ELAC Concentro S 507 Floorstanding Single Speaker (Black High Gloss)

The ELAC 507-GB is a single floorstanding speaker from the Concentro S series, designed for listeners who expect true full range performance and refined style in one cabinet. It serves equally well as the centerpiece of a high-end stereo system or as the front channel in a reference home theater setup.

This speaker follows a four-way architecture that pairs ELAC’s JET 5 folded ribbon tweeter with a 5.1 inch driver assigned to the high-midrange, a 7.1 inch driver that handles the low-midrange, and four 5.9 inch woofers that fire to the sides. The result is seamless integration from shimmering highs down to articulate, room-filling bass without audible gaps in the spectrum.

ELAC’s stepX-JET technology lets you fine-tune horizontal dispersion by swapping the included acoustic adapters, so the treble energy matches your room’s layout and seating positions. Meanwhile, the Impulse Compensated Design places opposing woofers on each side of the cabinet to cancel mechanical forces, reducing distortion and keeping the bass tight even at high listening levels.

A frequency range that stretches from 24 hertz to 50 kilohertz and power handling up to 500 watts allow the Concentro S 507 to partner with a broad selection of amplifiers, from refined tube designs to high-current solid-state models. With 88 decibels of sensitivity, it delivers impressive dynamics in medium or large rooms without demanding extreme amplifier gain.

The cabinet wears a deep black high-gloss finish that complements modern interiors, and the included spikes anchor the enclosure on carpet or hardwood for improved clarity. Whether you cue up delicate acoustic tracks late at night or host a movie marathon at reference volume, the Concentro S 507 stays composed and engaging, revealing the nuances that make every recording unique.
