Yamaha NS-SW300 subwoofer combines superior operability and beauty. Besides it offers a new Twisted Flare Port technology for clear and tight bass. This model fits perfectly into every interior and its performance will not disappoint your even in larger rooms. Its built-in BASS switch (Bass Action Selector System) enables you to switch between Music and Movie modes and then controls the subwoofer to deliver optimal performance. Subwoofer consumption reaches only 0.3W in the standby mode.

Key Features

  • Highly efficient digital amplifier with dual PWM feedback circuit.
  • New twisted flare port for a clear and tight bass.
  • The Advanced YST II (Yamaha Active Servo Technology II)
  • 25cm (10") speaker with square wire voice coil
  • Elegant design that perfectly fits into many interiors
  • Control panel with the volume and switch-on button on the front
  • Auto Standby switch / Sensitivity selector (high, low and off)
  • 3 inputs (speaker terminals, L/R RCA, LFE), a phase control (normal, reverse).


New twisted flare port

The all-new Twisted Flare Port takes advantage of extensive subwoofer development experience. Its flared, gently twisted 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 you with 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.

PWM digital amplifier with dual feedback circuit

The built-in power amplifier delivers stable power output of 250W with high efficiency while minimizing power consumption and heat production. It does not require an output filter coil, resulting in extremely low noise and distortion. High speed transient response is also excellent. The dual feedback circuit reduces distortion by applying feedback twice, resulting in higher sound clarity.

Advanced YST II for amazing deep bass

Developed by Yamaha, the Advanced YST 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 circuits, this system dynamically optimizes effective speaker impedance to maintain excellent linearity. You can expect more stable and accurate low range response as well as higher sound quality.
