Yamaha engineering developed a unique Extruded Aluminum Alloy Action Rail (bearing a Yamaha patent) that is one of the best innovations for improving a piano action in the last 100 years. This is one of the most valuable patented technology by Yamaha and V-PRO technology greatly increase the stability of tune and also withstand high tons of string tension. V-Pro plates are stronger and visually more appealing. Yamaha UX uses V-Pro (Vacuum Shield Mold Process) in casting the iron frame (plate). This is why UX piano can last longer compare to other normal series. Reinforcing the crown ensures that the tone quality will remain for years and years and improves tuning stability. Yamaha UX reinforces the crown in its soundboards by using ribs that continue to the edge of the soundboard, and are glued into the notched liner (or inner rim on the grand piano). Solid spruce, is the choice in all fine pianos for the best amplification of sound, best tone and stability. Specification, 131cm Tall (Tall is good)Īt the Yamaha lumber mill and wood processing facility, the finest spruce is quarter sawn and less than 20% of the total is chosen and reserved for Yamaha piano soundboards. However, since of the price of Japanese labor has made the UX series lessĬompetitive, the production was very small and it is very rare to find UX series in Malaysia used market as well.Ģ. With the excellent use of material and craftsmanship, for many years this was the top choice for practice and teaching studios across Asia, Europe and US. You can see clearly from the photo, the fallboard design is different from the U series. The front panel is vented to allow more sound from the front of the instrument. UX series pianos are manufactured in Japan, using higher grade materials than the standard U series. Made in Japan, Flagship upright series during 1980s This is to support the tension of the stringsīetter and thus enabling the piano to hold its tune longer and produces a deeper, richer sound than normal pianos.ġ. The usual construction of a piano is to have vertical support back post in its back, the UX has an “X” support. If you go to the back of a UX1 you will see something you may have never seen before.
