Sunfire True Subwoofer Super Junior - Manual (Page 10)

User's Manual 10
Your Sunfire Subwoofer is designed to
be placed in a corner and this will
produce optimum performance.
Experiment with at least two corners and
then decide which is the best.
#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 woofer 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.
Although low frequencies are non-
directional, factors such as room
reflections, standing waves, resonance
and absorption strongly affect your
subwoofer’s performance.
Moving the subwoofer from one corner
to another can have a major effect on the
bass response.
Remember to keep it 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
fields upsetting the TV screen or erasing
your magnetic media.
Also position the control panel so that
it is not touching anything and can
receive good ventilation.
Location
Using Two Subwoofers
If you wish to use two woofers, the
sound output will double (an increase of
6 dB). Locate the woofers with one in
each corner and experiment with the
location and phase control to achieve the
best bass response.
Always drive each woofer through the
Left/Mon input even though you are
driving one woofer with a right channel
drive and the other with a left channel
drive. If your preamplifier has a single
sub/LFE output, use a Y cable to split it
into two outputs.
