The dream that inspires. The idea that turns it into reality. The passion for detail that creates something truly special: the ELAC Concentro S 509 is a piece of master craftsmanship, conceived to celebrate music with all senses.

The ELAC Concentro S 509: a loudspeaker with characterful design and an impressive feature set. The wraparound baffle forms the basis for magnificent acoustic performances. Combined with the gently angled cabinet, the trapezoid basic shape, and an expressive bottom assembly, complete with ‘high-heel’ effect, the result is a powerful yet natural and elegant appearance.

Innovative by tradition: the acoustic centerpiece of the Concentro S 509 is the stepX-JET – a concentric driver built around the new JET 5c tweeter and a midrange driver with an aluminum membrane. Its highlights are the exchangeable DCRs (Directivity Control Rings), which optimize the loudspeaker’s sound in the room by altering its directional characteristics in the mid-range frequencies.

Reassuring to know that everything has been thought of: from the four powerful woofers in an ICD configuration for defined bass reproduction devoid of unwanted mechanical vibrations to the high-quality design of the frequency crossovers and the luxurious cabinet finishes... the Concentro S 509 makes no compromises in technical terms but reveals a character of unbridled enthusiasm and a tangible love for music.


  • Elegant Design
    Its exterior is a perfect symbiosis of the extravagant design of the Concentro and the clean lines of the VELA Series. The trapezoid basic shape, wraparound baffle, and gently angled cabinet combine to convey a natural, low-key appearance. The striking bottom assembly achieves a ‘high-heel’ effect, imparting a sense of elegance and stability. Incidentally, it also guarantees an exceptionally sound footing.

  • stepX-JET
    The innovative stepX-JET features a concentric chassis built around a new JET 5c tweeter and a midrange driver with an aluminum membrane. A patented technology uses exchangeable DCRs (Directivity Control Ring) to tailor the directional characteristics in the mid-frequency range to conditions in the listening area. The different DCRs (three aluminum DCRs are included as standard) are used to influence the relationship between direct and diffuse sound in the listening area.

  • Side-Firing Long-Throw Woofers
    Four powerful side-firing long-throw woofers ensure effortless performance. The special ICD configuration (Impluse Compensated Design) guarantees contoured bass reproduction free of any coloration due to unwanted mechanical vibrations. Put simply, the Concentro S 507 will satisfy the most discerning listeners by reproducing audio signals to perfection across the entire frequency spectrum and at all volumes.
