POSITIONING THE SUBWOOFER
Fig. 8
• Generally, avoid placing the subwoofer at ¼, ½ or ¾ of
either the length or width of the room as at these
locations the room-modes are likely to be strongest (the
dashed lines in fig. 8)
Fig. 9
Corner placement
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.
Fig. 10
Next to the wall - away from the 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
most even response has been obtained.
Avoid placing the subwoofer exactly half-way or at a
quarter of the wall's length (refer to fig. 8).
Free standing, away from wall and corner
Fig. 11
This position will give least boost compared to wall or cor-
ner placement, but in general offers best flexibility at
achieving most even bass distribution at the listening posi-
tion.
Avoid placing the subwoofer exactly half-way or at a quar-
ter's length of either sidewall (refer to fig. 8).
Particularly in smaller square or "shoe-box" shaped rooms
the free standing position is recommended.
