Harmony Blue Note lineup
The Italian brand Harmony was born in the 1980s alongside the first home loudspeakers from the Italian hi‑end manufacturer ESB Audio. Automotive speaker production began in the 1990s with a broad range of products that combined high sound quality with significantly lower prices than ESB Audio products. This was Harmony’s main mission: to provide a high standard of sound quality with faithful reproduction across the entire audio spectrum, superior workmanship and all at a more accessible price. The same holds true in 2023, when Zapco decided to create a new Harmony product line. Why Blue Note? With this name Zapco pays tribute to the Blue Note jazz era of the 1930s to 1950s. It’s a way to link the names 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 additional products aimed at offering a complete audio lineup to meet the needs of all music enthusiasts.
