One look and you will realise that this is no ordinary speaker. Standing at more than 5.5 ft tall and weighing more than 130kg, ELAC’s 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 cannot be mistaken for any other speaker, with a complex base machined from a single block of aluminum and weighing more than 25kg. Integral oval side panels of precious wood, carbon fiber or leather surround a pair of side-firing 250 mm woofers on either side of the enclosure. These newly-developed units feature smooth, stiff aluminum-sandwich diaphragms, and fire in a push-push/pull-pull configuration that delivers maximum energy and accuracy, down to the lowest octave.
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 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 ELAC JET tweeter is one of the most legendary tweeters in the industry and has won international praise with its transparent and effortless sound image.
Superior build quality
Count the parts and look at them closely. These don’t look like the components that go in such competitively priced speakers, but rather, speakers that cost much more.
