The K-300J builds upon the success of its award-winning predecessor, the K-3, named Acoustic Piano of the Year in four consecutive years. The K-300J proudly extends this distinguished legacy.
K Series DEMO
The revolutionary Millennium III upright action is the secret behind the ultra-responsive touch of the K Series upright pianos. Introduced in 2006, the Millennium III upright action features 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.
ABS Carbon is many times stronger than wood and is virtually impervious to shrinking and swelling due to humidity. This extraordinary combination of strength and stability allows ABS Carbon action parts to transfer energy to the hammers with unparalleled efficiency, power, precision and nuance for a superb playing experience.
|One of the most coveted attributes of a fine piano is dynamic range – the ability to play not only thundering fortissimos, but also the most delicate and sensitive pianissimos. Longer keys make playing easier and provide a more even response from the front to the back of the playing surface, benefitting the player with greater control and more power with less effort.
Our exclusive NEOTEX key surface material made with cellulose fibre offers the smooth, understated texture of natural ivory and ebony – and a semi-porous, silica-filled surface to absorb the hand’s natural oils and perspiration that can cause slipping. NEOTEX resists cracking and fading over years of use, and is used for both the sharps and the naturals for a consistent feel across the entire keyboard.
|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 straight-grained, quarter-sawn solid spruce for K Series soundboards. Each soundboard is strategically tapered to maximize its tone producing capability. Only those that meet or exceed our demanding quality standards are selected for use in our professional upright pianos.|
|The piano’s soundboard is placed under tension to create a slight curvature – or crown – that dramatically increases the production of sound. K Series pianos feature full-length ribs that are securely notched into the rim liner on all sides to preserve the soundboard crown over time. The ribs also distribute sound energy more evenly across the soundboard to optimise its tone-producing capabilities. Contour bars reshape the speaking area of the soundboard to resemble the contour of a grand piano soundboard, while reflecting sound energy back into the centre for increased tonal power and sustain.
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. Bridges transfer the vibrations of the strings to the soundboard. K Series bridges are made from select hard maple, individually notched for a clear, powerful tone quality. Height is carefully set and matched to the iron plate for correct string pressure and optimal tonal transfer.
|The strength of a well-crafted instrument makes the piano one of the most impressive examples of technology, engineering and craftsmanship in the world today. K series professional upright pianos are designed with tremendous strength to ensure stability of tone and touch over time. On all K Series models, the soundboard is supported by exceptionally strong multi-layered back posts and our proprietary “matched strength” iron plate. Using state-of-the-art CAD technology, we calibrate the strength and mass of the plate to match the scale design of each individual model, while plate bolts strengthen the connection between the plate and back posts for greater stability.|
|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. Furthermore, the keyslip – the long, horizontal piece of wood that covers the front faces of the keys – is reinforced with a heavy-gauge steel angle iron to prevent warping or bending in any direction.
The multi-grip pinblock on all K Series pianos is multi-laminated with a minimum of eleven cross-banded layers of North American hard maple for maximum strength and consistent torque, and K Series tuning pins are made from the finest steel, machine-threaded for maximum bi-directional torque and nickel plated to enhance beauty and provide long-term protection.
|The K Series pianos feature sleek lines and delicate accents that convey a striking, stately presence. Combining elegant form with rich, vibrant textures of tone, they will surely enhance the cultural ambience of any room.|
|As functional as they are beautiful, K Series upright pianos include a long list of inspired features designed to ensure effortless practicality. The ultra-slow “Soft Fall” closing system protects hands and the piano’s finish from the harm that a jarring close might cause. Conveniently built into the fallboard, selected K Series music racks extend 100cm to accommodate multiple music books or sheet music that extends laterally.
Our proprietary casting process binds molten brass to a sturdy steel core resulting in strong, beautiful pedals that will not wear through over time. Similarly, K Series front casters made of solid brass are as sturdy as they are attractive, with double casters used for the larger K Series models (from K-300).
The height adjustable bench on all K Series models is especially valuable for teaching studios with many students and for families with more than one player.
