Kawai CA901 Rosewood

A "Concert Artist" Designed to Recapture the Feel of an Acoustic Piano Daily

The Kawai CA901 embodies the "piano first" spirit of the range: an elegant furniture instrument, a demanding action, and sound reproduction designed to serve piano playing, from technical practice to repertoire pieces. It targets students in training and advanced pianists who want a realistic response, great tuning stability, and the comfort of a digital piano without the maintenance constraints of an acoustic piano.

Keyboard Design

The Grand Feel III action emphasizes the "grand piano" sensation: solid wood keys for natural inertia, Ivory/Ebony Touch finish for consistent grip, and escapement simulation to replicate the slight resistance typical of an acoustic mechanism. With 3 sensors per key, detection remains precise even during rapid repetitions, and the velocity curves (Light, Normal, Heavy, Off) allow fine adjustment of touch response according to your technique and dynamics.

Sound Quality

SK-EX Rendering is based on 88-note piano sampling of the Shigeru Kawai EX Concert Grand, complemented by other models (EX, SK-5, K60). Combined with Harmonic Imaging XL, this sound base aims for rich harmonics and credible resonance across all dynamics. The CA901 offers 96 voices (pianos, strings, organs, modern sounds) and 256-note polyphony to play in layers, with pedals, without cutoffs. When using headphones, Spatial Headphone Sound enhances spatial sensation and reduces fatigue during long sessions.
