- Feel Inspired
- A piano that will encourage enthusiastic players to become accomplished pianists, and transform living rooms into grand concert halls. This is the ambitious philosophy behind Kawai’s latest Concert Artist series – premium instruments that capture the essence of playing a magnificent concert grand piano, and inspire musicians to realise their true artistic potential.
TOUCH
- The Touch of a Grand Piano: Grand Feel III wooden key action
- Embracing many of the long-established principles associated with an acoustic piano, the Grand Feel III keyboard action utilised by the CA901 combines realistic materials, motion, and mechanism to recreate the exceptional touch of the finest concert grand pianos.
-
Long wooden key 
Counterweight 
Balance pins 
Weighted hammers
Let-off mechanism 
Triple sensor 
Ivory Touch key surface 
Ebony Touch key surfaceAll eighty-eight black and white keys are crafted entirely from long pieces of wood, with finely textured ivory and ebony-like surfaces applied to absorb moisture and assist control. Each wooden key pivots smoothly on a balance pin – the ends rising and falling to replicate the familiar ‘seesaw’ motion of an acoustic piano action. When pressed, the back of the key lifts, triggering a grade-weighted hammer to strike a pressure switch. The amount of force applied to this switch is then measured, and the corresponding note played with authentic tonal character and volume.
SOUND
- The Sound of a Grand Piano: Shigeru Kawai SK-EX
- Eponymously named after the company’s second president, the Shigeru Kawai range of luxury grand pianos were conceived as the next step in evolving the art of the piano. Each world-class instrument is hand-crafted by experienced piano artisans, using the finest available materials to ensure optimum touch, tone, and artistic expression.
Widely regarded as ‘the premier piano of Japan’, the flagship SK-EX grand piano graces the stages of concert halls and musical institutions around the globe, receiving universal acclaim for its tonal clarity and exceptional dynamic range. The magnificent tone of the SK-EX is at the heart of the CA901, with the latest model featuring two distinctive recreations of this peerless instrument.
- SK-EX Competition Grand
- The brand new SK-EX Competition Grand captures the sound of the latest generation SK-EX-L instruments, that in recent years have achieved success at the Chopin, Hamamatsu, and Sendai international piano competitions. This piano sound possesses a brilliant, clear tonal character, with a distinctive thick attack, and is specifically recorded from the pianist’s position.
- SK-EX Concert Grand
- The SK-EX Concert Grand captures the sound from an earlier SK-EX instrument, and is characterised by a warm, sensitive tone, and wide attack with rich reverberation. The tonal elegance of the SK-EX Concert Grand neatly complements the brilliance of the latest Competition Grand incarnation, allowing performers to enjoy the contrasting qualities of both sounds.
DELIVERY
- Premium audio technologies
- Developed by Kawai R&D’s highly experienced audio engineering team, the CA901 utilises specialist components designed for high-end audio reproduction. A high performance dual DAC system combines with the Concert Artist’s high specification power amplifiers to reproduce the Shigeru Kawai SK-EX sounds with stunning richness and clarity.
SPEAKER SYSTEM
- As the flagship model of the Concert Artist series, the CA901 features a powerful hybrid speaker configuration that combines premium driver units with Kawai’s highly-regarded soundboard speaker technology, delivering crystal clear treble frequencies and warm, resonant bass.
- Premium speaker drivers
- In addition to premium audio processing and amplification hardware, the CA901 also features a high specification speaker system, developed by audio specialists. Premium speaker drivers were selected for their flat frequency response and ultra-low distortion characteristics, ensuring the most accurate reproduction of the original Shigeru Kawai SK-EX grand piano, while diffuser panels help to disperse the sound more evenly.
- TwinDrive Soundboard Speaker System
- Complementing the premium quality drivers, the CA901 also incorporates the latest version of Kawai’s highly-regarded soundboard speaker system. This unique audio technology embraces the rich, harmonic qualities of wood by using transducers to channel sound energy onto a large soundboard, in order to produce a more natural, organic tone. Long wooden ribs securely attached to the soundboard further broaden the frequency range and volume of the resonating sound, resulting in a remarkably authentic playing experience that immerses the performer, and faithfully reproduces the tonal ambience of an acoustic piano.
FEATURES
- The Variety of a Digital Piano: Convenience & Flexibility
- Complementing the instrument’s class-leading Grand Feel III keyboard action and stunning SK-EX Rendering piano sound engine, the CA901 also offers a strong selection of digital features that further enhance one’s musical enjoyment.
Full Bluetooth® V5 connectivity and USB audio record/playback allows musicians to extend the functionality of their piano, or play-along with their favourite artists, while the convenient metronome and integrated lesson functions, featuring classical etudes and Alfred course books, ensure that regular practise is both productive and engaging for aspiring pianists.
- All functions are accessible from the CA901’s 5″ anti-glare touchscreen display, which allows sounds and settings to be selected from an attractive user interface simply by tapping or swiping the display with a finger.
The screen can also be set to fade out automatically while playing, thus preserving the instruments’ acoustic piano-like appearance, and minimising any visual distractions to the performer.
DESIGN
- Premium quality upright piano cabinet
- The latest Concert Artist instruments are housed within premium quality wooden cabinets, with tapered legs and rounded edge details contributing to the instruments’ light and modern character. As the flagship model of the series, the CA901 adopts a contemporary upright piano-inspired cabinet design, featuring a broad, simulated-leather lined music rest and Kawai’s Soft Fall closing mechanism.
- Cabinet finishes
- The CA901 is available in a choice of four attractive cabinet finishes: Premium Rosewood, Premium Satin Black, Premium Satin White, and luxurious Ebony Polish, allowing musicians to coordinate their piano with a range of modern interiors.
* For a visual representation of the piano in each finish, please refer to the Gallery function at the top of this page.
* Cabinet finish availability dependent on market location.
