Kawai KCP90 and CL26 Uses the AHA IV-F Graded-Hammer Action
Kawai KCP90 and CL26 Digital Pianos use the
Advanced Hammer IV-F (AHA IV-F) Keyboard Action which has been
developed to represent the distinctive touch of an acoustic grand piano, with its remarkable springless design providing
consistent upward and downward motion for a smooth, natural
piano playing experience. Moreover, just as acoustic pianos utilize heavier bass hammers and lighter treble hammers, the AHA IV-F keyboard action also employs different hammer weights, appropriately graded for each playing range. Such attention to detail allows greater stability during fortissimo passages, while
preserving delicate pianissimo control, to satisfy the demands of
even the most discerning pianist.
