Elac has consistently avoided the 90 degree angle: the fundamental shape of the Concentro S 507 is trapezoidal, with slopes on the bottom and top. To ensure the S 507 standing upright, the designer has given it "high heels", meaning it stands on raised feet at the back. The "stepX-JET" is another novelty: a concentric chassis consisting of the new "JET 5c" tweeter and a midrange driver with aluminum cone. With the interchangeable "Directivity Control Ring", the directional characteristic in the mid-range can be adapted to the individual conditions of the listening room. Three such aluminum rings are included upon delivery. The stepX-JET is supported by a bass-midrange speaker on the front. Four long-throw woofers arranged on the sides are responsible for the bass. The ported cabinet is a good 1.20 metres high and is available with a high-gloss black or white paint finish – now available for 5500 euros per unit.

The Concentro S 507 is the newest member of Elac's Concentro series. While being less "curvy" than the other models, it still features lots of unusual angles.
