NEW MOTHERBOARD AND SPEAKERS DEVELOPED IN PARTNERSHIP WITH ONKYO. The additional speakers on this model send sound from the top and the bottom of the piano, much like the soundboard of a grand piano sends sound vibrations in two directions. Kawai digital and hybrid pianos are well-known for providing more power output than similarly priced competitors, but Kawai also installs exceptionally high-quality speakers to make the best use of that power. The result is volume and dynamic range that is always musical across the entire scale.
