Kawai electronic products are always evolving. The ES4 portable digital piano was another step in that evolution that introduced a unique speaker enclosure design with 6 stereo speakers facing upward from the panel (3 per side) to provide maximum “tonal presence” for the player. The ES4 utilized Kawai’s critically-acclaimed Harmonic Imaging sound technology and the new Advanced Hammer Action AHA-IV design with AR Technology and graded hammers to create a class-leading combination of authentic tone and responsive touch. With 21 sounds, 96-note polyphony, Dual and Split functions and a 26-watt speaker system, it was an outstanding instrument for any musician who needed high performance in a portable package. The ES4 became a Kawai Legacy Product with the arrival of the its successor, the ES6. Visit our ES Series page to see the latest generation of ES Series instruments.
