Sublime sound served up with serious power

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.

Navis series powered loudspeaker features:


One reason the Navis sounds so natural is because of its in-house developed transducer, a 4-inch aluminum midrange driver with a concentrically mounted 1-inch soft-dome tweeter. Combined, this signature configuration lets Navis set the performance standard for its class.


Navis’s single woofer reproduces bass with authority, thanks to the special design of its driver. Developed in-house, the 5¼-inch aluminum cone is the ideal structural material, speci-fied for its ability to deliver slam, punch and accurate low-frequency fundamentals.


Navis’s elegant design integrates perfectly with any interior. Its enclosure has a fine-furniture finish, available in Gloss Black, Gloss White and Wood Veneer. A dedicated floor stand completes the installation, and is recommended for optimum performance.


Inside each Navis Loudspeaker is a Tri-Amp Pure Analog Amplifier, employing three separate amps for each transducer: a 160-watt BASH AB ampli-fier 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!


Local inputs include balanced XLR, RCA and Wireless, when used with ELAC’s Discovery Connect wireless transmitter to stream Discovery, Spotify Connect, Bluetooth, AirPlay and Roon. Just switch Wireless “Off” for a no-compromise analog input and output.
