I have been involved in the research and development of all kinds of audio equipment, but I have yet to work on the research and development of high-performance, high-quality sound speakers. To the best of my knowledge, there is unfortunately no world-class high-performance, high-quality sound speaker manufacturer in Japan. Even though the measured characteristics such as frequency response and dynamic range are excellent, when you actually listen to music, the sound quality is very different from that of European speaker manufacturers.

As a research and development engineer, I took on the challenge of developing speakers with high sound quality that I could be satisfied with. As a result, I developed a completely new concept of a speaker box in which the sound quality is not affected by the materials used to construct the speaker box. Speaker developers around the world must think this is impossible. However, as a result of this challenge, an impossible CRSS speaker system was completed. The sound of the CRSS speaker heard for the first time was extremely low distortion and high sound quality, and the stereo image of the reproduced music was accurately reproduced.
