Kawai K-300 ATX4 – the sound of a real piano, even in silence

With the Kawai K-300 ATX4, you bring home an upper-mid-range acoustic upright that combines the full, natural voice of a real piano with the freedom to practise silently through headphones whenever you like. Whether you are preparing for conservatory auditions, an ambitious hobby player, or looking for a piano the whole family can enjoy, the K-300 ATX4 gives you an instrument built to last for years of playing.

Millennium III action and a solid soundboard

At the heart of the instrument is the Millennium III action, made from high-strength ABS-Carbon: it responds with exceptional speed and precision to every keystroke, from the softest pianissimo to the most powerful forte. The solid, tapered spruce soundboard (1.39 m², 11 ribs) delivers a full, rounded tone that fills the room. The back frame, extended to 5 back posts, together with the reinforced cast-iron plate connection, adds further tonal stability.

AnyTime silent system: practise quietly whenever you want

The ATX4 silent system turns your K-300 into a private practice instrument at the touch of a button: the hammers are mechanically held back from the strings, and playing is heard through the included Kawai SH-9 headphones. Everything is controlled conveniently via the Kawai PianoRemote app (iOS/Android) over Bluetooth, including a choice of 90 sounds, a metronome, record/playback, and built-in Lesson exercises.

Your benefits at a glance:

• Full, rounded tone: solid spruce soundboard and reinforced frame for a rich, carrying sound.
• Precise playability: the Millennium III action captures the finest touch nuances.
• Silent practice on demand: the AnyTime system with headphones, without disturbing anyone.
• Digital practice tools: app control, metronome, recording and Lesson exercises in one instrument.
• Built to last: mahogany hammer cores with underfelt and double castors for everyday use.
