About the Concentro S 503.2

The ELAC Concentro S 503.2 is a high-end bookshelf speaker that embodies the Concentro series' design and technology in a compact form. It features a unique organic cabinet shape with a fleeing baffle, trapezoidal base, and angled housing. Key technologies include the patented Crystal Membrane for midrange (aluminum-sandwich AS construction stiffening the cone to reduce resonances), AS-XR aluminum woofer with large 3-inch voice coil for powerful bass down to 34 Hz, and the JET 5c tweeter based on Air Motion Transformer for high sensitivity, dynamics, and extended response up to 50 kHz. It includes Directivity Control Rings (DCR) with three magnetic attachments (Neutral, Fokus, Spacious) to adjust mid/treble dispersion for room and listening position optimization. Available in black high gloss, white high gloss, and walnut gloss finishes. Recommended with LS 100 stands. Reviews praise its scale, detail, bass impact rivaling floorstanders, and mid/treble coherence despite needing power.
