Defining the future of sound.

The Concentro is a true benchmark loudspeaker designed to commemorate 90 years of ELAC history and in response to calls for a loudspeaker that rivals—and surpasses—the most ambitious designs in the audiophile landscape today.

    • Features

      • Sophisticated aluminum woofers
        Through the use of aluminum, resonances that affect the linearity of common paper cones can be placed beyond the driver’s operating frequency range. The motor structure features a large 7.62cms diameter voice coil with oversized magnet and a vented pole piece to increase power handling, for accurate reproduction of bass frequencies that are clean, clear and powerful.
      • Crystal membrane midrange and mid-bass drivers
        The midrange/woofers of the Concentro employs the Crystal Membrane (patent pending) and the design is based on ELAC’s Aluminum-Sandwich AS Technology. The crystal-shaped inverse aluminum dome is joined to the paper cone in a special gluing process to result in the desired sandwich construction. Resembling the surface of a large crystal, the aluminum-foil stamping stiffens the aluminum dome, diminishing resonances and minimizing coloration, while improving power handling and dynamics.
      • JET 5 tweeter
        Delivering true high-definition sound, ELAC’s JET 5 tweeter enthralls with its lightning-fast response and wide dynamic range, offering minimal distortion, lots of headroom and a distinctly wider frequency range than conventional dome tweeters.
        The JET tweeter was developed on the basis of the famous Air Motion Transformer by loudspeaker pioneer Dr. Oskar Heil.
        The core of the JET tweeter is the folded foil membrane. With a fold width of only 0.84 mm, a major requirement in the JET production is precision. The JET 5 tweeter creates an effortless, airy and resonance-free image up to 50,000 Hz, and with its linear frequency response is ideally suited for the reproduction of hi-res formats.
      • Complex cabinet structure
        The sophisticated cabinet of Concentro eliminates standing waves and resonances, through sheer mass and the dense MDF material from which it is made, but because no parallel surfaces exist to excite such distortion. Additionally, midrange/tweeter, mid-bass and bass drivers are separated acoustically from one another with internal baffles that isolate the individual transducers while also helping to strength the enclosure.
      • Bi-wiring
        Two pairs of terminals that offer a convenient solution for bi-wiring or bi-amping the Concentro. These high-quality, gold-plated terminals are suitable for larger cable cross sections as well as for high-quality spade lugs. The quartet of posts is generously spaced and located on the flat portion of the Concentro base itself.
      • Custom base
        The base of the Concentro is a complex design machined from a single piece of aluminum that has a matt, clear-anodized -finish. Weighing more than 24.95 kgs, the base employs four adjustable, high-definition spikes for maximum stability and ideal coupling to hard or soft floor surfaces.
      • Power handling
        Anyone contemplating a pair of ELAC Concentro loudspeakers is likely to own power amplification commensurate with these state-of-the-art transducers. Even so, the Concentro presents a benign impedance load to most amplifiers, and has good sensitivity that allow it to reach impressive levels with even modestly powered amplifiers. However, high-current, amplifiers with output of at least 100 wpc are recommended to achieve realistic reproduction of uncompressed source material with wide dynamic range.
