Harmonic Design

Audio Effetti has selected Harmonic Design as a top brand specializing in the offering of high-tech products in the professional audio field.

Harmonic Design is a family-run German company, with over then forty years of innovation behind it, specialized in the development, production and sale of loudspeakers for numerous professional applications and areas of use.

Founded in 1980, with headquarters in Neckarwestheim, Germany, the company stands out for the quality and innovation of its products, addressing rental companies of professional PA systems, installers, service providers, musicians and all companies related to the world of pro-audio that require sound reinforcement systems of the highest quality.

Harmonic Design is committed to providing products that inspire and satisfy the needs of its customers. Total control over the production cycle allows it to offer a very high level of customization. Significant research and development areas have led to innovations such as the range of PA speakers with FRP (glass-fiber reinforced plastic) horns on all speakers, one of the first DSPs based on FIR filters for system linearization and environmental acoustic optimization and hd beamforming technology (which combines the advantages of Point Source emission with that of Line Source) for its column speakers, a step further than the simpler beam steering.

Harmonic Design loudspeakers are used in the sound reinforcement of airports, train stations, stadiums, convention centers, bars and restaurants, hotels and resorts, theme parks, shopping centers and shops, museums, theaters, places of worship, as well as corporate, conference and education environments.
