The most prominent feature of the COTODAMA Speaker Box is Lyric Sync Technology, developed to display song lyrics in motion graphics for the first time in the world. The built-in engine automatically estimates the impression space of the lyrics and displays them with optimal motion graphics and fonts, presenting calming lyrics in soothing motion and uplifting melodies in dynamic movement. Sound quality was developed with world-class engineers to create the sensation of a singer performing in the room, with acoustics focused on musicality and pure voice. The Box model is designed as a 2-way bass reflex speaker capable of reproducing a wide range of sound, using a cabinet structure that minimizes excess distortion and vibration for clear and refined sound reproduction. Technical cooperation for the lyric technology was provided by the National Institute of Advanced Industrial Science and Technology.
