NS-SW200 is an active subwoofer of the Advanced Yamaha Active Servo Technology II (Advanced YST) series. This technology combines an amplifier and a speaker in one cycle, which allows you to transmit the most undistorted signal directly to the sounding element. The new shape of the Twisted Flare Port horn provides a clear sound of low overtones in the range from 28 to 200 Hz.
The built-in 250W amplifier is highly efficient, while consuming minimal energy and generating minimal heat. Due to the absence of an output filter coil, an exceptionally low level of noise and distortion is achieved. The transient characteristics are also excellent. The double feedback circuit (OS) reduces distortion by applying OS twice, resulting in cleaner sound.
The device is equipped with a 20-centimeter bass speaker located on the front panel. It is loaded onto a phase inverter port with a proprietary Twisted Flare Port profile, which significantly reduces airflow turbulence and, as a result, noise.
