Positioning the subwoofer
( : subwoofer, : front speaker)
One subwoofer will have a good effect on your
audio system, however, the use of two subwoofers
is recommended to obtain more effect.
If using one subwoofer, it is recommended to place
it on the outside of either the right or the left front
speaker. (See fig.
.) If using two subwoofers, it is
recommended to place them on the outside of each
front speaker. (See fig.
.) The placement shown
in fig. is also possible, however, if the subwoofer
system is placed directly facing the wall, the bass
effect may die because the sound from it and the
sound reflected by the wall may cancel out each
other. To prevent this from happening, face the
subwoofer system at an angle as in fig.
or .
Note
There may be a case that you cannot obtain enough
super-bass sounds from the subwoofer when
listening in the center of the room. This is because
“standing waves” have been developed between two
parallel walls and they cancel the bass sounds.
In such a case, face the subwoofer obliquely to the
wall. It also may be necessary to break up the parallel
surfaces by placing bookshelves etc. along the walls.
Use the non-skid pads
Put the provided non-skid pads at the four corners
on the bottom of the subwoofer to prevent the
subwoofer from moving by vibrations etc.
