As the flagship model in the series, the CLP-685 boasts a GrandTouch Keyboard action that features the individual key counter weights found in a grand piano for unrivaled realism in the resistance and return of each key. CFX and Bösendorfer samples absolutely sing through the powerful 300W sound system with Spruce Cone speakers. Spruce wood is used in the sound boards of Yamaha acoustic pianos because of its superior tone quality, and that same wood is used in the CLP-685 speaker cones. You will lose yourself in the sound of the binaurally-sampled CFX which is a totally immersive headphone experience. Selecting Voices and adjusting settings is easy using the intuitive user LCD interface.
