The CONCENTRO M 807 exemplifies a passion for form, function, and precision detail. Its striking three-dimensional baffle, with flowing contours and sweeping curves, draws the eye and guides it across the speaker’s elegant geometry. The cabinet, available in high-gloss black or white, is meticulously finished and accented with premium aluminum components, either die-cast or precisely milled from solid material. At the heart of the CONCENTRO M 807 lies ELAC’s pioneering VXe (Variable Coaxial Electric) technology. Designed to deliver unmatched clarity and spatial realism, VXe employs a circular array of six ultra-compact A-XR (Aluminum – eXtended Range) midrange drivers. Together, they form an acoustically ideal ring radiator, critical for rendering the nuances of musical space and precise sound localization.
