Twisted Flare Port
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.
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.
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.
TWISTED FLARE PORT
Today’s bass reflex speakers use a Helmholtz
resonator to improve their bass reproduction.
However when reproducing bass that is in the
frequency region of this Helmholtz
resonator, air moves violently in and out
through the port between the interior and
exterior of the speaker, sometimes producing
noise due to the turbulent air flow at the end
of the port.
The port and the cabinet resonate at a
frequency that is determined by their
dimensions and shape. On the other hand,
turbulence in the air flow at the end of the port contains a broad range of frequency
components that are not present in the input signal. This noise occurs because the broad
range of frequency components includes components that match the resonant frequencies
of the port and cabinet, causing strong resonance.
The Twisted Flare Port developed by Yamaha changes the way in which the port widens
toward its end, and also adds a “twist” to suppress airflow turbulence at each end of the port
and thus prevent noise from occurring.
This substantially reduces the “muddy sound” and “wind noise” that until now have been
characteristic of bass reflex speakers, allowing bass to be reproduced clearly.

NOTE
The placement shown in the figure below is also possible.
However, if the subwoofer system is placed directly facing a wall,
the bass effect may suffer due to phase cancellation caused by
the interference between the direct and reflected sounds.
To prevent this from happening, place the
subwoofer system at an angle.
(Figures , , and )
ABC
There may be a case that you
cannot obtain enough super-bass
sound from the subwoofer due to
standing waves.
• This subwoofer system employs Advanced Yamaha
Active Servo Technology II, which Yamaha has
developed for the production of higher quality, superbass sound. 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 STANDBY/ON button 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.
• The flared, gently twisting shape diffuses the vortex of
air generated around the edge of the port, creating a
smooth flow of air. This reduces extraneous noise not
present in the original input signal, and provides clear,
accurate low frequency reproduction.
• The subwoofer can also reproduce a bass sound that is
appropriate for the source. (NS-SW300 only)
It features a B.A.S.S. switch that enables you to select a
bass effect that is suitable for the source.
SUPPLIED ACCESSORY
After unpacking, check
that the following
accessory is contained.
PLACEMENT
English
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 highquality super-bass sound. However, using two subwoofers (similarly to L and R front speakers) can enhance your acoustic
experience.
Subwoofer orientation
Place the subwoofer as shown in fig. , or for the optimum effect. : subwoofer : front speaker
Using one subwoofer
Place the subwoofer on the outside of either the left or right
front speaker.
Using two subwoofers
Place them on the outside of
each front speaker.
Placing the subwoofer in between the left and
right front speakers
If you are placing the subwoofer in between the left and
right front speakers, position it slightly at an angle toward
the wall for better effect.
NOTE
• 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.
