The K600 is the tallest model in the K series and as such you can expect excellent tonal quality and performance, comparible to that of many grand pianos. Featuring key elements of other K series models, such as Kawai's Millenium III Upright Action, Duplex Scaling, extended keys with Neotexz surfaces and mahogany core hammers, the K600 model builds on this to deliver an exceptional instrument. The Duplex Scaling is improved, and agraffes are used to ensure a more efficient transmission of sound from the strings to the soundboard, allowing the strings to vibrate in a more controlled way, improving the dynamics and ensuring a more successful support.
