Yamaha NS-SW100 Subwoofer Speaker with 100W Output Power and Twisted Flare Port, Black

This subwoofer incorporates a number of Yamaha's advanced and a 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 25 cm woofer unit. This results in a sensational bass response that adds significantly to overall listening enjoyment of music and movies. 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. 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. The gently rounded form with a slanted front surface presents a stylishly elegant appearance. Designed to be unobtrusive, It's sure to look beautiful in a living room or home theatre room. Offered in black, walnut and white, so you can choose the model that best matches your other speakers.
