Extended Length Keys Made by Spruce

Spruce is the ideal material for the keys – light, yet extremely strong for its weight. It responds with minimal flex and exceptional consistency, transmitting every subtle nuance of the pianist’s performance while remaining stable through years of heavy use. The length of each key has been extended to make playing easier and provide more even response from the front to the back of the playing surface. Keysticks are also designed with a slightly taller profile for maximum rigidity to deliver greater power.

NEOTEX key surface

Our exclusive NEOTEX key surface material made of cellulose fiber offers the smooth, understated texture of natural ivory and ebony – and a semi-porous, silica-filled surface to absorb the hand’s natural oils and perspiration. Since NEOTEX is used for both the sharps and naturals, the feel of the keys is consistent across the entire keyboard. NEOTEX resists cracking and fading over years of use and is static-resistant to help prevent the build-up of unwanted dust. The result is a beautiful, long-lasting key surface with exceptional playability.

CORE System

CORE is an acronym that represents “Convergence for Optimum Reflected Energy.” Convergence refers to the way the piano’s strength centers—the rim, plate and underside beams—all focus on one central point at the heart of the instrument. This focus creates an incredibly strong “core” foundation that maximizes the reflective capabilities of the inner rim for outstanding tonal power and sustain.

Hybrid Inner Rim (Konsei Katagi Rim)

The exclusive Konsei Katagi rim uses a blend of distinctive hardwoods to achieve an ideal balance of tone. For the inner rim, small-pored hardwoods that provide superior brightness and projection are interlaminated with dense, large-pored hardwoods offering warmth and fullness. This synergy of structurally divergent hardwoods produces a powerful, well-rounded richness of tone that is the hallmark of Kawai pianos.

Vertically Laminated Bridge

The bridge performs the vital task of transferring the vibrations of the strings to the soundboard. GX bass bridges are made of the highest quality hard maple or beech. Treble bridges are vertically laminated with 13 layers of maple and mahogany for maximum strength and optimal transfer of sound energy. The GX-6 features a single, continuous bridge that helps to smooth the transitions between bass and treble registers.

SOLID (Stretcher Over-Lap Integrated Design)

SOLID construction creates an exceptionally rigid foundation to support string tension. First, the pinblock is fitted to the plate. Then, the pinblock and over-lapping stretcher bar are integrated into a single structure and solidly anchored to the rim. The extraordinary thickness of the stretcher bar exemplifies the structural integrity of this sturdy framework designed to ensure stable tuning and powerful tone.

V-Pro Plate

The plate is the acoustically-neutral iron superstructure of the piano over which the strings are tensioned.

All GX Series plates are molded using the Vacuum Mold Process (V-Pro) with “Crossbone Design.” The result is a plate that is strong, stable and beautiful.
