The Yamaha KS-SW100 is a compact yet powerful 50-watt subwoofer designed specifically for keyboard instruments. It features advanced Yamaha bass technologies, like the Twisted Flare Port and Advanced YST II (Yamaha Active Servo Technology II). The Twisted Flare Port diffuses air vortices, reducing noise and delivering clear, tight, and realistic bass. Whether it's movie special effects or a live venue atmosphere, you'll enjoy accurate low-frequency reproduction. The Advanced YST II offers even tighter control over the speaker cone, optimizing impedance for stable and high-quality low-range response. With its stylishly elegant design - a gently rounded form with a slanted front surface - it's a great addition to any living room or home theater. Available in black, walnut, and white to match your decor. Technical specs include an 8-inch cone driver, 100W dynamic power, 50W output power, a frequency response of 28 - 200 Hz, and dimensions of 291 x 292 x 341 mm (11-1/2” x 11-1/2” x 13-3/8”), weighing 8.5 kg (18.7 lbs).
