The Millennium III Upright Action

Sturdy Back Assembly for Stability

The revolutionary Millennium III Upright
Action features Kawai’s exclusiveABS-Carbon parts that are incrediblystrong and lightweight – properties thatallowed our engineers to optimize speed,
repetition, power and control. ABS-Carbon
parts are resistant to swelling and shrinking
due to climate, which helps the ST-1
maintain stable touch and tone over time
better than any comparable instrument.

With five powerful back posts, eachmeasuring 80mm by 80mm, the ST-1
back assembly stands alone amongits peers. Our laminated back post
construction offers maximum rigiditythat helps to provide enhanced tuning
stability over decades of rigorous use.

Longer 47” Music Rest

Longer Keys

The raised music rest with angled design
extends 47 inches across the upper panel,
making it the longest music rest on any
institutional piano. The added length
provides valuable space for books,
oversized scores and sheet music that
extends laterally.

ST-1 keysticks are longer than thoseon comparable pianos to provide moreconsistent touch response from the front
to the back of the playing surface for better
control and more accurate touch.

“Soft Fall” Fallboard Closing System

Reinforced Bench Design

The ultra-slow “Soft Fall” closing systemprotects hands and the piano’s finish fromthe harm that a jarring close might cause.

A stylish reinforcing panel adds tremendous
strength and years of useful life to the ST-1
bench, especially in institutional settings.

Other Essential ST-1 Features
Nose Bolts

The ST-1 is designed with two sturdy nose bolts that connect
the back posts to the cast iron plate for greater strength andtuning stability.

Microcell-Enhanced Repetition

Advanced microcellular foam material used for the hammer
rest cushion provides exceptional reliability of repetition andincreases the ST-1’s overall playing speed.

“Matched Strength” Plate Design

The cast iron plate is subjected to as much as 20 tons of stringtension. The proper combination of plate design, back post
structure and string tension provides enhanced tuning stability
for decades of reliable performance.

Tuning Pins

ST-1 tuning pins are 64 mm in length and manufactured
to rigid specifications with nickel-plated carbon steel.
Our precision thread-cutting process produces a pin withtremendous “reverse-grip” holding power.

Pinblock

The ST-1 pinblock is made from the finest North American
hard maple and spruce, cross-laminated in 13 plies to assurethat the tuning pins remain tightly fitted through a lifetimeof music-making.
