Sonus Faber Gravis I Powered Downfiring Subwoofer

BLAST FROM THE PAST

Sonus faber is not new to the arena of subwoofer design and engineering. The first subwoofer project, the Gravis FB100, was launched back in 1986, later followed Cremona M subwoofers. Today, with the new Gravis collection, Sonus faber returns to its roots, incorporating cutting-edge technology while maintaining its identity of natural sound and quality Italian hand-craftsmanship.

THE COMPLETION OF THE PINNACLE

Gravis I and II are the smaller subwoofers of the Gravis Collection.
These speakers have been designed to be easily integrated into every living environment and ideally matched with almost every kind of audio and audio/video system. In addition Gravis I and II are the perfect match for their loudspeaker siblings: the Sonus faber Sonetto Collection.

FEATURES

Gravis I and II deliver incredibly powerful performance from compact subwoofers.

Design

The connection with the Sonetto family is clear: From the leather top, soft to the touch and embellished by the hot branded Sonus faber logo, to the finishes; Matte, White, Piano Black, Wood, and Wenge.

Speaker Unit and Sound System

A 8" Ultra Long Throw down-firing speaker unit, along with a high current 150W Class AB Amplifier allowing it accurate and expressive bass reproduction well beyond its class.

The Rear Panel

Gravis I's rear panel features a complete connectivity solution that allows for both perfectly blended musical sub basss and powerful, percussive, home theater bass. A wide sound field reproduction is the result whenever this subwoofer unit is matched with a loudspeaker system. It's sound is rock-solid, fast and has startling depth.
