The Yamaha KS-SW100 is a compact subwoofer for keyboard instruments that incorporates a variety of advanced, high-performance bass technologies including a Twisted Flare Port and Advanced YST II (Yamaha Active Servo Technology II), resulting in a clear bass response. The 100W amplifier drives the 8" woofer, which outputs a frequency response of 28 to 200 Hz. The Yamaha KS-SW100 ships with a 1/4" to RCA cable.

Compared to conventional ports, the Twisted Flare Port is engineered for a greater reduction of air turbulence noise, contributing to clear and accurate low-frequency reproduction. The flared and gently twisted shape evenly diffuses the airflow through the port.

Developed by Yamaha, the Advanced YST II (Yamaha Active Servo Technology II) combines negative-impedance and constant-current principles to drive the speaker cone for tighter control than the previous version. Using advanced negative impedance converter (ANIC) circuits, this system dynamically optimizes effective speaker impedance to maintain linearity. This contributes to a stable and accurate low-range response as well as high 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 theater.

A: The Yamaha NS-SW100 is not made for compatibility with the Yamaha P515 piano.

Q: 2. Can this be used with HS80M monitors? I've noticed that this subwoofer has a very different frequency response curve to the now discontinued HS10W subwoofer that was designed for the HS80M monitors.

A: Contacted Yamaha and they assure me that it can be used with HS80M monitors. Frequency response is different as the HS8S can go as low as 22hz (HS10W was 30hz). You just need to adjust the cross over frequency until it best complements the HS80M monitors.
