Sonus faber Gravis I & II

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.


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

Speaker Unit & Sound System Gravis I

An 8" Ultra Long Throw down-firing speaker unit, along with a high current 150W Class AB amplifier allow Gravis I accurate and expressive bass reproduction well beyond its class.

Speaker Unit & Sound System Gravis II

Gravis II features a 10" Ultra Long Throw down-firing speaker unit and a front-firing 10" aluminum alloy diaphragm passive infra-bass radiator, along with a high-current 400W Class AB amplifier.
