The ”Uni-fi” in this speaker’s name comes from its unique driver arrangement. Using a design commonly associated with KEF, ELAC uses a concentric driver that places a 1” soft dome tweeter in the middle of a 4” midrange cone driver. This allows high and midrange sounds to reach your ears at exactly the same time, for a superior soundstage and imaging.

Known as the “audiophile's powered speakers,” the ARB51 Navis set utilizes high-end analog amplification in contrast to the lower-cost Class D amps more common in this form factor. These speakers use premium components while maintaining a minimalist footprint.
