Yamaha DC1XEN Disklavier ENSPIRE Grand PianoIntroducing the Yamaha Disklavier C1X ENSPIRE Grand Piano The DC1XEN is the first Disklavier CX series grand piano. Refinements in component quality make it a worthwhile upgrade from the DGB1KEN and DGC1EN, including specially selected hammers and a redesigned soundboard crown for improved resonance. At 5'3'' in length the instrument is big enough to produce a real depth of sound while remaining compact. Player pianos have been around for many years.
