Active subwoofer ESB Audio HR 6 US P

Active subwoofer ESB Audio HR 6 US P

ESB Audio presents the HR 6 US P active subwoofer from the Harmony series, which follows the popular HR 10 US model but offers significantly higher power, improved sound quality and smaller dimensions. Thanks to a Class D amplifier with 250 W RMS (up to 500 W peak) and a very low impedance of 0.45 Ohm, it delivers surprisingly strong and precise bass even in such a compact enclosure. Dimensions of only 220 × 190 × 76 mm allow easy installation under the seat of most vehicles. The subwoofer is equipped with both RCA and high-level inputs for simple connection to any audio system. The control panel allows adjustment of sensitivity, low-pass filter, bass boost and phase. Automatic power-on is standard and a wired remote control is included for convenient volume adjustment. The HR 6 US P is an ideal solution for those who want powerful, clean bass without sacrificing interior space.

Harmony series

The Italian brand Harmony was born in the 1980s alongside the first home speakers produced by the Italian hi‑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’s flagship products. That was Harmony’s main mission—to offer a high standard of sound quality with faithful reproduction across the audio spectrum, excellent craftsmanship, all at a more accessible price. The same approach continues today, when ESB Audio created the new Harmony Blue Note and Hard Rock product lines. Why Blue Note? With this term ESB Audio recalls the Blue Note jazz era from the 1930s to 1950s. It links the product names to important moments in modern music history. Products labeled "Blue Note" are characterized by high-quality, uncolored sound for uninterrupted listening across all genres. Within the Harmony series you will also find "Hard Rock" products with a different tuning, fuller and deeper bass and higher power. The Harmony series will gradually offer a wide range of products aimed at providing a complete line of audio devices to meet the needs of the broadest group of music enthusiasts. 

About ESB Audio

The history of ESB Audio dates back to 1972 when this Italian brand was officially founded. ESB Audio is among the most renowned loudspeaker manufacturers of the second half of the 20th century and over its rich history introduced many innovative technologies and high‑end home audio products that achieved huge global success. Based on their gained experience, ESB engineers began researching optimization of sound for automotive environments in 1984 and two years later started producing their first car speakers. Due to great success, ESB increasingly focused on the automotive industry and its demanding challenges. Car Audio became a phenomenon of the time and in 2005 a school dedicated exclusively to vehicle audio was established in Aprilia, where ESB is based. At that time the company also made the definitive decision to leave the home audio world and focus solely on vehicle sound. Today ESB, together with the American manufacturer of audiophile amplifiers and DSP processors Zapco, is part of the Italian Apex Group. The range includes several speaker series led by the super high‑end three‑way Diecimila system, which likely represents the finest and most expensive car speakers on today’s market. ESB’s main mission remains: to manufacture speakers of the highest quality focused on faithful sound that allows the user to experience reproduction as the artist intended—exactly according to the company slogan "Just like live".
