About ELAC Concentro S507 Floorstanding Speakers, Pair
Concentro represents the pinnacle of craftsmanship, design, and sonic performance. The Concentro S 507 carries forward the full range of features and advantages found in the larger Concentro loudspeakers, while establishing its own distinctive visual identity.
MODERN HYBRID DESIGN
Progressive design elements from the Concentro Series merge seamlessly with the clean, elegant lines of the Vela Series to create a bold and contemporary aesthetic. The trapezoidal cabinet, convex baffle, and subtly angled enclosure come together in an organic, sculptural form that makes a powerful visual statement.
PATENTED TECHNOLOGY
An extensive array of patented innovations, including a newly developed woofer magnet system, ensures exceptional sonic performance. Effortless, room-filling sound can be precisely tuned to match your listening environment. Close your eyes, and you’ll forget you’re listening to a compact speaker—only the music remains.
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.
