The Casio PX-870 occupies a unique position in the digital piano market as the flagship of the Privia range. It is defined by its ultra-compact, slimline cabinet which allows it to fit into smaller living spaces without sacrificing the presence of a full console piano. The instrument is designed to challenge the traditional limitations of compact digital pianos by offering a more immersive acoustic experience.
AiR Sound Engine and Technology
At the core of the PX-870 is Casio’s Multi-dimensional Morphing AiR (Acoustic and intelligent Resonator) sound source. This technology uses thorough sampling of a concert grand piano to deliver high levels of detail. Beyond the basic piano tone, the engine simulates complex acoustic phenomena including:
- String Resonance: The sympathetic vibration of unplayed strings.
- Key Action Noise: The subtle mechanical sounds of keys being pressed and released.
- Dynamic Range: A wide variation of tone that responds accurately to the player's touch and velocity.
Sound Projection System
One of the standout features of the PX-870 is its innovative Sound Projection speaker system. Unlike standard digital pianos that direct sound solely downwards or towards the player, the PX-870 projects sound from both the front and the back of the cabinet. This dual-projection method is intended to fill a venue more effectively and recreate the natural dispersion of sound found in a traditional upright piano.
Market Comparison
When compared to other digital pianos in the market, the PX-870 competes with models such as the Roland RP701 and the Kawai CN301. While higher-end models like the Kawai CA901 or Roland HP704 offer different cabinet styles and action technologies, the PX-870 focuses on providing flagship-level sound characteristics within a more accessible price point of approximately £630. It serves as a more advanced alternative to entry-level models like the Casio AP-300 or the Gear4Music VISIONKEY-500.
Target Audience
The PX-870 is suited for a wide range of pianists, from intermediate students to advanced players who require a space-saving instrument that does not compromise on tonal authenticity. Its combination of string resonance and realistic key noise makes it a viable tool for those looking to practice with the nuance required for concert grand performances.
