Kawai GL Series Strength
STRENGTH ALLOWS A PIANO TO PERFORM WITH INTEGRITY AND AUTHORITY OVER TIME. GL SERIES PIANOS ARE BUILT WITH REMARKABLE STRENGTH TO THRIVE AMID THE RIGORS OF LONG-TERM USE.
Kawai GL Series Stretcher Bar
Stretcher Over-Lap Integrated Design (SOLID) creates an exceptionally rigid foundation to support string tension. With SOLID construction, the pinblock is fitted to the plate. The pinblock and over-lapping stretcher bar are then integrated into a single structure and solidly anchored to the rim. The stretcher bar itself boasts an extraordinary thickness that exemplifies the structural integrity of this sturdy framework designed to ensure stable tuning and powerful tone.
Kawai GL Series Steel Reinforced Keybed
To support the weight of the action over time, the keybed is made of sturdy, laminated hardwoods and reinforced with a steel beam that adds strength and rigidity to prevent energy loss.
Kawai GX BLAK Series Steel-Reinforced Anti-Warp Keyslip
A piano's "keyslip" is the long, horizontal piece of wood that covers the front faces of the keys. Because it is made of wood, a keyslip can warp or bend with changes in humidity causing keys to stick. GL Series keyslips are reinforced with a steel inside liner that prevents warping or bending in any direction. Keys move freely as the keyslip remains straight and evenly distanced from the key faces throughout the life of the piano.
Kawai GX BLAK Series Four-Way Joinery
Beams are joined to the inner rim using four independent joinery techniques in a single process. Each beam is: (1) fitted with a hardwood dowel, (2) mortised into the inner rim for precise fit, (3) glued, and (4) secured with hardened screws for complete bonding through the entire thickness of the inner rim for a tremendously secure rim-to-beam connection.
Kawai GX BLAK Series V-Pro Plate
The V-Pro (Vacuum Mold Process) plate on the Kawai GL Series is the acoustically-neutral gray iron framework of the piano on which the strings are applied. As the “backbone” of the piano, the plate must be designed and built to ensure stability while enduring up to 18 tons of string tension. At the same time, it must be molded with sufficient precision to ensure exact string lengths. The V-Pro process produces a sturdy plate that is dimensionally accurate and consistent, with added strength provided by the “crossbone” design of the plate struts. With the application of a lustrous finish and the addition of highly-polished solid brass finials, the result is a plate that is strong, stable and beautiful.
Kawai GX BLAK Series Pinblocks and Tuning Pins
The Multi-Grip pinblock on all GL Series grand pianos is fully laminated with a minimum of eleven cross-banded layers of North American hard maple for maximum strength and balanced torque. Tuning pins are made from the finest carbon steel, machine-threaded for maximum continuous torque and nickel plated to enhance beauty and provide long-term protection.
