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 fig.
Å .) If using two subwoofers, it is recommended to place
them on the outside of each main speaker. (See fig. ı .) The
placement shown in fig. Ç 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.
Å or ı .
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.
( : subwoofer, : main speaker)
Use the nonskid pads
Put the provided nonskid pads at the four corners on the
bottom of the subwoofer to prevent the subwoofer from
moving by vibrations etc.
