In the Yamaha SX Series grands, innovation comes in the form of Acoustic Resonance Enhancement (A.R.E.): treated rims and newly designed hammers. These expand the piano's tonal palette, giving added warmth and depth. The A.R.E. treatment imbues wood used in the rims with the acoustic properties of a beloved vintage instrument. In SX Series pianos, the effect is remarkable. You find yourself embraced in a richly expressive sound with a beautifully sustained resonance. Price includes trasnport and tunning.
