The Gravis I and II subwoofers, the collection representing an ideal compromise between size and performance.
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.
Gravis I and II deliver incredibly powerful performance from compact subwoofers.
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.

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