Yamaha NS-SW300-BL 10″ Subwoofer, Black (SG Warranty)

A design combining superior operability and beauty. And introducing a new technology, Twisted Flare Port, for clear and tight bass. A subwoofer that will match a wide range of speakers and interiors. 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. Available in black color.
