New Twisted Flare Port Produces Clear and Tight Bass

Yamaha's NS-SW300 subwoofer utilises the same 'twisted flare port' design as it's sibling, the NS-SW200 - this port shape is said to diffuse the vortex of air generated around edge port of the speaker to create a smoother flow of air. This then makes a reduction of unwanted noise that isn't found in the original input signal, and therefore provides accurate, deep bass frequencyt reproduction. Whether that be special effect sounds from films or the thick atmosphere of a live venue performance. 

PWM Digital Drive High Efficiency Amplifier and Dual Feedback Circuit

The NS-SW300 has an amplifier built in to it that delivers a stable power output of about 250 W, with high effiency while consuming as less power as possible. It doesn't require an output filter coil, which results in phenomenally low noise and disortion. The double feedback circuit system causes reduction in distortion by applying feedback twice, this results in a higher sound quality and better detail

Advanced YST II for Awesome Deep Bass

Yamaha's own developed Advanced YST II (Yamaha Active Servo Technology II) creates a combination of negative-impedance and constant-current principles to drive the speaker cone with an even tighter amount of control that the previous version of this subwoofer. Also, using ANIC circuits, this system sonically optimizes effective speaker impedance to maintin excellent linearity.

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.
