The Yamaha NS SW300 Active Subwoofer has a sleek and stylish design with a black ash finish that will complement any home theatre setup. Because of its small size, it can easily be integrated into your audio setup, even in small rooms, without taking up too much space.


The Yamaha NS SW300 Active Subwoofer is incredibly versatile, in addition to its advanced engineering and sleek design. Its line and speaker level inputs make it simple to connect to a wide range of audio systems, and its adjustable crossover frequency and phase controls give you complete control over the subwoofer's performance.

Create and construct
The Yamaha NS SW300 Active Subwoofer has a sleek and compact design that measures slightly more than 16 inches in height and width. Its elegant black finish and circular shape fit in with any home theatre setup. A downward-firing 10 inch cone driver delivers powerful, punchy bass from the subwoofer. It also has volume, crossover frequency, and phase controls, allowing you to fine-tune the bass output to your liking. The subwoofer has an integrated amplifier, which eliminates the need for an external power source and simplifies setup. 

The Yamaha NS SW300 Active Subwoofer produces powerful, distortion-free bass. The subwoofer can handle even the most demanding audio, with a 12" woofer and a high-current 250W amplifier, providing deep and punchy bass that adds impact to music and movie soundtracks. The advanced Yamaha design ensures precise and accurate sound reproduction, while the rigid, reinforced MDF construction reduces



unwanted resonances for clear and accurate sound. The frequency response of the NS SW300 is adjustable, allowing you to fine-tune it to your room and system, and the phase switch aids in the integration of the subwoofer with your main speakers for seamless, cohesive sound. The Yamaha NS SW300 Active Subwoofer will enhance your audio experience and bring your entertainment to life, whether you're watching movies, listening to music, or playing video games.

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.

PWM Digital Drive High Efficiency Amplifier and Dual Feedback Circuit

The built-in power amplifier delivers stable power output of 250 W 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 Awesome Deep Bass

Developed by Yamaha, the Advanced YST II (Yamaha Active Servo Technology 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 (ANIC) circuits, this system dynamically optimizes effective speaker impedance to maintain excellent linearity. This means more stable and accurate low range response, not to mention higher sound quality.

25 cm (10”) Cone Woofer Unit with Square Wire

A 25 cm (10”) large woofer unit is used in a front-firing configuration. The voice coil of the driver unit employs square wire with a wide surface area that can be wound more densely to obtain higher magnetic flux density. It delivers high drive force, permitting tight and deep bass reproduction.

Beautiful Design that Will Match a Wide Range of Speakers and Interiors

In addition to the beautifully round shape of the front surface, panels on both sides to create an accent, and a neat appearance, this subwoofer lets you imagine the strength of sound and matches a wide range of speaker systems. Numerous color variations are provided, so you can select one matched to your interior.



The Yamaha NS SW300 Active Subwoofer is a high-quality, versatile, and stylish subwoofer that produces powerful, punchy, and deep bass. Its design and construction are sturdy, and it is simple to integrate into a variety of home theatre setups. Whether you want to enhance your music listening or create an immersive movie experience, the Yamaha NS SW300 Active Subwoofer is a great choice for delivering the deep, tight bass you need to complete your sound experience.

I admit that I was initially wary,
But my experience ended up being
fantastic. I spent less for a Denon
250bt than was offered during
the festive sales on Amazon and
Flipkart, even with the card discount.
I received my delivery in under two

My wife and I planned to put audio
systems for music in our living room
bedroom, and kitchen. Additionally,
we desired home theatre installation.
We found the members of the avfive
team to be educated, truthful, and
straightforward while working with
them. We purchased a bookshelf
speaker, ceiling speakers, and Denon
6500 AV receiver from AVfive. When
we had questions, they also followed
up and assisted with troubleshooting
Working with AVfive is something I'd
strongly advise.

Provided original goods (B&O Play A6) at a price that was competitive with other websites. Additionally, good customer service throughout delivery and installation I'm so grateful to them.
