Size: L:154cm W:65cm H:131cm Comes with a unique "X" back post design aimed to increase bass quality and general tuning stability. The Yamaha "X" series Professional Upright Pianos are for those who want a serious replacement for their small grand pianos. These pianos are a significant jump over the U1 and U3 pianos. They have a star shaped back frame to better balance the overall tension. Hammers are made of a higher quality felt from both Yamaha and Renner of Germany, and the scaling of the strings are a slight improvement from the U series pianos. The action has a more precise feel to it, contributing to a more lively and controlled response. There is a tone escapement slot in the front cover of the cabinet for increased clarity. Pianos of the 131cm range include the X, YUA, YUX, UX, UX3, UX30 and the WX3
