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, ten years later was born Sonus faber Cremona M and more recently, in 2014, the Sumiko Subwoofers S Series. Today, with the new Gravis Collection, Sonus faber returns to its roots, merging a ever increasing cutting-edge technology while maintaining its identity of natural sound and quality Italian hand-craftsmanship.

The Gravis V and VI are the most powerful active subwoofers Sonus faber has ever designed
in order to optimize the dynamic impact and the sonic reproduction depth.
