A Bass Reinforcement Designed for Keyboard Playing
The Yamaha KS-SW100 is an essential keyboard accessory if you want to add more depth and realism to your sound without changing your keyboard. Relying on your instrument's built-in speakers, this subwoofer immediately supports electric piano, organ, synth sounds, and especially accompaniment styles by making bass lines more present and rhythms more impactful. The result: a more inspiring touch, a more "live" playing feel, and a more balanced sound at moderate volume, perfect for home practice, rehearsals, or a small home studio space. It is especially recommended for Yamaha PSR-EW400, PSR-S670, PSR-S700, PSR-S710, PSR-S750, PSR-S770, PSR-S900, PSR-S910, PSR-S950, PSR-S970, and PSR-A3000 models.
