Description
The Sonus faber Gravis II is a compact, musically expressive subwoofer that brings depth, weight, and emotional realism to high‑performance audio systems—without compromising elegance or control.
Designed for discerning listeners and refined living spaces, the Gravis II delivers tight, articulate low frequencies that enhance music and film soundtracks alike. Rather than overwhelming the room, it adds foundation and scale with precision, allowing bass lines, percussion, and cinematic effects to feel natural, textured, and seamlessly integrated with your main speakers.
A high‑excursion driver driven by a powerful, well‑controlled amplifier enables the Gravis II to respond quickly and accurately to dynamic changes, from subtle acoustic nuances to impactful low‑frequency moments. Flexible tuning options make it easy to match a wide range of speakers and room sizes, ensuring a coherent, balanced presentation.
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.
