Description

The Gravis I and II subwoofers, the collection representing an ideal compromise between size and performance.

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.
