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.

Sonus faber Gravis V and VI, the most powerful models, have a speaker unit with a long stroke 12” design with a highly efficient Class AB amplifier rated at 850W into an 8 ohm load for the Gravis V and 1800W into 4 ohm for the Gravis VI. This huge energy reserve is responsible for a fast response and a wide frequency range.

Through the use of a dedicated app the user can choose among 4 presets, or even modify the cutoff frequency and the acoustical output phase for seamless integration with the main loudspeakers. Delay, parametric filters and limiters are also available for the most accurate sonic performance calibration.

Sonus faber Gravis V and VI have been studied as the perfect complement to the Homage Tradition and Reference collections. From an aesthetic point of view, they have the same refined and clean design: the top is a hand-finished wood element that creates the connection with their loudspeaker siblings and features the three unmistakable Sonus faber finishes: the elegant Wengè, the iconic Red, and the essential Piano Black.


The Gravis V and VI subwoofers, the most powerful and high-end models, have been designed to be a perfect complement to the Homage Tradition and Reference collections. The project's goal is to satisfy the need for a powered subwoofer to match the excellent performances of those loudspeakers ranges.
