 Product Features

The Yamaha NS SW300 Active Subwoofer is a high-quality, powerful subwoofer designed for home theatre and music applications. It is an excellent addition to any home audio setup thanks to its advanced engineering and sleek design.

The advanced engineering of the Yamaha NS SW300 Active Subwoofer includes a large, powerful 12 inch cone driver, a high-quality Class-D amplifier, and a BASS (Bass Active Servo System) that ensures precise, distortion-free bass response.

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. 

Performance
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
