Hard Rock Series

Hard Rock — subwoofers and speaker systems engineered to move air and people.

The Harmony brand was launched in the 1980s, together with the first home loudspeakers produced by ESB. The production of Harmony car speakers began in the 90s, with a wide range of products that combined high quality performance at a lower price than the ESB speakers themselves, yet without ever forgetting the final goal: a high-fidelity speaker capable of reproducing the entire sound spectrum.

ESB now expands its product range with the Hard Rock (HR) Series, offering all you need in convenient ready-to-use speaker systems, including active subwoofers that can be easily installed under the front seats or that fit inside the rim of your spare wheel. The HR Series includes 4", 5", and 6.5" 2-way component systems and coaxials, all designed to be easily installed in a vehicle’s original speaker housings and to integrate with a factory head unit or an aftermarket amplifier. The woofer’s pressed paper cone, large aluminum voice coils for high power handling, and silk dome tweeters with neodymium magnets are just some of the features that make these speakers uncompromising.
