Kawai US-6X – 52” Professional Grand Upright
The Kawai US-6X is widely considered one of the finest upright pianos ever produced by Kawai. Standing at 52” tall, this "Grand Upright" was designed to provide the tonal depth, projection, and string length of a baby grand piano while maintaining a space-saving vertical profile. Part of the prestigious US-series, the US-6X features a massive soundboard and a specialized music desk, making it a favorite among advanced players and professionals.
Built in Japan during what many consider the "golden era" of Kawai manufacturing, the US-6X is distinguished by its large grand-style music rack and premium internal components. It delivers a thunderous bass, a lush midrange, and a singing treble, all powered by Kawai’s ultra-responsive action. Finished in a high-gloss Ebony Polish, its commanding presence is matched only by its incredible musicality.
