The LSX-70 and LSX-170 are members of the Relit series of Yamaha’s interior audio systems that bring speakers and lights together in a single unit. Audio and light are diffused together and projected in 360-degrees. The LSX-70 is rechargeable so you can take and use it anywhere you go.
The first concepts I was faced with in developing the new Relit series was where and how they would be used. While the LSX-700 reflected sound and light like an indirect lighting system, the inspiration to develop the LSX-70/170 came from lamps shining at the side of sofas, and candles glowing at the center of tables. My next thought was to make the light look beautiful. Using 3D graphics and mockups, I repeatedly conducted tests to decide what kind of light to project and from what direction toward the curvature of the bell-shaped diffuser, which spreads the sound around the surrounding area. I constructed many models to determine such factors as the pitch of the holes in the punching metal sheets through which light passes, the degree of light passage depending on the surface curvature, and the changes in moiré patterns of overlapping sections. I was also very particular about the sense of size and texture, and visited housing exhibition halls in Germany and Japan to investigate the sense of sizes and textures that are accepted in living spaces. I considered metallic and leather textural representation, a flawless finish from any angle, and placing buttons with discretion so as to prevent the LSX-70/170 from appearing like a household appliance, seeking to ensure that it would not look out of place even as a centerpiece. Although bending the punching metal sheets 360° was a challenge, it was achieved by multiple discussions with designers concerning how we could fit the metal sheets together so that there is no perception of front and back. In designing the startup sound, I requested the creation of a sound based on the sound of a stroke of a xylophone, envisaging the sound of the clashing of pieces of wood.
