SX GRAND PIANO SERIES
We took everything we learned from our flagship CF concert grand and created the perfect instrument for conservatories, recital halls and intimate stages.
The SX Yamaha Grand Pianos Series are almost entirely handcrafted and feature our patented Acoustic Resonance Enhancement process for precise control over the wood’s aging, providing the warmest and most elegant tone possible. Coupled with completely redesigned hammers, the SX produces a wide color palette with an intimate depth of sound rarely found in a concert grand.
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. 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. 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.
