Yamaha S6X – Premium 7′ Grand Piano Overview
Welcome to Popplers Music. My name is Josh. Let’s talk pianos.
Today, we are going to be taking a look at Yamaha’s S6X grand piano. The SX series are made with modern 21st century engineering and design. From 1990 to 2010, Yamaha went through a research and development process with the goal of making the best concert grand piano in the world.

Yamaha took everything they learned from creating their flagship CFX concert grand piano and crafted the SX series that are perfectly suited for the conservatory, recital hall, and intimate home settings.
SX series are almost entirely handcrafted and feature Yamaha’s acoustic resonance enhancement process, which precisely controls the aging of wood in the rims for a warm elegant tone. A completely redefined hammer helps produce a wide palette of colors, which create an intimate tone and depth of sound that is rarely found in grand pianos.
Here are some features found on the SX series.
SX series soundboards share the same DNA as Yamaha’s world-renowned flagship CFX. The soundboards and ribs are crafted from hand-selected European spruce to deliver warm overtones in a wide range of colors. A patented wood maturing process Yamaha calls acoustic resonance enhancement allows Yamaha craftsmen to precisely control the moisture content in the hand-selected wood rims of every SX series piano. The result is a warm, intimate tone, with a sustained resonance comparable to a vintage instrument.

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.

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. Yamaha 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.

Each SX series piano is meticulously voiced, regulated, and tuned in Yamaha’s concert piano workshop to bring out the nuanced colors, harmonics, and resonance from these superb instruments.
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 Yamaha’s exacting specifications at their Iwata Forge in Japan. Yamaha designed the SX series with graceful curves that are as elegant and expressive as its unmistakable tone.
