Experience powerful bass impact from music and movies with the NS-SW300 10" 250W Powered Subwoofer from Yamaha. This dynamic subwoofer features a front-firing 10" cone woofer and is powered by a capable 250W amplifier. With a frequency response of 20 - 160 Hz, this subwoofer is designed to handle a wide variety of listening material. Advanced YST II technology is onboard for enhanced sonic accuracy.

The Yamaha NS-SW300 offers multiple connection options including direct LFE and line-level inputs. The rear-mounted system control interface allows you to connect the subwoofer to compatible amplifiers for automatic power on and off; a system control cable is included. As an added convenience, this subwoofer features front panel controls, which allow you to easily adjust the subwoofer's volume level, as well as a power button and LED indicator.

PWM Digital Drive High Efficiency Amplifier and Dual Feedback Circuit

The built-in power amplifier is engineered to deliver a 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 reduced noise and distortion. High speed transient response is also enhanced. The dual feedback circuit reduces distortion by applying feedback twice, resulting in optimal sound clarity.

10" Cone Woofer Unit with Square Wire

A 10" woofer unit is used in a frontfiring 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.

Twisted Flare Port

Compared to conventional ports, the Twisted Flare Port is engineered for a greater reduction of air turbulence noise, contributing to clear and accurate low frequency reproduction. The flared and gently twisted shape evenly diffuses the air flow through the port.

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 for tighter control than the previous version. Using advanced negative impedance converter (ANIC) circuits, this system dynamically optimizes effective speaker impedance to maintain linearity. This contributes to a stable and accurate low range response as well as high sound quality.

Auto Power Standby

If no signal is input from the amplifier for a fixed period of time, the subwoofer automatically switches to a standby state. When a signal from the amplifier is detected, power turns on automatically. This is designed to limit energy consumption.

Cabinet Design

The subwoofer features a round shape on the front surface and panels on both sides. These accents are designed to give the subwoofer a neat appearance.

Other Features

• Low standby power consumption of 0.3 W
• Auto power standby switch (high, low, and off)
• Phase control (normal or reverse)
• High-cut adjustment knob
• B.A.S.S. (Bass Action Selector System) switch
