ELAC Navis ARB-51 powered bookshelf

ELAC’s new Navis Series answers every minimalist audiophile’s dream of a no-compromise powered speaker driven by best-inclass amplifiers that are truly deserving of the name “high end.” While most powered speakers rely on Class D digital designs, ELAC engineers build in 300 watts of pure analog amplification— for maximum power and exceptional sound. Add the Discovery Connect wireless transmitter to your system, and Navis becomes a wireless speaker that lets you enjoy streaming content without a cable in sight.

Sonic excellence with ELAC’s state-of-the-art drivers

Designed from the ground up, the full-range, monitor-quality Navis Bookshelf features ELAC concentric-driver technology to deliver unsurpassed mid- and high-frequency performance, coupled with a custom aluminum woofer for truly impressive bass, all in one compact, elegant package. Each of the three transducers is powered by its own dedicated analog amplifier, with a selection of RCA or XLR balanced inputs.

EISA Award Best Active Stereo Loudspeaker 2019-2020

Part of a new, two-strong active speaker range from ELAC – there’s also the larger floorstanding ARF-51 – this bookshelf design combines custom drivers and an analogue crossover design all perfectly integrated with inbuilt amplification to give a sound of remarkable precision and clarity. By dedicating one amplifier to each driver – the tweeter and midrange are mounted concentrically for enhanced focus – ELAC ensures each is driven to the best of its capabilities. Connect the speakers to a preamplifier via RCA or XLR cables, and you have a complete, optimised system. You can even connect the speakers wirelessly using a choice of ELAC AirX2 hubs. Brilliant!

NAVIS ARB-51 Features:

ELAC NAVIS Series Speakers - Powerful Trifecta

Powerful Trifecta

Inside each Navis Bookshelf Loudspeaker is a Tri-Amp Pure Analog Amplifier, employing three separate amps for each transducer: a 160-watt BASH AB amplifier for the woofer, a 100-watt BASH AB amplifier for the midrange, and a 40-watt Class AB amplifier for the tweeter. A total amplifier power of 300 watts ensures that each transducer is optimally—and amply—powered, eliminating clipping and crossover distortion, and driving each transducer with authority. Specs like a 110 dBA signal-to-noise ratio and 100 uV noise floor could only come from such audiophile-quality amps!
