The ELAC Concentro S 509 is a distinctively styled loudspeaker, which, at first glance suggests a close resemblance to the smaller Concentro S 507, a direct comparison reveals the major differences.

The shape of the Concentro S 509 seamlessly blends the extravagant design of the large Concentros with the clean lines of the Vela Series. The wraparound baffle is combined with the gently angled cabinet, the trapezoid basic shape and expressive bottom assembly with a “high-heel” effect to create a “powerful yet natural and elegant appearance”. The overall dimensions create a canvass for high-gloss lacquer and elegant real wood veneer finishes.

Drivers

The acoustic centerpiece of the Concentro S 509 is the stepX-JET: a concentric chassis comprising the new JET 5c tweeter and a midrange driver with an aluminum membrane. Patented technology uses exchangeable DRCs (Directivity Control Rings) to tailor the directional characteristics in the mid-frequency range to conditions in the listening room. The different DCRs (three aluminum DCRs are included as standard) are used to optimize the relationship between direct and diffuse sound in the listening zone.

The stepX-JET is supported by a front-mounted low/midrange unit that employs AS-XR technology. Four powerful side-firing, long-throw woofers with a diameter of 180 mm ensure bass performance. The special ICD configuration (Impulse Compensated Design) gives bass reproduction free of any coloration due to unwanted mechanical vibrations.

Price And Availability

The Concentro S 509 is available in high-gloss lacquer finishes (black and white) now at a suggested retail price of 16000€ per pair, and, by the end of June, in high gloss walnut veneer at 17000€
