Sonus Faber Gravis III

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, ten years later was born Sonus faber Cremona M. 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.

ALL-ROUND COLLECTION

Gravis collection, the active subwoofers line dedicated to the reproduction of low frequency, is able to match all Sonus faber full-range loudspeakers collections. Gravis III naturally fits in with Olympica Nova collection, while Gravis V and VI represent the perfect choice to those who want to complete Homage Tradition and Reference collections.

REFINEMENT AND ELEGANCE

The Gravis III, V and VI subwoofers, the most powerful and high-end models of the active systems line, have been designed to be the perfect complement to all the loudspeakers collections that marked the history of Sonus faber. Aesthetically connected by the body enriched by a black leather covering, they differ from each other by the finishes of the hand-finished wooden top.

in order to optimize the dynamic impact and the sonic reproduction depth.
