12" Square Wound Voice Coil / 1000 Watt / Advanced YST II (Black)
Hear what couldn’t be heard. See what couldn’t be seen
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 that’s 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 construction
The 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 that’s ideal for high-end audio systems.
New Twisted Flare Port Produces Clear and Tight Bass
The 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 Stage
The 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 Capacitors ,The 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 4,700μF 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 range.
