NS-SW100 Subwoofer This subwoofer incorporates a number of Yamaha's advanced features and high performance bass technologies such as Twisted Flare Port and Advanced YST II (Yamaha Active Servo Technology II) with discrete amp circuitry and high quality (10") woofer unit. This results in sensational bass response that adds significantly to overall listening enjoyment of music and movies. Features New Twisted Flare Port for clear and tight bass Advanced YST II 10" cone woofer Frequency response: 25Hz - 180Hz Dimensions (W x H x D): 13 7/8" x 13 7/8" x 16 1/8" Clear Tight Bass 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 effects sounds in movies to the atmosphere of a live venue you hear bass that is clear tight and realistic. Advanced YST II 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.
