This pair of Navis ARB-51 Powered Bookshelf Speakers from ELAC can output up to 300W of power through three class-AB amplifiers. Each bookshelf speaker features a 1" soft-dome tweeter that's concentrically mounted to a 4" aluminum midrange driver, and a 5.25" aluminum woofer. The ARB-51 delivers a frequency response of 44 Hz to 28 kHz to reproduce a wide range of frequencies. You can adjust Low, Mid, and High Frequency EQ settings, High Pass Filter, and Gain settings. Each speaker features an RCA and an XLR input, along with an AirX2 wireless interface, which is used with the ELAC Discovery Connect (sold separately) to stream Discovery, Spotify Connect, Bluetooth, AirPlay, and Roon services (services also available separately).
The speaker features an in-house-developed 4" aluminum midrange driver with a concentrically mounted 1" soft-dome tweeter.
Custom Designed Woofer
The proprietary woofer features a 5.25" aluminum cone, designed to deliver slam, punch, and accurate low-frequency sounds.
Inside each Navis bookshelf loudspeaker is a Tri-Amp Pure Analog Amplifier, employing three separate amps for each transducer: a 160W BASH AB amplifier for the woofer, a 100W BASH AB amplifier for the midrange, and a 40W Class AB amplifier for the tweeter. A total amplifier power of 300W 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 are achievable thanks to the amplifiers used.
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. The wireless function can be turned off for a no-compromise analog input and output.
