TRADITION AND TECHNOLOGY ARE INDISPENSABLE ELEMENTS OF PIANO TONE. TRADITION LAYS THE FOUNDATION FOR OUR DISTINCTIVE TONAL CHARACTER, TECHNOLOGY EMPOWERS IT WITH LIFE, BREADTH, AND DEPTH THAT LASTS FROM GENERATION TO GENERATION.
CORE is an acronym that stands for "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.
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.
The soundboard is the heart of a piano's tone. Kawai uses only straight-grained, quarter-sawn solid spruce for GX BLAK Series soundboards. Each one is strategically tapered to provide the proper degree of resonant movement in each region. Only soundboards that exceed our demanding resonance standards are selected for use in the GX BLAK Series grand pianos.
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 and GX-7 feature a single, continuous bridge that helps to smooth the transitions between bass and treble registers.
Hard brass agraffes – positioned through precise CNC drilling of the iron plate – ensure accuracy of string alignment, spacing and angles for the greatest uniformity of tone. They also allow the most precise measurement of “speaking length" for the strings and provide smooth string movement for ease of tuning.
