Harmony Blue Note Series

The Italian brand Harmony emerged in the 1980s alongside the first home speakers from the Italian high-end manufacturer ESB Audio. Production of car speakers began in the 1990s with a wide range of products that combined high sound quality with a significantly lower price than ESB Audio products. The main mission of the Harmony brand was to provide a high standard of sound quality with faithful reproduction of the entire sound spectrum, superior workmanship, all at a more affordable price. The same applies in 2023 when Zapco decided to create a new product line, Harmony. And why Blue Note? With this term, Zapco reminisces about the Blue Note Jazz era from 1930 to 1950. It is a way to connect the name of audio products with significant moments in modern music history. Harmony now returns to the market with a wide range of DSP amplifiers, which will expand in the future with more products to offer a complete line of audio equipment and meet the needs of all music enthusiasts.
