Concentro 2.0 Floorstanding Speaker
The Concentro 2.0 cannot be mistaken for any other speaker, featuring a complex base machined from a single block of aluminum and weighing more than 55 pounds.
The aluminium sandwich woofers in a push-push/pull-pull arrangement are characterized by high internal damping (cardboard cone) and high torsional rigidity (aluminium dome) and deliver an enormous but controlled bass down to the deepest subsonic range. Oval side panels made of solid wood, laminated with carbon fiber or leather, frame two side-firing 250 mm woofers on each side of the cabinet.
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 3-inch 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 eye-catching surface of the crystal membrane is more than just an attractive design feature. 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 6 tweeter
Lightning-Fast Response and Wide Dynamic Range
Delivering true high-definition sound, ELAC’s JET 6 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.
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 55 lbs, the base employs four adjustable, high-definition spikes for maximum stability and ideal coupling to hard or soft floor surfaces.
