The high-end SX Series features luxurious, powerful sound that belies its size. Yamaha's unique Acoustic Resonance Enhancement technology and various innovations, such as newly designed hammers, work with traditional craftsmanship for greater tonal range and a sound with profound depth and warmth—stimulating the most demanding performers and responding to their refined artistry.
A new approach to achieving timeless resonance
Think of a Stradivarius, and you think of a rich, mellow tone that resonates more deeply with every passing year. What if you could bring that same timeless resonance to a concert piano? Yamaha discovered a way. Our A.R.E. (Acoustic Resonance Enhancement) treatment imbues wood used in the rims with the acoustic properties of a beloved vintage instrument. In our SX Series pianos, the effect is remarkable. You find yourself embraced in a richly expressive sound with a beautifully sustained resonance.
THE RIM
For the inner and outer rims of the SX Series, Yamaha craftsmen carefully selected wood based on its acoustic characteristics. During construction, they reduced the number of glue layers, using more than 30% thicker wooden materials than those of forerunner S Series pianos, to bring out the inherent resonance of that wood. This approach has shaped the acoustic character of the SX Series, adding richness, clarity, and muscle to the bass and mid-range, while maintaining a warm and inviting overall tone.
THE HAMMER
In order to realize the ideal sound, one of the most important factors is that the hammers must complement the piano body. The SX Series employs exclusive hammer felt made with a newly developed formula. Yamaha tested countless prototypes in the quest to find the perfect match for this piano. The superb elasticity of this hammer felt allows the player to achieve clear and beautiful tonal colors, along with well-balanced density across the full range from bass to treble. As a player, you’ll relish the artistic freedom and expressive nuance offered by the SX Series.
THE BACK BEAM
The huge forces exerted by a powerful fortissimo passage can cause a back frame to bend slightly and lose energy. To withstand such forces and efficiently turn them into richly resonant reverberations, a piano must have a strong back frame. Compared to the forerunner S Series pianos, the back frame beams on the SX Series are around 20% thicker. The extra support they provide results in a more rigid body and less unwanted vibration. The SX Series is built from the bottom up to provide a solid and stable foundation that supports authentic musicality.
THE SOUNDBOARD
Like a violin, a piano is a symphony of subtle curves. But the curve that arguably matters most in a piano is one you don’t often see—the convex section of the soundboard known as the crown. The crown’s job is to efficiently transmit the vibrations of the strings from the soundboard into the surrounding air.
Yamaha piano engineers call on generations of know-how and craftsman’s skill to construct soundboards that vibrate easily and achieve powerful projection. In creating the SX Series, Yamaha borrowed techniques used in the flagship CFX for attaching the soundboard, ribs, and bridge. The resulting soundboard assembly is carefully integrated into the piano body, where it delivers outstanding projection throughout any concert venue.
Made from specially selected strong European spruce, the SX Series soundboard is built to withstand stress and retain its shape. Throughout its playing life, it promises to deliver rich overtones, low decay, and a wide range of expressive tonal colors.
THE MUSIC WIRES
Hand-winding piano strings is an extremely demanding task that can only be performed by seasoned experts. As they wind pure copper around the core steel string, Yamaha craftsmen must delicately adjust the balance and tension of the strings. Those hand-winding piano strings are pliable and they bring overtones in better harmony with fundamental frequencies. What this means to your ears is a beautifully resonant sound with satisfying overtones.
THE DESIGN
The clean, modern design and graceful curves of the SX Series are the physical counterpart to its elegant and expressive sound. Taking the best from the forerunner S Series and augmenting it with practical innovations, the SX Series and augmenting it with practical innovations, the SX Series takes its place on the stage as a thoroughly contemporary piano.
