Concentro CBS 503.2

The Concentro S 503.2 is the bookshelf model in ELAC's Concentro 2.0 line, handcrafted in Kiel, Germany. It uses a VX-JET concentric high-frequency driver together with a 180 mm AS-XR crystal membrane woofer. The concentric layout aligns the acoustic centres of the drivers and controls dispersion, which is meant to give coherent imaging and a focused soundstage.

The JET 6 concentric driver combines ELAC's folded ribbon tweeter technology with an integrated midrange section. The crystal membrane geometry adds stiffness and helps control unwanted resonance. An Adjustable Directivity Control lets the speaker be tuned to the listening space, and the cabinet has a tapered, sculpted shape with a floating stance.

The speaker can be placed on a shelf or on the optional LS 100 stand. It is offered in Walnut, Black and White variants. The page gives no connection, impedance or sensitivity details; a factsheet in English and German is available for download from the maker.
