The speakers have been upgraded to deliver improved frequency response, volume, and articulation. What makes these speakers stand out is their design – they are engineered to produce accurate sounds regardless of the piano’s placement in a room.

Trust me when I say that these speakers enhance the realistic sound of Casio’s Privia series, contributing significantly to its authentic playing experience.


Transitioning from the impressive sound quality of its speakers, let’s now focus on another standout feature of the Casio Privia PX-S3100: its portability.

Don’t be deceived by its full-size and fully weighted keyboard; this digital piano is remarkably compact and lightweight. Here’s what makes it so portable:

– Its slim design, weighing less than 25 lbs, makes it easy to transport for gigs or simply move around your home.

– Despite being robust in features and functionality, it measures a mere 52 x 9.1 x 4 inches, making it one of the slimmest digital pianos available today.

– With optional battery power that utilizes 6 AA batteries, you can play music wherever you want without having to worry about finding a power outlet.

This level of portability truly sets the PX-S3100 apart.


When you choose the PX-S3100, you’re not just getting a digital piano with impressive sound and portability. There’s more to it. You’ll have an array of effects at your disposal to enhance your music. The PX-S3100 comes equipped with a variety of DSP effects, including chorus and reverb. These effects can be applied to every onboard tone. By adding depth and texture to the sounds, they create more rich and immersive performances.

You’ll find four types of reverb for mimicking different environments, two types of chorus for thickening up your sound, brilliance adjustment for tonal control, and 3D stereo sound enhancement for a wider sonic image. On top of that, string resonance simulates the harmonic relationships between vibrating strings, while damper resonance adds realism when the sustain pedal is used.

It’s quite remarkable how these features can transform your music experience!


Imagine having a world of sounds at your fingertips, ready to inspire and elevate your musical journey – that’s exactly what you get with the PX-S3100’s diverse sound collection.

Vs Yamaha P-125

Let’s dive in and compare the PX-S3100 with a popular competitor, the Yamaha P-125.

The PX-S3100 excels in sound variety with 700 onboard tones compared to Yamaha’s 24 voices.

You’ll also appreciate Casio’s improved speakers and wireless capabilities for control and recording.

Design-wise, the PX-S3100 is sleeker and lighter than the P-125, making it easier to carry around.

However, some players may find Yamaha’s interface more user-friendly as it doesn’t require deep menu diving like Casio does for advanced features.

Both are great choices, but your final decision will depend on your specific preferences and requirements.

Vs Roland FP-30X

When it comes to sound quality, the Roland FP-30X stands out with its SuperNATURAL Piano sound engine, delivering a rich and authentic tone. On the other hand, the Casio Privia PX-S3100 offers a whopping 700 onboard tones, providing more variety and versatility.

In terms of key action, both pianos feature weighted keys that mimic acoustic pianos. However, the Casio PX-S3100 takes it a step further with its Smart Scaled Hammer Action Keyboard, which simulates the textures of ebony and ivory, enhancing the playing experience.

When it comes to portability, both pianos are designed to be easily transported. However, weighing in at just 25 lbs., the Casio PX-S3100 is significantly lighter than the Roland FP-30X, making it a more convenient option for those on the go.

Overall, while the Roland FP-30X excels in sound quality, the Casio PX-S3100 offers a wider range of tones and a lighter weight for increased portability. Ultimately, these two rivals’ decisions depend on your specific needs and preferences.

However, if you prioritize high-end features over price point, there might be slightly pricier alternatives worth considering too.
