Product Highlight: 
The Yamaha UX300 is part of Yamaha’s X series. Yamaha claims that the X frame on the back makes the piano more structurally stable than those without.Also, the quality of materials used in the X models tends to be higher than the standard models. They have longer bass strings than the standard models too, allowing the pianos to generate a rich, high-quality tone, and they have vents in the front panel which can produce a more direct sound.
