Design and Portability

One of the most distinctive aspects of the PX-S1100 is its ultra-slim design—at just 232mm (9.1″) deep, it’s one of the most compact 88-key digital pianos on the market. Casio achieves this without sacrificing key size or realism.

• Weight: Only 25 lbs (11.2 kg)
• Finish Options: Black, White, and Red

The touch-sensitive, illuminated buttons and glossy top panel add a futuristic, minimalist aesthetic. This design makes it ideal for modern apartments, small studios, or mobile gig setups.

Casio PX-S1100 vs PX-S1000

In this Casio Privia S1100 review, let’s take a quick look at what’s new in the PX-S1100.

The Casio PX-S1100 is the direct successor to the PX-S1000 which we released in 2019.

Both models share the core design & features:

• Slim, compact body
• Smart Scaled Hammer Action
• AiR Sound Source
• 192-note polyphony
• Bluetooth functionality (PX-S1100 added Bluetooth audio, PX-S1000 had only Bluetooth MIDI)

What Improved in the Casio PX-S1100?

1. Bluetooth Audio Support (in addition to MIDI)
2. Enhanced Piano Tones with more refined resonance and speaker tuning
3. Simplified Connectivity with USB Type B (no USB adapter required)
4. Improved build quality and updated internal firmware

Thus, the PX-S1100 replaces the PX-S1000 as the improved version within the Casio Privia PX-S line. It keeps the same form factor and philosophy but with meaningful upgrades for modern users.

Sound Quality – AiR Sound Source

The Casio PX-S1100 uses the Multi-dimensional Morphing AiR (Acoustic and Intelligent Resonator) sound engine, known for delivering a natural piano tone with rich dynamics.

• Main Grand Piano Sound: Bright, expressive, and customizable via Casio’s Chordana Play app
• Polyphony: 192-note polyphony ensures seamless performance
• Built-in Tones: 18 high-quality voices including electric pianos, organs, strings, and harpsichord

Compared to its predecessor, PX-S1000, the S1100 features refined speaker tuning and enhanced damper resonance, resulting in a more immersive sound experience, particularly when used with headphones.

✅ Great for: Classical music, pop, ballads, and ambient compositions.

Key Action – Smart Scaled Hammer Action

The Smart Scaled Hammer Action Keyboard simulates the response of a real acoustic grand piano. The keys are:

• Fully weighted and graded (heavier in the lower range, lighter in the upper)
• Textured with a matte finish for grip
• Quiet and responsive, even during fast passages

Compared to other digital pianos in this price range (like Yamaha P-145/P-143 or Roland FP-10), the PX-S1100 holds its own with a more refined key feel and better control for nuanced dynamics.

Touch Sensitivity

Moreover, the PX S1100 offers five levels of touch sensitivity, which let players customize how the keyboard responds to their playing dynamics. Whether you’re a light-touch beginner or an expressive performer with powerful keystrokes, you can adjust the response to suit your playing style.

This adds both versatility and nuance, allowing you to better match the feel of the PX-S1100 to a wide range of musical genres and techniques.

Speakers and Headphones

Despite its slim form, the Casio PX-S1100 delivers impressive sound projection through its built-in speaker system. Whether you’re practicing at home, performing in a small venue, or using headphones for private sessions, the Privia S1100 offers versatile audio options that cater to different environments and preferences. Let’s take a closer look at how it performs in both open-air and silent practice situations.

• 2 x 8W stereo speakers deliver clear, surprisingly full sound for the piano’s size.
• Ideal for small room performance or practice
• Stereo headphone output with detailed spatial simulation
• Audio Line Out allows connection to external speaker system

You can also connect powered monitors or use Bluetooth audio streaming to play along with music from your smartphone.
