Kawai ES520B Portable Stage Piano — Concert Grand Sound in a 14.5 kg Package

The Kawai ES520B is a portable 88-key stage piano that delivers flagship-grade concert grand sound in a 14.5 kg package. Built around the Responsive Hammer Compact II action and Progressive Harmonic Imaging engine, it reproduces the hand-built Shigeru Kawai SK-EX and Kawai EX concert grands through full 88-key stereo sampling. A 40 W on-board speaker system fills a room without external amplification, while the molded unibody case keeps the instrument light enough to carry under one arm.

What Sets the Kawai ES520B Apart in the Portable Piano Tier

What separates this model from other portable pianos in its tier is Progressive Harmonic Imaging with 88-key stereo sampling of the flagship SK-EX concert grand. The triple-sensor Responsive Hammer Compact II action with matte key surfaces delivers nuanced dynamic response, while the Virtual Technician function exposes 17 piano-adjustment parameters — including damper resonance, string resonance, and 88-key user tuning — for shaping the instrument's character to taste.

Keyboard Action and Touch Response

The keyboard is the heart of any stage piano, and the ES520's RHCII action mirrors the distinctive feel of an acoustic grand.

• Action: Responsive Hammer Compact II — spring-less design with consistent up/down motion
• Triple-sensor detection — captures rapid re-strikes and key-release velocity for expressive playing
• Hammer weights graded across registers — heavier bass, lighter treble, mirroring acoustic piano physics

Sound Engine and Polyphony

The Progressive Harmonic Imaging engine samples every key of two world-class concert grands individually. A 3-song internal recorder and 100-pattern drum rhythm section extend the instrument beyond a pure stage piano.

• Polyphony: 192 notes — sustains dense chord passages without note drop-out
• Piano sounds include SK-EX, EX, and K-60 — flagship concert grand plus traditional upright voicing
• 34 voices — electric pianos, drawbar organs, strings, choir, and bass
• Effects engine with 16 types plus amp simulator — chorus, tremolo, delay, and vintage amp profiles

Connectivity, Pedals, and Stage-Ready Practicality

Modern stage players need flexible I/O, and the ES520 delivers wireless and wired options in a 14.5 kg chassis.

• Bluetooth: Ver. 4.1 MIDI + Audio (aptX) — pairs with apps and streams audio cable-free
• USB to Host + USB to Device — MIDI communication plus load/save of registrations and SMF playback
• Pedal input for Damper — half-pedal support on the included F-10H; Soft and Sostenuto available via optional GFP-3 or F-302
• Audio I/O: Line In (3.5 mm), Line Out (L/MONO + R 6.35 mm) — integrates with mixers
• Dimensions of 1340 × 375 × 145 mm — slim profile fits the matching HM-5 stand

Who the Kawai ES520B Is Built For

The ES520 is the right choice for gigging keyboardists, church musicians, music teachers, and serious home players who want flagship-grade piano sound in a portable format. The 40 W on-board speaker system fills small-to-medium venues without external amplification. Bluetooth MIDI/Audio integration supports apps like PiaBookPlayer and PianoRemote, while 28 registration memories and 100 drum rhythms serve performers who switch sounds mid-set.

Kawai Heritage and the SK-EX Connection

Kawai has built acoustic pianos in Hamamatsu, Japan, since 1927. The flagship Shigeru Kawai SK-EX concert grand — hand-built by Master Piano Artisans at the Shigeru Kawai Piano Research Laboratory in Ryuyo — has been selected for prestigious competitions including the Chopin, Tchaikovsky, and Rubinstein events. The ES520 brings that heritage into the portable piano category, sampling every key of the SK-EX and EX instruments individually rather than stretching a single tone across the keyboard.
