Casio's Flagship Privia

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.

Realistic piano sound with AiR

To reproduce the sound of the finest acoustic grand pianos, the Privia PX-870 features Casio's proprietary AiR (Acoustic and intelligent Resonator) processor. Accessing more than three times the memory of the previous generation, the AiR processor utilizes grand piano samples recorded at four dynamic levels of sampling to deliver grand piano sounds with long natural decays and remarkable expression. To further the grand piano experience, AiR adds realism by simulating the sound of the open strings when the dampers are raised by the pedal.

Sound Projection system fills the room with sound

At Sweetwater, we're impressed by the acoustics of the Privia PX-870, thanks to its Sound Projection system. This powerful 40-watt, 4-speaker system fills the room with rich, detailed sound. Best of all, the sound radiates from various places on the PX-870's cabinet, much like a traditional grand piano. Beyond that, you'll enjoy a balanced sound across the entire frequency range, at any listening volume, by virtue of this digital piano's Volume Sync EQ.

Scaled hammer action provides authentic piano feel

You'll deliver an expressive performance, thanks to the Privia PX-870's Tri-Sensor II Scaled Hammer Action piano keys, which are accurately scaled across the entire key range. Beyond that, simulated ebony and ivory textures provide an authentic touch. The PX-870's touch sensitivity is adjustable, allowing you to tailor it to your playing style, while its customizable hammer response accurately reproduces the delay between when a key is struck and a note is produced.

  • 88 full-size scaled hammer action keys give you authentic piano playability

What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Rated 5/5

Love this piano!

Assembly was easy! The instructions provided were comprehensive and clear. I easily found a youtube instruction video as well (done by Sweetwater). which was super helpful. So I was happily playing the piano on the same day I received it! The sound is impressive! So authentic. The many features make it fun to play around with songs I might not have tried with a "regular" piano. Very satisfied!!

Many of the keyboardists here at Sweetwater have fond memories of Casio that go all the way back to when we first started playing, and that's often kept us coming back for decades. Today, we're happy to point players to Casio keyboards, no matter how long they've been playing - even if they've never played at all. In fact, we've set up many beginners with Casio LK series Lighted-key models, and they've regularly raved about how easy these keyboards make learning. Likewise, several of the solo performers at Sweetwater swear by their fully loaded Privia and other advanced lines, which provide top-notch accompaniment and more. And if you stop by the Sweetwater Piano Showroom, we'll be happy to show you the latest Casio home piano - all providing amazing value and style.
