M450

The M450 is a colossal concept as much as it is an unbelievable instrument. It’s the ultimate manifestation of David Klavins’ fearlessness in design and manufacturing. The world’s largest soundboard effortlessly sends crystalline highs, articulate midrange, and limitless bass throughout any space. But it’s not just the scale of the sound; the M450 achieves the same astonishing presence that only a KLAVINS piano can.
FEATURES
Soundboard
The M450’s soundboard, the world’s largest, offers unmatched resonance and tonal range. Crafted from hand-selected Bavarian mountain spruce in our unique cross laminated form.
Frame
Built with a high-grade steel frame, the M450 ensures exceptional durability, stability and strength – supporting its towering design with a lifespan surely measured in centuries.
Strings
To the very lowest note, the M450 has double bass strings, taking advantage of the string length and massive soundboard to create a depth of sound and raw power that is unparalleled.
Integration
The integratable M450i can be mounted inside walls, creating stunning architectural options. With a smaller layout footprint than a standard upright, the world’s tallest piano can also, counterintuitively, save space.
Self-Playing
Advanced recording and self-playing systems seamlessly blend tradition with modern technology allowing for simple enjoyment, or wild experimentation.
Customisation
Personalize your M450 with unique finishes, lighting, artwork, and body styles to match any space or architectural vision. Fundamentally, our concert grands can be built at any height.
A MONUMENT IN SOUND
While the size of the M450 is striking at first glance, it’s not designed to impress for its own sake. Its towering frame is essential to support a massive vertical soundboard – key to producing the lowest frequencies with clarity, depth, and power. The vertical soundboard delivers the sound of the piano more directly than any other concert grand in the world. It is the tallest piano ever built, the piano with the widest dynamic range in the world, and it features the largest soundboard in the entire history of stringed instruments.
All of these astounding claims fade the moment you hear it. Whether in a concert hall, recording studio, or private home, the M450 doesn’t just fill the space – it transforms it.
‘Just climbing the M450 is a special moment. I played the first notes. It was amazing.’
