Concentro Floorstanding Speaker

The whole is greater than the sum of its parts. The ELAC Concentro demonstrates this convincingly. It is the ultimate ELAC loudspeaker in every respect.

At more than 5½–ft tall and weighing more than 300 lbs, Concentro commands attention. Its elliptical cabinet is crafted to the finest furniture-grade perfection and finished in high-gloss white or black epoxy, or to specification in any color in between.

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 today's audiophile landscape.

Meet Concentro

The Benchmark

Featuring smooth, stiff aluminum-sandwich diaphragms that fire in a push-push/pull-pull configuration, Concentro delivers maximum energy and accuracy down to the lowest octave. A complex base machined from a single block of aluminum and weighing more than 55 pounds supports integral oval side panels of precious wood, carbon fiber or leather surround a pair of side-firing 250mm woofers on either side of the enclosure.

Advanced Cabinet Design

Built for Performance

The sophisticated cabinet of Concentro eliminates standing waves and resonances, not just through its 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 strengthen the enclosure.

VX-Technology

Tailored to your listening space.

The acclaimed drive unit, which combines the renowned JET tweeter with a ring-radiator midrange driver in a concentric arrangement, provides the foundation of these speakers remarkable sound. What sets it apart is the variable X-JET suspension, hence the designation VX-JET. The thinking behind this drive unit draws from the fact that every room presents different acoustic characteristics and that the same loudspeaker will produce different results from one room to another. A mechanism on the rear of the loudspeaker allows for stepless adjustment of the entire drive unit by up to 8 mm in front of and behind the front baffle.

Crystal Membrane Driver

Engineered for Low Distortion

Based on ELAC’s Aluminum-Sandwich AS Technology. 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. The voice coil design of the drivers results in an expanded frequency range, and driver surround allows for longer cone excursions for truly prodigious volume and lowest distortion, a unique engineering achievement for a driver of its size.

JET 5 Tweeter

Lightning-Fast Response and Wide Dynamic Range

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 ELAC JET tweeter is one of the most legendary tweeters in the industry and has won international praise for its transparent and effortless sound image.
