is needed to find the optimum placement.
The placement will affect the phase
difference between the main loudspeakers
and the subwoofer and the bass roll-off
rate.
First place the subwoofer slightly offset
from the center of the front wall. The
recommended distance to the wall is
less than 60 cm / 24" measured from the
subwoofer's driver. This position gives
increased acoustic loading (and SPL) due
to the proximity of the front wall and floor.
Cancellations from the front wall and floor
are also avoided. Front wall cancellation for
the 85 Hz high pass filtered main speakers
can be eliminated by placing them at least
110 cm / 43" away from the front wall (see
Figure 3).
If the frequency balance does not seem
right, try moving the subwoofer slightly
to the left or right so that different room
modes are excited at different levels.
Positioning the subwoofer close to a
corner will boost the bass level at lower
frequencies and may cause asymmetrical
spatial imaging.
Minimum Clearances To Walls
Or Other Objects
Do not cover the driver side of the subwoofer
or place the subwoofer so that there is less
than 10 cm (4") of free space in front of the
grille.
Make sure that the space underneath the
subwoofer is clear from obstructions. Thick
carpets may block the ventilation clearance
needed for cooling the electronics.
The reflex port side (opposite of the
connector panel side) should always have a
clearance of at least 7.5 centimeters (3") to
any objects to ensure proper functioning of
the reflex port.
Flush Mounting The
Subwoofer
If the subwoofer is flush mounted into a
wall or a cabinet, it is important to ensure

tions for a single subwoofer and also
work well with two linked subwoofers.
Position 3 causes a significant bass
boost and may cause asymmetric spa-

used. Position 4 also works best with
two subwoofers. Flush mounting (pos.
5) generally works well.
