YAMAHA NS-SW700 black


The NS-SW700 subwoofer can easily reproduce solid tones of fast attacks and deep tones with space rendering, even though the tones are seemingly the opposite. This model can easily handle any reproduction, so it will be great for music. However, the output is not just a listening experience, with the dazzling power of this subwoofer, you will also be able to feel the individual sound vibes. Its built-in Bass (Bass Action Selector System) switch lets you choose between Music and Movie modes and then controls the subwoofer in the right way. Of course, the top cut can also be set to perfectly match the output of the subwoofer to the range of the rest of the speakers used. The power consumption of this subwoofer in standby mode reaches just 0.5 W. It is also magnetically shielded to minimize interference with home electronics.

Key features

  • Highly efficient digital amplifier with PWM and double feedback.
  • Advanced YST II Technology (Yamaha Active Servo Technology II)
  • 25 cm (10") speaker with 300W amplifier.
  • Designed design that fits perfectly into many interiors.
  • Control panel with volume, power button, BASS button and upper cut at the top of the subwoofer.
  • Auto Standby / Auto Standby - Auto Standby (off, low, high).
  • 3 inputs (speaker terminals, L / R cinch, LFE) and phase switch (normal, reverse).


Digital amplifier with PWM and double feedback

Built-in amplifier delivers a steady output of 300W, all with high efficiency, with minimal power consumption and residual heat output. This system does not require an output filter coil, resulting in extremely low noise and distortion. Duplicate feedback reduces distortion twice, resulting in higher audio clarity.

Advanced YST II for amazing bass depth

Yamaha Active Servo Technology II combines negative impedance and constant current principles to control the speaker with even more precise control than the first version. Using advanced negative impedance converting circuits, effective speaker impedance is dynamically optimized to ensure excellent linearity. Thanks to this, you can look forward to a more stable and accurate response at low frequencies and overall better sound quality.

QD-Bass Technology

Quatre Dispersion Bass technology uses a downward-facing transducer with square, pyramid-shaped reflective plates to radiate the sound in four directions horizontally. The reflective plates neutralize all the floor surface responses while reducing the resonance between the sound waves reflected from the floor and the subwoofer.
