Kawai GX-1 Acoustic grand piano

Kawai GX-1 professional acoustic grand piano

Kawai GX-1 presents the professional materials and mechanical precision of the GX series within a versatile 166 cm body. Despite its compact size, it creates clear articulation, balanced resonance, and controlled dynamics.

Ryuyo craftsmanship and the character of the GX series

The GX series combines Kawai's tradition of grand piano manufacturing in Ryuyo, Japan, with modern material engineering. The tonal goal of the series is to provide natural transitions between registers, wide dynamics, clear projection, and reliable mechanical control for the pianist. With a string scale and soundboard adapted to its size, the GX-1 demonstrates these features with unique sound volume and resonance duration.

Millennium III Grand Piano Action

The Millennium III action uses ABS-Carbon components reinforced with carbon fiber. Because this material is lighter and stiffer than wooden action components, it facilitates rapid note repetition, precise pianissimo control, and stable response during powerful performance. Extended keys create more even resistance from the front to the back of the keyboard, while NEOTEX white and black key surfaces provide a controlled touch during long playing sessions.

Mahogany hammers and tonal precision

The GX series uses lightweight and stiff mahogany-core hammers with full underfelt. The mass and hardness of the hammer transmit energy from the key to the string precisely, creating a clear response from soft nuances to powerful climaxes. Front and rear duplex scaling utilize the harmonic energy in the non-speaking parts of the strings, adding brightness and extra color to the sound in the upper register.

Solid spruce soundboard and resonance system

The 1.17 m² solid spruce soundboard, featuring straight grain and tapered processing, converts string vibrations into a broad, balanced tone. 3 back posts, a vertically laminated treble bridge, and a hybrid inner frame support the transfer of energy to the soundboard. The CORE system unites the piano's main power points at the acoustic center; the SOLID construction holds the pinblock, upper cross-block, and case in a single robust structure. The V‑Pro vacuum-molded iron plate is engineered for stability under high string tension.
