The Klangdom of the ZKM | Institute for Music and Acoustics was finished in 2006 after three years of conception, planning and installation. Forty-three Meyersound speakers are attached to an elliptical rig system three-dimensionally in the room, four additional ones are placed on the ground. With this unique speaker instrument, as the head of the institute Ludger Brümmer explains, "complex polyphonic space-sound-movements can be displayed realistically and perceived from every spot in the room". This installation in conjunction with its expecially developed control software makes apperceptible the plasticity of sound in space, of which the musical avant-garde has been dreaming since the beginning of the last century.
A technical innovation is the combination of sound synthesis and spatialization. The room acoustics itself can be modeled. Brümmer: "The Klangdom is an instrument operated by the composer himself. It enables the composer to interact directly with the instrument making the assistence dispensable. In the Klangdom forty melodies can be concentrated to one point in the room or spread throughout the entire space. Now it is possible to connect sound synthesis processes directly to the spatial output spreading sound grain directly into space."
