Yamaha NS-SW300 Video Review:

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 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.

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 airflow 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, 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.
