift the

speaker and carry it to its new location.
