The Yamaha KS-SW100 subwoofer incorporates a range of advanced, high-performance technologies, including the Twisted-Flare port and Advanced YST II (Yamaha Active Servo Technology II).
The Twisted-Flare-Port draws on extensive experience in subwoofer development. The flared, slightly twisted shape disperses the air vortex generated around the edge of the speaker, thereby ensuring a uniform airflow. This reduces extraneous noise that is not present in the original input signal and delivers clear, precise low-frequency reproduction.
Developed by Yamaha, Advanced YST II (Yamaha Active Servo Technology II) combines the negative impedance and constant current principles to drive the speaker cone with even greater control than the previous version. The use of advanced negative impedance converter circuits (ANIC) dynamically optimises this system
The KS-SW100 is compatible with, amongst others, the following keyboards: PSR-EW410 / PSR-S670 / PSR-SX600 / PSR-SX700 / PSR-SX900 / PSR-A3000 / as well as older PSR-S models.
