Piano string length known as speaking length
A very important part of piano scale design - longer string promotes richer and more powerful tone

Hailun HU122 - The longest bass string is 120cm. This promote better singing tone and powerful bass

Yamaha LU90 - The longest bass string is 110cm. This promote thin sound and weak in the bass
 

 


Action and Hammer
Underfelt is designed to provide an amount of compression outwards to keep the hammer in shape and ensure it rebounds when it hits the strings

Hailun HU122 - Full-sized Direct-Blow action type for better control and speed. All-wood action design and German/Japanese hammers with underfelt for durability and promotes better tone quality and power

Yamaha LU90 - Compressed-sized Direct-Blow action type and Japanese hammers with no underfelt. The parts of the action are smaller and meet greater angles and not optimized for good leverage. This results in more friction and wears as well as slow down the ability to repeat notes quickly as compare to the taller Yamaha models
 

 


Soundboard
Straight uniform grain contributes to greater stiffness and better tone amplification
