Kawai GX BLAK Series Rim Construction
Rim and Beam Construction
The GX BLAK Series rims are built using cross-binding and lamination techniques to form a structure that is, pound for pound, stronger than steel. The beams are made of select hardwood laminates, glued together under pressure, making them virtually isotropic (equally strong in all directions) and impervious to weather changes and warpage.
Kawai GX BLAK Series Four-Way Joinery
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

V-Pro Plate
The V-Pro (Vacuum Mold Process) plate on the Kawai GX BLAK 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.
