Compare the Kawai CA Series
The Kawai Concert Artist series is designed to offer a progression of realism, from the accessible CA401 to the flagship CA901. While all models feature wooden keys and premium build quality, the differences in action, sound engine, speaker system, and cabinet design become increasingly significant as you move up the line.
