FEATURES
• This subwoofer system employs Advanced Yamaha
Active Servo Technology II, which Yamaha has
developed for the production of higher quality, superbass sound. (Refer to page 14 for details on Advanced
Yamaha Active Servo Technology II.) This super-bass
sound adds a more realistic, theater-in-the-home effect
to your stereo system.
• This subwoofer can be easily added to your existing
audio system by connecting to either the speaker
terminals or the line output (pin jack) terminals of the
amplifier.
• For effective use of the subwoofer, the subwoofer’s
super-bass sound should be matched to the sounds of
your front speakers. You can create the best sound
quality for various listening conditions by using the
HIGH CUT control and the PHASE switch.
• The Automatic power-switching function saves you the
trouble of pressing the STANDBY/ON button to turn the
power on and off.
• You can select a bass effect suitable for the source by
using the B.A.S.S. button.
• 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.
QD-Bass Technology
QD-Bass (Quatre Dispersion Bass) technology is a
Yamaha unique technology to radiate the sound
efficiently in four horizontal directions.

SUPPLIED ACCESSORIES
After unpacking, check that the following parts are
contained.
Non-skid pads
ATTACHING THE NONSKID PADS
To enjoy the high sound quality, stabilize the subwoofer
using the non-skid pads.
Attach the provided non-skid pads in the four corners of the
underside of the subwoofer to prevent the subwoofer from
moving as a result of vibration, etc.
PLACEMENT
One subwoofer will have a good effect on your audio
system, however, the use of two subwoofers is
recommended to obtain more effect.
A
If using one subwoofer, it is recommended to place it on
the outside of either the right or the left front speaker. (See
fig. A .) 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. C is also possible,
however, if the subwoofer system is placed directly facing
the wall, the bass effect may suffer due to cancellation of
direct and reflected sounds. To prevent this from
happening, place the subwoofer system at an angle, as in
fig. A or B .
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 developed between two parallel walls and
cancel the bass sounds.
In such a case, place the subwoofer at an oblique angle
to the wall. It also may be necessary to break up the
parallel surfaces by placing bookshelves, etc. along the
walls.

8
Select “MOVIE” or “MUSIC” according to the played
source.
MOVIE:
When a movie type source is played, the lowfrequency effects are enhanced to allow listeners to
enjoy more powerful sound. (The sound will be richer
and deeper.)
MUSIC:
When an ordinary music source is played, the
excessive low-frequency components are cut off to
make the sound clearer. (The sound will be lighter to
reproduce the melody line more clearly.)
Notes
• Once the volume balance between the subwoofer and
the front speakers is adjusted, you can adjust the
volume of your entire sound system by using the
amplifier’s volume control.
However, if you change the front speakers to others,
you must make this adjustment again.

ADVANCED YAMAHA ACTIVE SERVO TECHNOLOGY II
In 1988, Yamaha brought to the marketplace speaker
systems utilizing YST (Yamaha Active Servo Technology)
to give powerful, high quality bass reproduction. This
technique uses a direct connection between the amplifier
and speaker, allowing accurate signal transmission and
precise speaker control.
Yamaha’s newly developed Advanced YST II adds many
refinements to Yamaha Active Servo Technology,
allowing better control of the forces driving the amplifier
and speaker. From the amplifier’s point of view, the
speaker impedance changes depending on the sound
frequency. Yamaha developed a new circuit design
combining negative-impedance and constant-current
drives, which provides a more stable performance and
clear bass reproduction, without any murkiness.
As this technology uses speaker units controlled by the
negative impedance drive of the amplifier and resonance
generated between the speaker cabinet volume and port, it
creates more resonant energy (the “air woofer” concept)
than the standard bass reflex method. This allows for bass
reproduction from much smaller cabinets than was
previously possible.
