Kawai GL20 WH

Kawai GL-20 white acoustic grand piano

Kawai GL-20 is a compact acoustic grand piano at 157 cm in length, combining a fuller tonal volume than expected from its small cabinet with a responsive mechanical action. Compared to the GL-10, its slightly longer string scale and larger resonance area provide additional depth to the bass register.

GL Series: Kawai grand piano technology in a compact size

The GL series brings the natural mechanics of a grand piano to homes, music schools, studios, and small performance venues in a more versatile size. Because the string scale, soundboard, and cabinet volume of each model are tailored to its dimensions, the GL-20 creates its own unique bass depth, projection, and resonance duration within the series.

Millennium III Action

The Millennium III grand piano action uses ABS-Carbon components reinforced with carbon fiber. These lightweight and rigid parts contribute to faster key movement transmission to the hammer, clear articulation of repeated notes, and stable control across various dynamics. Extended keys provide a more even response at both the front and rear of the playing surface.

Solid spruce soundboard

The soundboard, crafted from straight-grained, quarter-sawn solid spruce, is tapered to create optimal flexibility in every zone. This construction transforms string energy into a warm, clear, and balanced tone. Hammers with premium underfelt support a natural balance between the fundamental tone and harmonic richness. Front and rear duplex scaling add brilliance and harmonic color in the high register.

Solid construction and tuning stability

The SOLID — Stretcher Over-Lap Integrated Design system creates a stable foundation for string tension by firmly integrating the pinblock and the upper beam into the cabinet. The cast-iron frame, manufactured using the V‑Pro vacuum mold method, precisely bears the high tension.
