Positioning possibilities
Moving the subwoofer closer to walls
and corners in particular will generally
increase the amount of bass. Although
the extra amount of bass can be
compensated for by reducing the volume
level of the subwoofer relative to the
rest of the system, this can result in
uneven bass response at the listening
position. You can try starting with
placement in a corner and experiment
by gradually moving it out of the corner
or further away from the wall. Try to
locate the position which yields the best
compromise between position, volume
and even bass response. Note that every
time that you reposition the subwoofer
(even if it’s over a short distance) you
may need to adjust the level and phase
settings again.
Corner placement
This placement yields maximum boost
of bass level but potentially uneven
distribution of bass in the room (room-
modes), particularly if the room is square
or shoe-box shaped.
From the listening position, check
if the bass is even across the entire
bass spectrum. If not, move the
subwoofer out of the corner. Try
moving it along either wall.
Next to wall, away from corner
This position still provides considerable
boost but less than the corner placement
as above. Room-modes can also still be
considerable but less so than with corner
placement.
From the listening position, check
if the bass is even across the entire
bass spectrum. If not, move the
subwoofer away or towards your
listening position until the most even
response has been obtained.
Avoid placing the subwoofer exactly
half-way or at a quarter of the wall’s
length.
Free standing, away from wall and
corner
This position will give least boost
compared to wall or corner placement,
but in general offers the best exibility at
achieving most even bass distribution at
the listening position.
Avoid placing the subwoofer exactly
half-way or at a quarter’s length of
either sidewall.
Particularly in smaller square or
“shoe-box” shaped rooms the free
standing position is recommended.
