PX-S1100 vs PX-S3100 Key Specs
Key action technology
The Casio Privia PX-S1100 features a Smart Scaled Hammer Action keyboard. This system reproduces the individual characteristics of each of the 88 keys, delivering a superior response suitable for any player. In contrast, the Casio Privia PX-S3100 utilizes a standard Hammer action keybed. While both provide 88 weighted keys for realistic playing, the PX-S1100’s scaled hammer action offers a more nuanced touch response that varies across the keyboard range. This distinction matters if you prioritize detailed key scaling in your instrument choice.
Sound engine quality
The PX-S3100 employs Casio’s Multi-dimensional Morphing AiR Sound Source. This engine accurately generates unique resonances of a grand piano, delivering vivid, harmonically rich sound with dense overtones for all 88 keys. The PX-S1100 offers 18 tones, including a German concert grand piano with damper and string resonance. However, the PX-S3100’s speaker system features a strengthened diaphragm for cleaner highs and an improved inner structure for more dynamic lows. The PX-S3100 provides a more sophisticated and dynamic sound profile.
Connectivity options
The PX-S1100 supports both Bluetooth MIDI and Bluetooth Audio via the included WU-BT10 adapter. It also features built-in 1/4" outputs and high-resolution USB-MIDI connectivity. The PX-S3100 includes Bluetooth audio connectivity for wireless streaming from smartphones or tablets. It also allows wireless control via the Chordana Play for Piano app. The PX-S1100 offers broader connectivity versatility with dual Bluetooth capabilities and direct audio outputs, making it more suitable for studio integration without extra adapters.
Physical dimensions
Both pianos are designed for slim profiles, but the PX-S3100 is marketed as the world’s slimmest 88-key digital piano with hammer action, featuring a depth of just 232 mm. The PX-S1100 is 43% smaller than previous generation Privias. The PX-S3100 has a flat, mirror-like top panel with touch controls and a gold logo. The PX-S1100 dimensions are listed as 3.58 inches in width in its bundle specs, which seems to refer to depth. The PX-S3100 offers a more distinct, ultra-slim aesthetic.
Included accessories

Which Casio Privia Model Fits You
You want rich, dynamic piano sound
The PX-S3100 uses Multi-dimensional Morphing AiR Sound Source for vivid, harmonically rich audio. Its strengthened speaker diaphragm delivers cleaner highs and more dynamic lows. This engine captures grand piano resonances across all 88 keys, offering a superior tonal experience compared to the standard tones found in the PX-S1100.
You need versatile instrument tones
The PX-S1100 provides 18 preset tones, including German concert grand, electric pianies, organs, and strings. It features damper and string resonance for a natural feel.
