Concentro S 503

Top class in miniature. For fans of monitor loudspeakers or where size is decisive, this loudspeaker is the ‘non plus ultra’. With the Concentro S 503 , ELAC achieves the almost impossible from a relatively small housing. Amazingly deep bass response in combination with the beautiful detail reproduction of the StepX-JET dual-concentric driver make this monitor loudspeaker superior.

StepX-JET dual-concentric driver

The newly developed StepX-JET dual-concentric driver with integrated JET5c ribbon tweeter by ELAC is the most eye-catching. With the patented DRC (Directivity Control Ring) technology, the ratio between direct and diffused sound can be adjusted to the acoustic environment and the listening position by means of three supplied, differently shaped, magnetic attachments.

18 cm woofer for deepest bass

The XR (eXtended Range) bass driver with AS (Aluminium Sandwich) with crystal cone offers bass reproduction down to 34Hz. Even much larger floorstanding loudspeakers can bite into that.

Compact beauty

With the S 503 , ELAC proves once again that building compact loudspeakers is a specialty of the house. The fact that this is also possible at a high-end level will be welcomed by the right-minded audiophile, who also makes demands on the impact on the interior. A jewel for the living room in terms of sound image and as an object.

Concentro Series

In the Concentro series, all – partly patented – technology from ELAC has been used to design absolute high-end loudspeakers.
