Introduction
Features
• This subwoofer system employs Advanced
Yamaha Active Servo Technology II which
Yamaha has developed for reproducing higher
quality super-bass sound. (Refer to page 5 for
details on Advanced Yamaha Active Servo Tech-
nology II) This super bass sound adds a more
realistic, theater-in-the-home effect to your ste-
reo system.
• This subwoofer system is equipped with a linear
port unique to Yamaha that provides smooth
bass response during playback, minimizing
extraneous noise not included in the original
input signal.
Positioning the subwoofer
It is recommended to place it on the outside of
either the right or the left front speaker. (See fig.
.) The placement shown in fig.

possible, however, if the subwoofer system is
placed directly facing the wall, the bass effect may
lessen 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.
