YAMAHA NS-SW300

Yamaha NS-SW300 Active Subwoofer – 10” 250W Hi-Fi & Home Theater Subwoofer

The Yamaha NS-SW300 is a high-performance active subwoofer designed to deliver deep, powerful and precise bass for Hi-Fi stereo systems and home theater setups. Equipped with a 25 cm (10-inch) cone driver and a high-efficiency 250 W built-in amplifier, this subwoofer produces rich low frequencies that enhance both music and movie soundtracks.

Thanks to Yamaha’s proprietary Advanced YST II (Yamaha Active Servo Technology), the amplifier and driver work together to achieve excellent control and linearity, delivering powerful bass with minimal distortion. The innovative Twisted Flare Port reduces air turbulence inside the bass reflex port, producing tighter and clearer low-frequency response.

The PWM digital drive amplifier with dual feedback circuit ensures stable power output with low noise and high efficiency, while the B.A.S.S. (Bass Action Selector System) allows users to optimize bass performance depending on the content, such as music or movies. :contentReference[oaicite:1]{index=1}

It is an ideal addition to bookshelf or floorstanding speaker systems to extend the low-frequency range and create a more immersive listening experience.
