Casio PX S1100 CB

Casio Privia PX-S1100 CB — Slim 88-Key Stage Piano with Grand Piano Touch

The Casio Privia PX-S1100 CB is a full 88-key digital piano in the limited-edition Calm Blue finish, built for players who want authentic grand piano feel without surrendering a room. Casio's high-density mounting compresses the keyboard, speakers, and circuit board into a body just 232 mm deep, the slimmest 88-key hammer-action digital piano with built-in speakers in its category.

What Sets the Privia PX-S1100 Apart

Most stage pianos trade slimness for sound or vice versa; this model refuses that compromise. The 88-Key Digital Scaling system individually weights each key's response to mimic the heavier bass and lighter treble feel of a real grand, while Hammer Response, Key-Off Response, String Resonance, and Damper Resonance recreate acoustic instrument behavior.

Keyboard and Touch

Each of the 88 keys carries its own scaled weight, and the ebony- and ivory-textured surfaces stay grippy through long practice sessions.

• Keyboard: Smart Scaled Hammer Action — weighted keys with per-note scaling for authentic grand feel
• Keys: 88 — full concert range for classical repertoire and band use
• Touch Response: 5 sensitivity levels plus off — match the action to your playing style

Sound Engine and Speakers

The Multi-Dimensional Morphing AiR engine samples every note with overtones and body resonances, then layers in mechanical detail that responds to playing dynamics. A 192-note polyphony budget keeps sustained pedal tones intact when layering two sounds.

• Sound Source: Multi-Dimensional Morphing AiR — detailed piano tones with evolving overtones
• Polyphony: 192 notes — headroom for layered voices and complex arrangements
• Speakers: 2 × 16 cm × 8 cm oval drivers, 8 W + 8 W amplification — full-range sound without external monitors

Connectivity and Portability

Wireless connectivity runs through the included WU-BT10 adaptor, which streams Bluetooth audio and sends MIDI over Bluetooth Low Energy to apps like CASIO MUSIC SPACE. Battery operation frees the instrument from the wall socket.

• Wireless: Bluetooth 5.0 (Audio A2DP/SBC, MIDI over BLE) via WU-BT10 — wireless streaming and app control
• USB: Type A and Type B — flash-drive recording and class-compliant MIDI to a computer
• Power: AC adaptor or 6 × AA batteries (approx. 4 hours) — cable-free performance anywhere

Who the Casio PX-S1100 CB Is For

The Casio Privia PX-S1100 CB is the right choice for intermediate and advanced pianists who need a full 88-key weighted action in a body that fits a small apartment, dorm room, or touring rig. Gigging keyboardists will appreciate the 11.2 kg weight, AA battery operation, and Line Out jacks. Home players get authentic grand piano touch, Bluetooth audio streaming, and a built-in lesson function with 60 songs and Part ON/OFF for hands-separate study. Students moving up from smaller keyboards will find the full range and 192-note polyphony a meaningful step toward realism. Two headphone jacks make late-night practice neighbor-friendly.

Casio and the Privia Line

Casio entered the music industry in 1980 with electronic keyboards. The Privia series set out to deliver grand piano feel in a fraction of the cabinet size, and the PX-S1100 continues that mission with the slimmest body the line has produced. Concert pianist Hayato Sumino, a CASIO ambassador and Steinway Artist, has performed with the PX-S1100, citing its natural touch as a defining strength.
