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

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.

Front Control Panel for Easy Operation

The power and volume buttons, which are used most often, are laid out on the front surface of the unit for ease of access. It is inclined at an angle of 45°, making it easy to use even when placed on the floor. An LED indicator is above the power button, so even in a dimly lit room it's easy to tell if it's on or off.

System Control and Auto Standby

The system control terminal can be linked to the amplifier power to automatically turn the power on and off. There is also an Auto Standby Function: If no signal is input from the amplifier for a fixed period, it automatically switches to the standby state, and when a signal from the amplifier is detected, power turns on automatically. This limits the wasteful consumption of electricity.

    Low standby power consumption of 0.3W
    Auto Standby switch / Sensitivity selector (high, low and off)
    Phase control (normal or reverse)
    B.A.S.S. switch

Laboratory test report



Newport Test Labs measured the frequency response of the Yamaha NS-SW300 subwoofer at a distance of two metres, using a pink noise stimulus. Figure 1 shows the resulting responses after they’d been smoothed via third-octave filtering. You can see that the LFE input of the SW300 bypasses the subwoofer’s inbuilt high-cut filter, so if you use the LFE input, you will need to do any filtering using your AV receiver’s crossover circuitry. You can see that for both the LFE input and the 140Hz setting of the Yamaha’s high-cut control, the NS-SW300’s output peaks at 90Hz, rolling off shallowly above this via the LFE input (black trace) and a little faster for the 140Hz setting (green trace). The overall frequency response for the 140Hz setting is about 45Hz to 180Hz ±3dB, which is an excellent result. The black trace shows the frequency response of the NS-SW300 when the high-cut is set to 40Hz, and with this setting of the control, the subwoofer’s frequency response was measured as 23Hz to 120Hz ±3dB. In this setting, the subwoofer’s output peaks at around 50Hz. Perhaps more importantly, the frequency response is very linear at this setting, extending from 30Hz to 80Hz ±1.2dB. Overall, the Yamaha NS-SW300 shows exemplary performance for a subwoofer of its size.
