Kawai CA901 White

CA901: Kawai's High-End Model Designed for Acoustic-Style Playing at Home

Designed to offer an experience close to an acoustic instrument without the tuning hassles, the Kawai CA901 aligns with the brand's "Concert Artist" philosophy: prioritizing touch, resonance realism, and wide sound projection in an elegant cabinet. It targets both progressing pianists seeking a reliable and inspiring instrument and demanding musicians wanting true control, nuance, and sonic presence in a digital home piano.

Keyboard Design

The CA901 focuses on a distinctly pianistic approach: Grand Feel III action for reproducing the touch of a grand piano, with solid wood keys designed for stability and durability. The Ivory/Ebony Touch surface enhances finger grip, while the escapement simulation replicates the subtle resistance typical of acoustic mechanisms. For precise control, each key features 3 sensors, useful for rapid repetition and fine dynamics. Finally, the velocity curves (Light, Normal, Heavy, Off) allow you to tailor the keyboard response to your technique, repertoire, and playing habits.

Sound Quality

The sound engine is based on the SK-EX Rendering sound source with 88-note sampling of the prestigious Shigeru Kawai EX Concert Grand and other Kawai models (EX, SK-5, K60). The Harmonic Imaging XL technology aims for detailed harmonic and resonance reproduction, delivering a more expressive piano from pianissimo to fortissimo. The CA901 offers 96 voices (pianos, strings, organs, modern sounds) and a 256-note polyphony for comfortable playing with pedals and layering. When using headphones, the Spatial Headphone Sound function enhances the sense of space and reduces "in-the-head" listening, ideal for long sessions in apartments.
