Discover the exciting blend of acoustic grandeur with the convenience and customisation of digital innovation. The Kawai K300 builds upon the success of its award-winning predecessor, the K3, that was named Acoustic Piano of The Year in four consecutive years and brings it firmly into the modern age.

Seamlessly switch between playing acoustically in all it's glory to then silently via headphones for situations where it's important not to disturb others (or have them disturb you). Thanks to the industry leading ATX4 silent system (taken from Kawai's own high-end digital pianos) the K300 ATX4 opens up new realms of musical possibility, any time of day!

The evolving sound engine, quality felt in silence SK-EX Rendering sound engine

When muted, ATX4 instruments utilise a high quality digital sound engine, which reproduces the sound of the internationally recognised Shigeru Kawai SK-EX concert grand piano.

This piano-specific SK-EX Rendering sound engine combines 88-key multi-channel sampling and advanced modelling technology to deliver the most realistic grand piano sound possible, with effects that allow pianists to simulate the reverb and ambience of performing in a concert hall. In addition, ATX4 instruments also include a selection of alternative piano sounds, including the EX full concert and SK-5 mid-sized grand, and a variety of other instruments such as church organ and strings.

Natural, acoustic piano touch, even when muted

As this is still an acoustic instrument at its heart, the ATX4 instruments incorporate Kawai'™s advanced IHSS technology, utilising contact-less optical sensors to accurately capture the subtle movements of the action hammers. This allows the full range of expression from delicate pianissimo to thunderous fortissimo to be performed with fluency, and for the natural touch of the piano to be maintained, even when the acoustic sound is muted.

Millennium III Upright Action

When played acoustically, the Millennium III Upright Action really comes into its own. Featuring components made of ABS-Carbon, a composite material created by the infusion of carbon fibre into our renowned ABS Styran. ABS-Carbon is incredibly sturdy and rigid, which allows the creation of action parts that are lighter without sacrificing strength. The result is a stronger, faster action that offers more power, better control and greater stability than conventional all-wood actions.

Die-Cast Aluminum Action Brackets

Made from a custom mold, die-cast parts are formed exactly the same every time. The K Series pianos feature three aluminum action brackets that are die-cast to provide an added measure of strength, uniformity and stability for accurate touch over time.

Extended Key Length

Longer keys make playing easier and provide more even response from the front to the back of the playing surface. The benefits to the player are greater control and more power with less effort.

Tapered Soundboard made of Solid Spruce

The soundboard is the heart of a piano. Its purpose is to transform the vibrations of the piano'™s strings into a rich, resounding tone. Kawai uses only straightgrained, quartersawn solid spruce for K Series soundboards. Each soundboard is strategically tapered to maximise its tone producing capability. Only those that meet or exceed our demanding quality standards are selected for use in our professional upright pianos.

Mahogany wood core & T-stapled, double felted hammers

Mahogany hammer mouldings are lightweight and extremely responsive. Found on only the finest pianos, mahogany is used for the hammer mouldings on the entire line of K Series Professional Upright Pianos. All K Series hammers are T-Stapled to preserve hammer shape and fitted with an added interior layer of underfelt to support the creation of exceptional tone.

Steel-Reinforced Keyslip

The piano'™s keyslip is the long, horizontal piece of wood that covers the front faces of the keys. Because it is long, thin and made of wood, a keyslip can warp or bend with changes in humidity, causing keys to stick. To eliminate this problem, a heavy-guage steel angle iron is added to prevent warping and bending in any direction. Keys move more freely with virtually no possibility of rubbing or sticking against the keyslip.

Keybed and Braces

The piano'™s keybed must be strong and stable to support the action assembly and maintain action regulation over years of heavy use. K Series keybeds are made with sturdy laminated hardwoods and reinforced by rear braces on the iron frame that help to ensure stable placement and add rigidity to prevent energy loss.
