PLACEMENT

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 main speaker (see
A). If using two subwoofers, it is recommended to place
them on the outside of each main speaker (see B). The
placement shown in C 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 A or B.
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.
