Since its founding in 1980, Harmonic Design has stood for research, development and production of innovative loudspeaker systems and acoustic services. We thought early in systems and established the use of system controllers (then still analogous) as early as 1988. The MLSSA measuring system took computer-aided speaker development to a new level in the early ’90s. This was followed in 1994 by the first digital signal processor with pioneering filter options. In recent years, we have developped technologies such as the GroupDelayCorrection or the PowerSound algorithm.
The Harmonic Design Philosophy
The holistic system consisting of loudspeaker box, digital system controller and amplifier represents our understanding of a future-oriented system. The individual components are individually optimized and unfold their full potential in combination as a system: The sound pattern is faithful, the power is exceptional and the handling is simple.
