Yamaha S5X Premium Acoustic Grand Piano - 6'7" Polished Ebony

A Soundboard That Earns Its Crown
SX Series soundboards share the same DNA as our world-renowned flagship CFX. The soundboards and ribs are crafted from hand selected European Spruce to deliver warm overtones and a wide range of colors.

Matured to Perfection
A patented wood maturation process we call A.R.E. (Acoustic Resonance Enhancement) allows our craftsmen to precisely control the moisture content in the hand-selected wooden rims of every SX Series piano. The result is a warm, intimate tone with the sustained resonance comparable to a vintage instrument.

A Powerful, Natural Resonance
The back posts have been thickened to give SX Series pianos a robust backbone to project the most powerful fortissimo while maintaining its rich, resonant sound. A time-honored assembly process decreases the use of glue on the inner and outer rims so nothing gets in the way of the natural vibrations of the wood.

A More Expressive Hammer
Yamaha craftsmen spent years shaping the finest materials into a hammer that helps create warm, powerful tones with a full range of beautiful, subtle colors.

Hand Wound Bass Strings
Our artisans painstakingly wind pure copper by hand to adjust the balance and tension of every bass string in this superb instrument. You can hear the attention to detail in every note.

Voice-Regulated and Tuned by Master Technicians
Each SX Series piano is meticulously voiced, regulated and tuned in our Concert Piano Workshop to bring out the nuanced colors, harmonics and resonance from these superb instruments.

Advanced V-Pro Frame
Yamaha was the first company to use an advanced Vacuum Shield Mold casting technology called V-Pro to create a stronger, lighter, more durable frame worthy of the grandest grand piano. Every SX Series frame is built to our exacting specifications at our Iwata Forge in Japan.
