A Master Piano That Never Has to Fall Silent

The Kawai K-300 ATX4 in polished ebony with chrome fittings combines the full, round tone of a classic Kawai upright piano with the freedom to practise quietly through headphones at any time. As a further development of the multi-award-winning K-3, it is the first choice for ambitious pianists, families and music schools who value the highest sound quality and everyday flexibility.

Millennium III Action for Maximum Control

The wooden construction has been extended to 5 back posts and the cast-iron plate is joined to the frame even more firmly by additional plate support screws – the result is an even fuller and more rounded tone, reinforced by the solid spruce soundboard. The precise Millennium III action with mahogany hammer cores and a double felt underlay gives you control from the softest pianissimo to the most powerful forte.

ATX4: Silent Playing Without Compromise

The integrated ATX4 system measures every hammer movement without contact via high-resolution optical sensors (IHSS) and reproduces the sound of the legendary Shigeru Kawai SK-EX concert grand piano through headphones – including room resonance modelling for all 88 keys. Via Bluetooth or USB you connect the piano to the PianoRemote app and select voices, record your practice or access an extensive sheet music library.

Your benefits at a glance:

• Full concert tone: solid spruce soundboard and reinforced frame construction for round, carrying notes.
• Precise playing feel: Millennium III action with mahogany hammers for the finest touch sensitivity.
• Practise around the clock: ATX4 Silent system with SK-EX sampling for silent playing through headphones.
• Full connectivity: Bluetooth Audio/MIDI, USB and the PianoRemote app for sound settings and recording.
• Elegant looks: polished ebony cabinet with high-quality chrome fittings.
