Rim and Beam Construction
Rim and Beam Construction
The RX 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.

Four-Way Joinery
Kawai joins the beams to the inner rim using four independent joinery techniques. Each beam is : (1) doweled, (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 V-Pro Plate

Plate Construction
The plate is the acoustically-neutral, iron superstructure of the piano over which the strings are tensioned. All RX Series plates are molded using the Vacuum Mold Process (V-Pro). Added strength comes from the plate's Crossbone Design. The result is a plate that is strong, stable and beautiful.

Kawai RX 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. RX 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 RX Series Hammers
Mahogany Hammer Mouldings
Mahogany hammers are lightweight and extremely responsive. Found on only the finest grand pianos, mahogany is used for hammer mouldings on the entire line of RX Series Grand Pianos.
Kawai Hard Finish Music Rack
Hard Finish Music Rack
The music rack must support a variety of music books and writing implements. Kawai's Hard Finish protects the music rack from being scratched or marred... preserving the piano's beauty. The Hard Finish Music Rack is an exclusive feature of all RX Series grand pianos in Polished Ebony.
Kawai Soft Fall Fallboard
"Soft Fall" Fallboard
The RX Series fallboard is designed with a dual-damping mechanism so sensitive that it was dubbed "soft fall." The ultra-slow closing system protects hands, fingers and the piano's finish from the harm that a jarring close might cause.
