NS-SW500
Sound to fire the imagination
The high-performance A-YST II subwoofer, with response to 20Hz - sound to stir the soul
Yamaha's proprietary A-YST II (Advanced Yamaha Active Servo Technology II) delivers big-speaker bass from a compact cabinet. It's the reality and richness of real bass - bass you can feel as well as hear.
The unique port design strictly controls airflow during bass reproduction. This minimizes annoying "breathing" sounds and further enhances the sensation of speed and clarity provided by the A-YST II system. The result is high-quality bass, well delineated and without even a trace of muddiness.
The subwoofer's 250-watt power amp makes full use of Yamaha's expertise in electronic circuit technology. Delivering bass that's both deep and tight while drawing just 80 watts of electric power, it fully meets today's needs for quality sound and lower energy consumption.
Yamaha's uncompromising dedication to sound quality finds expression in each and every part used in the NS-SW500, all carefully selected for optimal performance.
The subwoofer amplifier automatically switches into standby mode whenever it detects no input for an extended period. That means efficient energy use, even if you leave the power on.
The NS-SW500 is designed with the environment in mind. Power consumption in standby mode is only 0.3W, meeting the latest official European standards.
Connections include power supply linkage with the YSP series of digital sound projectors, making it easy to incorporate the NS-SW500 into your home theater system.
Advanced Yamaha Active Servo Technology (Advanced YST) is a unique system in which the speaker and amplifier work together to cancel out impedance so the speaker unit has a perfectly linear motion. Advanced YST helps to ensure the highest levels of sound pressure and overall performance.
QD-Bass (Quatre Dispersion Bass) technology uses down-firing drivers with square, pyramid-shaped reflective plates to radiate the sound efficiently in four horizontal directions. The reflective plates negate any effects caused by the floor surface and reduce resonance between sound waves reflected from the floor and the unit.
