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 front speaker. (See
A
fig. .) If using two subwoofers, it is recommended to
place them on the outside of each front speaker. (See
fig. B .) The placement shown in fig.
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.
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.
