Introducing the Sonix SXP20 digital piano with bench

At the top of Sonix’s digital piano series, the SXP20 is a premium product at a mid-range price. Beautifully designed with a streamlined cabinet, chrome hardware and a black satin woodgrain finish, this upright is more than just a functional piano; it’s a stylish piece of furniture to enliven any room.

The SXP20 is easy to move around thanks to its wheels, and will never need tuning or maintenance making it a truly hassle-free musical companion. With one touch, a discreet control panel silently slides out to reveal a host of controls, with various sounds and functions at your fingertips.

This is also an excellent model for those looking to improve their playing. A headphone port is included so you can practice in ‘silence’ and duet mode lets you split the piano in two for lessons, with half for you and half for the teacher.

Sophisticated response

With a full 88 velocity sensitive keys, the SXP20 allows you to play and learn without frustration or limitation. The graded hammer action makes for a truly enjoyable playing experience, and aided by impressive 189 note polyphony, the SXP20 can make you feel like you’re on a concert grand!


4 speakers and expansive body

Enjoy concert hall sound through 4 finely tuned stereo speakers integrated throughout the cabinet enclosure, boosted further by an expansive cabinet shape. The end result is an amazing blend of digital power combined with beautiful acoustic overtones.




Sculpt your own sound

With one touch, the discreet control panel silently slides out to reveal a host of controls. This includes a metronome function, a demo song player, and the ability to easily change between any of the 32 selectable on-board voices. A volume dial means you can go from relative quietness to maximum power in an instant, and this piano really packs a punch. You can even play your own audio files through it with Bluetooth connectivity!


A classy finish

The SXP20 and matching bench are both wrapped in a soft black satin woodgrain finish. Shiny chrome hardware makes for some attractive accents to the look, helping to make the piano stand out. The control panel is intuitive to use alongside the manual, giving you access to a wide variety of musical expression and nuance. Bluetooth, MIDI and USB ports are all integrated seamlessly too.






Includes matching bench with storage space!

To complete the package, the SXP20 is supplied with a sturdy Sonix keyboard bench in a matching black finish, pairing perfectly with the piano. With strong wooden legs and body as well as a smooth padded seat, this bench looks great alongside the SXP20! For added convenience, the top lifts up to reveal some handy storage space inside, an ideal place to keep your sheet music.
