Crossing the
border between HiFi and theatre sound reproduction, deep, tight bass
brings out the individuality of the main speaker system. Yamahas new
subwoofer proudly brings you 1kW of output power. High strength, heavy enclosure with twisted flare port1kW digital power amplifier using the latest digital devices and a huge analogue power supplyAll-new 30cm (12) subwoofer combining a double magnet and a Kevlar composite coneHigh-class external design with a choice of normal or piano finish
The NS-SW1000 is a new Yamaha high-end subwoofer faithfully utilising
Advanced YST ll (Yamaha Active Servo Technology ll) polished over the
span of a quarter century to achieve highly musical reproduction of
exceedingly low bass frequencies. The main themes in developing this
model were completely achieving both high sound quality and high output
power and both HiFi and theatre reproduction. While maintaining the
huge power output and sound levels of the previous YST-SW1500, the
NS-SW1000 aims to deliver uncompromisingly delicate musical expression
that brings out the individuality of the main speaker. For that reason,
maximum priority was given to creating an extremely efficient speaker
within which to employ the unique A-YSTII technology. The foundation for
this is the massive 19kg (41.9 lbs) high strength, heavy enclosure
around the 30cm (12) woofer unit with double magnets, the all-new
Yamaha digital amplifier IC, and the high 1kW output power amplifier
incorporating a large analogue power supply. These three elements fuse
an extraordinary scale with traditional musicality to bring you deep,
tight, authentic bass thats perfect for watching movies, listening to
multi-channel audio or music videos, or for bringing dramatic richness
to high-end audio systems.
High Strength, Heavy Enclosure Structure Using Traditional three-way mitered-joint constructionThe cabinet employs a massive 19kg (41.9 lbs) high strength, heavy
bass reflex enclosure constructed of thick 36mm (1-3/8) MDF
(medium-density fiberboard) on the baffle sides and 25mm (1) MDF on the
other sides with traditional three-way mitered-joint construction. It
has a strong resonance-resisting structure with cast-iron legs and a
front-firing design with the woofer unit attached to the front of the
enclosure. It delivers direct, razor-sharp sound thats ideal for
high-end audio systems.
New Twisted Flare Port Produces Clear and Tight BassThe all-new Twisted Flare Port takes advantage of extensive subwoofer
development experience. 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.
From special effect sounds in movies to the atmosphere of a live venue,
you hear bass that is clear, tight and realistic.
Digital Power Amplifier Achieves 1kW Output Power with a High Current MOS-FET Discrete Output StageThe 1kW output power digital amplifier employs a drive stage using
the all-new Yamaha digital amplifier IC and a high current MOS-FET
discrete push-pull output stage. Careful sound quality tuning included
the use of a luxurious triple-wound Litz wire high-capacity output coil
and capacitors especially designed for audio, resulting in optimum high
quality and high power, for use in theater or HiFi environments.
Huge Analogue Power Supply with High Capacity Output Transformer and Large Block Electrolytic CapacitorsThe huge power supply for the built-in power amplifier has a massive
10.2kg (22.5 lbs) high capacity power transformer and two large 160V
4,700F block electrolytic capacitors, making it capable of sustaining
the 1kW power output. Yamaha used a conventional pure analog power
supply to achieve superior response and musicality in the very low bass
Convenient Size, Majestic Bass Reproduction. Yamahas Unique A-YSTII TechnologyEnlarge
Developed by Yamaha, the Advanced YST II (Yamaha Active Servo
Technology II) combines negative-impedance and constant-current
principles to drive the speaker cone with even tighter control than the
previous version. Using Advanced Negative Impedance Converter (ANIC)
circuits, this system dynamically optimises effective speaker impedance
to maintain excellent linearity. This means more stable and accurate low
range response, not to mention higher sound quality.
All-New 30cm (12) Woofer Unit with Double Magnet and Double DamperTo achieve long-stroke drive with its superior linearity, the
NS-SW1000 uses a 30cm (12)woofer unit with a strong, flexible drive
system employing double layer large diameter ferrite magnets and a
double damper with an air vent. The frame is high strength aluminium
diecast to suppress unwanted resonance even at high volumes, making it
possible to reproduce delicate tonal nuances.
Optimally Designed Semi-Pressed Paper Cone with Kevlar FibersThe specially designed woofer diaphragm is semi-pressed paper
incorporating Kevlar fibers for high strength and optimal internal
losses. It was developed for this model in pursuit of the ideal
characteristics for a subwoofer.
Choice of Three Cabinet Finishes Including Piano Finish
The NS-SW1000 cabinet exterior is available in your choice of black
piano, white piano, or black embossed laminate. The piano finish uses
the same material as Yamaha grand pianos, and in the last production
step each unit is carefully polished, giving a good gloss for your
livingroom or listening room. The embossed laminate is ideal for home
theatre with a subdued gloss that reduces reflection onto your viewing
screen and a scratch resistance surface. High-Grade Cabinet Design Anticipates Use with High-End HiFi Equipment
The aluminium front panel with its hairline finish gives an accent to
the front panel, and the large aluminium volume control knob, power
switch and other controls are spread over the front panel to make a
high-grade, comfortable design that is a good match for high-end HiFi
Subwoofer. Auto Standby
If a no-signal condition persists for more than 8 minutes, the system
power turns off and a standby condition is entered. Recent
energy-saving technology keeps power consumption in standby mode to
under 0.3W. System Control
A System Control connector is provided, and by connecting it to the
System Control connector on a Yamaha AV amplifier or integrated
amplifier, the power can be set to be automatically turned on and off
with the connected amplifier. A 5m (16 ft) cable is provided. Phase SwitchoverOn the rear panel a phase switchover selector is provided that
selects either normal or reverse woofer output phase. You can set the
best phase according to your listening environment while doing
comparative listening tests.
B. A. S. S. mode
By using the rear panel B. A. S. S. switch, you can set the units tonal
characteristics to Music or Movie. Choose the optimum setting depending
on the programme source or equipment configuration.
