Enjoy an authentic grand piano experience with Casio's Privia PX-870. Casio's multi-dimensional AiR processing provides true-to-life piano sounds, while 88 full-size scaled hammer action keys with simulated ebony and ivory textures ensure realistic playability. Besides a great-sounding four-layer stereo grand piano, the PX-870 comes with 19 additional tones to add dimension to your playing. And everything will sound larger than life, thanks to this digital piano's 40-watt, four-speaker Sound Projection system. Teachers will appreciate Casio's Duet Mode, which allows two people to play the same notes simultaneously. And along with a stylish modern design including a sliding key cover, music stand, and three-pedal board, the Privia PX-870 will look great in any setting.
