The most precise piano action of the world
Through the combination of material strength, stability, precision and reliability is Kawai's ULTRA RESPONSIVE™ leading action. The hammer heads are made of 100% pressed "Premium" wool. To make the action resistant to climatic and seasonal changes in temperature and humidity, Kawai pioneered the use of aluminum action rails and hammer rest rails, and construct certain highly stressed components of friction-reducing, high-impact ABS Styran.
Soundboard of the special class
The Kawai wood technology uses all of senses ... seeing, smelling, feeling, to select the best woods. The soundboards of the K-series are finished of massive, very straight-grained spruce, that is very carefully selected, asymmetrical vaulted and scientifically tested, to fulfil Kawai's high demands to the resonance behavior and to the best sound.
The back posts construction
The laminated back posts of the K-series are designed for maximum rigidity to provide enhanced tuning stability for decades of reliable performance.
Other finishes available for the Kawai K15 include:
Kawai K15 MEP - Polished Ebony
Kawai K15 MMP - Polished Mahogany
