Your subwoofer is designed to be placed
in a corner and this will produce optimum
performance.
#1 is very good positioning.
#2 is also excellent but may shake
the back wall too much and cause
things on or along the wall to rattle
too much. If this occurs, use the #3
position:
#3 Move the subwoofer approximately
three feet away from the right wall
and place it along the back wall
as shown. This will substantially
reduce the rattling of the back wall
and will still pressurize the room
with lots of bass.
Experiment with at least two corners and
decide which is the best, or you can try
the following procedure:
1. Start by placing the subwoofer right
on the seat of your favorite couch
or easy chair. Take care to position
it so it is not likely to fall off. (This
method may seem a bit odd, but it
is based on principles of acoustic
physics.)
2. If you are using the subwoofer as
part of a Home Theater system,
you can either run a calibration
test (noise) signal through the
subwoofer, or simply plug the
analog outputs of a CD player di-
rectly into the subwoofer’s line-level
inputs. Turn down the subwoofer's
volume level before turning on the
CD, then play some of your favorite
music samples with heavy bass.
Location
3. Walk around the room, listening,
and stand in all the positions where
you might be able to place the
subwoofer. Try crouching down,
and try the corners. Find the place
where the subwoofer's bass output
sounds the loudest.
4. Shut things down and install the
subwoofer in this position. Make
sure the control panel is not touch-
ing anything, and that it can receive
good ventilation.
Although low frequencies are non-direc-
tional, factors such as room reections,
standing waves, resonance and absorp-
tion will strongly affect your subwoofer’s
performance. Moving the subwoofer from
one location to another can have a major
effect on the bass response.
The Auto EQ mode will let you adjust for
the room effects, but you should nd the
best location rst.
Remember to keep the subwoofer
at least two or three feet away from
any TV screen, computer, VCR or
magnetic tapes and discs. This will
reduce the chance of the magnetic elds
upsetting the TV screen or erasing your
magnetic media.
Using Two Subwoofers
If you wish to use two subwoofers, the
sound output will double (an increase of
3 dB). Locate the subwoofers with one
in each corner and experiment with the
location and phase control to achieve the
best bass response.
Use the Slave input and output con-
nections if you are using two ATMOS
subwoofers.
