Supreme Sound A grand piano s large body and complex structure create a range of resonances that give it a rich, detailed and unique sound. Casio s original Multi-dimensional Morphing AiR Sound Source accurately generates the unique resonances of a grand piano. The Privia PX-S1100 delivers a vivid, harmonically rich sound thanks to the dense overtones of each individual string for all 88 keys tuned for its unique speaker system. The expressive changes in timbre created by the instrument s response to key velocity and temporal change are finely controlled, giving you the freedom to truly express yourself in all styles of playing, from soft and nuanced to dynamic and powerful. Powerful Speaker System The speaker system of the Privia PX-S1100 features a strengthened diaphragm for a cleaner, richer high end and an improved inner structure design for a more dynamic low end.
