Kawai GL-40 acoustic grand piano

GL Series: Kawai grand piano technology in a compact size

The GL Series provides the natural action of a grand piano in more flexible sizes for homes, music schools, studios, and small performance venues. Since each model's string scale, soundboard, and cabinet volume are built to suit its dimensions, the GL-40 creates unique bass depth, projection, and resonance within the series.

Millennium III Action

The Millennium III grand piano action utilizes ABS-Carbon components reinforced with carbon fiber. These lightweight and rigid parts contribute to the rapid transmission of key movement to the hammer, clear repetition of notes, and stable control across various dynamics. The extended key length provides a more uniform response from the front to the back 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 structure converts string energy into a warm, clear, and balanced tone. Fully under-felted hammers support a natural balance between fundamental sound and harmonic richness. The front and rear duplex scaling add extra brilliance and harmonic color in the upper register.

Sturdy construction and tuning stability

The SOLID (Stretcher Over-Lap Integrated Design) system integrates the pinblock and stretcher bar firmly into the cabinet, creating a stable foundation for string tension. The iron frame, produced via the V-Pro vacuum casting method, precisely carries high tension. The CORE system is designed to increase tonal power and sustain by aligning the power centers of the frame, inner rim, and back posts within the piano's acoustic core.
