The Casio PX-870 is a console-style digital piano with a powerful four-speaker system and Tri-Sensor Scaled Hammer Action, delivering room-filling sound with a lid simulator and clean furniture-style design for home players.
The Casio PX-870 remains a benchmark for the furniture-style digital piano market under $1,000. While Casio was once viewed strictly as a budget alternative, the PX-870's AiR Sound Source and 40-watt, four-speaker Sound Projection system deliver a depth of field that rivals more expensive Yamaha Arius models. The concert grand patch is particularly lush, benefiting from adjustable string and damper resonance that adds a convincing layer of organic 'air' to your performance.
The Tri-Sensor Scaled Hammer Action II provides a satisfying, tactile weight. The simulated ebony and ivory textures are a highlight, offering superior grip during long practice sessions, though the action can feel slightly 'bouncy' on the key return compared to a high-end acoustic. My main gripe lies in the user interface; like many minimalist consoles, changing deep settings often requires memorizing cumbersome key-button combinations, which feels a bit dated. However, the inclusion of the 'Hall Simulator' and a dedicated USB-to-device port for MIDI/audio recording makes it a versatile tool for the intermediate student. It's a workhorse that prioritizes acoustic realism and projection over flashy digital bells and whistles, making it an excellent value for home learners and budget-conscious enthusiasts who need a primary practice instrument.
