FEATURES
• This subwoofer system employs Advanced YAMAHA Active
Servo Technology which YAMAHA has developed for
reproducing higher quality super-bass sound. (Refer to page
12 for details on Advanced YAMAHA Active Servo Technol-
ogy.) This super-bass sound adds a more realistic, theater-
in-the-home effect to your stereo system.
• This unit can be added easily to your existing audio system
by connecting to either the speaker terminals or the line
output (pin jack) terminals of the amplifier.
PLACEMENT
One subwoofer will have a good effect on your audio system,
however, the use of two subwoofers is recommended to obtain
more presence.
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. To prevent this, face the subwoofer system
obliquely to the wall as in fig.

or
ı
.
Note
There may be a case that you cannot obtain enough super-
bass sounds from this unit when listening at the middle of the
room. This is because “standing waves” have developed
between two parallel walls and the bass sounds are canceled.
In such a case, face the unit obliquely to the wall. It also may
be necessary to break up the parallel surfaces by placing
bookshelves etc. along the walls.
