Upright Piano Kawai KS5F.
Soundboard & Ribs (soundboard).
The most important sound-producing parts of an acoustic piano are the Soundboard and the Ribs (wooden bars placed diagonally on the soundboard). Both the materials used and the way they are assembled greatly affect the volume and quality of the piano's sound. The company only uses large, straight solid Spruce wood to create high-quality Soundboards and Ribs bridges that reproduce excellent resonance across the entire sound spectrum.
Plate (Frame).
The plate on the Kawai Piano is made of high-quality cast iron for hardness that can withstand a string tension of over 20 tons (acoustic piano bass strings). To withstand this type of pressure, the company builds the plate to the most exacting specifications and incorporates the plate's natural resonance into the overall design to ensure outstanding acoustic performance. The plate has the effect of maintaining the structure of the instrument and transmitting resonant sound.
Bridges.
The bass and treble bridges play the role of transmitting vibrations from the strings to the soundboard. To ensure superior Kawai Piano sound, the company used solid Rock Maple wood to make the Bridges and carefully cut them to eliminate uncontrolled "wild strings" that cause tinnitus echoes. , retaining only the transparent and delicate sound.
Back Posts (back frame).
Back Posts are pillars behind the back of an Upright Piano that provide support for the Frame (Plate). On the Kawai KS5F upright piano, the back posts structure is firmly designed with many layers to help increase the stability of the piano. (Action) when tuned over decades.
Pinblocks.
Pinblock, also known as pin, is the part that holds the strings. Pinblock is one of the most important components in an acoustic piano, and must be manufactured and finished to the highest quality standards to ensure stability when tuning . With Kawai Piano, the company creates pinblocks from the finest hard Rock Maple wood and drills each adjustable pin hole with meticulous machining techniques. Kawai has used Nickel material to make the pin to help prevent rust, make it stronger and more durable; At the same time, the pin latch is beveled with a spiral groove to make tuning easier.
Keys (keys).
The keys on every Kawai upright piano are individually weighted and balanced to ensure consistent key response, with excellent repetition and feedback.
In addition, some kawai upright models use Ivory covering the white key surface, black keys use high-quality Ebony wood.

The outstanding feature of the Ivory key line is that it is brittle, resistant to cracking and discoloration extremely well.
