FEATURES
• This subwoofer system employs Advanced Yamaha
Active Servo Technology II, which Yamaha has
developed for the production of higher quality, super-
bass sound. (Refer to page 7 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 easily be 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 power switch to turn the power on
and off.
• The subwoofer can be linked to a Yamaha component for
simultaneous power on/off operation.
Use the supplied system control cable to connect the
subwoofer to a Yamaha component that features a
system connector jack. When you turn on or off the
power to the connected component, the subwoofer will
also be turned on or off.
• You can select a bass effect suitable for the source by
using the B.A.S.S. switch.
• 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.

Since the low-end frequencies of audio signals feature long wavelengths, they are almost non-directional to human ears.
The super-bass range does not create a stereo image. Therefore, a single subwoofer may be enough to produce a high-
quality super-bass sound. However, using two subwoofers (similarly to L and R front speakers) can enhance your acoustic
experience.
Notes
• This unit features a magnetically shielded design. However, there is still a chance that placing it too close to a CRT-type TV set
might impair picture color. Should this happen, move this unit away from the TV set.
• If the speaker volume is very loud, furniture or window glass may resonate and the subwoofer itself may vibrate. In this case,
lower the volume level. To limit resonance, use a thick curtain or similar cloth that tends to absorb sound vibrations effectively.
Also, changing the subwoofer position may be helpful.
