Modern engineering & traditional elegance in perfect harmony.
The superb Grand Feel II wooden-key keyboard action and stunning Shigeru Kawai SK-EX and SK-5 sounds, housed inside a traditional ‘K’ series polished ebony upright cabinet, complete with a real wooden soundboard speaker – the updated CS11 is the ultimate hybrid instrument for piano purists.
Reproducing the Concert Grand experience
A digital piano that will transform enthusiastic players into accomplished pianists, and modest rooms into grand concert halls. This is the ambitious philosophy behind Classic Series digital pianos – premium instruments that capture the essence of playing a magnificent concert grand piano, and inspire musicians to realise their true artistic potential.
The Touch of a Grand Piano: Grand Feel II wooden key action
Embracing many of the long-established principles associated with an acoustic piano, the Grand Feel II keyboard action utilised by the CS11 combines realistic materials, motion, and mechanism to recreate the exceptional touch of the finest concert grand pianos.
All 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.
The longest keys, the longest pivot length
In addition to having the longest keys of any digital piano, Grand Feel keyboard actions also boast the longest key pivot length – matching that of a Kawai grand piano.
This improvement ensures a more evenly balanced key touch weight from front to rear, and is particularly beneficial when playing complicated chords with fingers positioned towards the back of the keyboard.
88-key Graded Counterweights
In addition to grade-weighted hammers, the Grand Feel II keyboard action also features graded counterweights attached towards the front of all 88 keys.
As with an acoustic piano, these finely balanced weights help to lighten the touch of the keyboard during pianissimo passages, while adding a feel of greater substance when playing with force.
Triple sensor key detection
The Grand Feel II keyboard action also features an accurate triple-sensor key detection system for enhanced playing realism.
The added third sensor improves responsiveness when playing the same key repeatedly, and unlike conventional two sensor keyboard actions found in many digital pianos, allows the sound of a single note to be gradually ‘layered’ without the previous tone being lost.
In addition, Kawai’s action technology also monitors the speed at which each key is lifted, influencing the release character of piano sounds, and providing a greater range of expression between staccato and legato playing.
Ivory & Ebony Touch key surfaces
The handsome CS11 features Kawai’s highly regarded Ivory Touch white key surfaces as standard. This finely textured material gently absorbs fingertip perspiration and oils to assist playing control, and possesses a natural, matte finish that is smooth but not slippery.
To complement these premium white keys, Kawai has also developed Ebony Touch, an all-new black key material that reproduces the finely-textured grain and rich lustre of real ebony wood. The result is a keyboard surface that looks and feels as luxurious as some of the world’s finest grand pianos, inspiring musicians of all levels to become better pianists.
As the most authentic digital piano keyboard action, Grand Feel II even reproduces the ‘let-off’ characteristic of acoustic piano actions. This subtle ‘notch’ sensation can be felt when playing the keys of a grand piano very gently, and may be used by experienced pianists to aid control when playing pianissimo passages.
In addition, the Grand Feel II action supports playing notes from the let-off point (sometimes referred to as playing ‘off the jack’), allowing the most advanced piano techniques to be performed.
The Sound of a Grand Piano: Three world-class instruments
Earning a reputation as the ‘premier pianos of Japan’, Shigeru Kawai instruments grace the stages of concert halls and musical institutions throughout the world, and are prized for their outstanding tonal clarity and exceptional dynamic range.
The new Classic Series models capture the magnificent tone of two Shigeru Kawai instruments, the flagship SK-EX Concert and medium-sized SK-5 Studio grand pianos, allowing musicians to enjoy the contrasting properties of each.
In addition, the CS11 also features the distinctive sound of Kawai’s highly acclaimed EX concert grand piano, which has frequently been selected by professional pianists in such prestigious events as the Chopin, Tchaikovsky, and Rubinstein international piano competitions, among others.
All three instruments are faithfully reproduced with full 88-key sampling using the latest Harmonic Imaging™ sound technology, to establish a new standard in digital piano tonal quality.
Full 88-key stereo piano sampling
The rich sound of the SK-EX, SK-5, and EX grand pianos is at the heart of the CS11, with all eighty-eight keys of these world- class instruments painstakingly recorded, meticulously analysed, and accurately reproduced as high-fidelity digital waveforms.
Recording each key individually in this way – as opposed to stretching the same tone over several different notes – preserves the grand pianos’ unique harmonic character, and guarantees that the sound heard when playing any one of the CS11’s wooden keys is a faithful representation of the original acoustic source.
Harmonic Imaging technology
When playing a fine piano, the amount of pressure applied to the keyboard affects not only the volume of the sound produced, but also the unique tonal character of each note. Therefore, in order to construct a realistic acoustic portrait of each grand piano, not only is each key recorded individually, but also at a wide variety of different volumes, ranging from gentle pianissimo to thunderous fortissimo.
The CS11 offers a highly detailed acoustic portrait, with Harmonic Imaging XL technology ensuring smooth tonal transitions across the keyboard and throughout the entire dynamic range.
Extra Long sampling (HI-XL)
Taking full advantage of its expanded sample memory, the CS11’s Harmonic Imaging XL standard extends the important attack portion of the piano sound by up to 120%, articulating the natural detail and resonance characteristics of each note more clearly, and improving the instrument’s organic tonal quality.
