The Italian brand Harmony was born in the 1980s with the first home speakers produced by the Italian hi-end manufacturer ESB Audio. The production of car speakers began in the 1990s with a wide range of products that combined high sound quality and a significantly lower price than in the case of ESB Audio products. And this was also the main mission of the Harmony brand - to provide a high standard of sound quality with faithful reproduction of the entire sound spectrum, above-standard processing and all this at a more affordable price. Harmony products have been and are associated with the phrase Blue Note, which refers to the Blue Note Jazz era (1930-1950). At ESB, they have found a way to connect the names of audio products with important moments in modern music history. Harmony products thus refer to the souls of people who are passionate about music and also to the famous names of that time. This is also Harmony's commitment to producing products with quality sound that will satisfy not only beginners but also more demanding listeners.
