PLACING THE SUBWOOFER

The performance of a subwoofer is directly related to its placement in the listening room
and its physical position relative to the other speakers in the system.

While it is true that in general our ears do not hear directional sounds at the low
frequencies where subwoofers operate, when installing a subwoofer within the limited
conﬁnes of a room, the reﬂections, standing waves and absorptions generated within the
room will strongly inﬂuence the performance of any subwoofer system. As a result, the
speciﬁc location of the subwoofer in the room does become important to the amount
and quality of bass that is produced.

For example, placing the subwoofer next to a wall generally will increase the amount of
bass in the room; placing it in a corner

(1)

generally will maximize amount of bass in the

room. However, corner placement can also increase the destructive effect of standing
waves on bass performance. This effect can vary depending on the listening position –
some listening positions may yield very good results while others may have far too much
(or too little) bass at certain frequencies.

In many rooms, placing the subwoofer along the same plane as the left and right
speakers

(2)

can produce the best integration between the sound of the subwoofer and

that of the left and right speakers. In some rooms, the best performance could even
result from placing the subwoofer behind the listening position

(3)

We strongly recommend that you experiment with placement before choosing a ﬁnal
location for your subwoofer. One way you can determine the best location for the
subwoofer is by temporarily placing it in the listening position and playing music with
strong bass content. Move around to various locations in the room while the system is
playing (putting your ears where the subwoofer would be placed), and listen until you ﬁnd
the location where the bass performance is best. Place the subwoofer in that location.

NOTE: This subwoofer / LFE cable is not included, but
can be purchased from an electronics retailer.

• Be sure to turn the Crossover on the subwoofer fully

clockwise when using this type of connection. This type
of setting bypasses the subwoofer's internal crossover
and uses your receiver or processor's crossover.

• Check your receiver or processor menu settings and set

the subwoofer selection to 'On' or 'Yes.'

Please be sure to review the owner's manual for your
receiver or processor for more information on speaker
setup and configuration.

RCA Y-Adapter cable can also be used to make this type
of connection.

• We recommend setting the subwoofer's Crossover

setting to 80Hz for mid-sized speakers, higher for
smaller (satellite) speakers, and lower for larger
floorstanding speakers.
