Overview
Sonus faber Gravis VI – High-Performance Active Subwoofer
Extraordinary Depth. Unmistakable Italian Elegance.
Bass should do more than shake the room. It should bring music to life, reveal the scale of a performance, and deliver the visceral impact of a cinematic experience.
The Sonus faber Gravis VI is a high-performance active subwoofer designed to complement the world's finest loudspeaker systems. Combining dual 12.6-inch drivers, a powerful 1,700-watt Class AB amplifier, and a sophisticated sealed enclosure, Gravis VI delivers the authority and control demanded by reference-level music and home theater systems.
Designed to complement Sonus faber's Reference Collection, Gravis VI brings together exceptional acoustic engineering and the unmistakable craftsmanship of Italian luxury audio.
Dual Drivers. Serious Low-Frequency Authority.
At the heart of Gravis VI are two 320 mm (12.6-inch) long-throw drivers featuring sandwich honeycomb cones and wide rubber surrounds.
This dual-driver configuration is housed in a sealed enclosure engineered for controlled bass reproduction, making Gravis VI an exceptional partner for high-performance two-channel systems and demanding home theater installations.
From the subtle resonance of an acoustic bass to the explosive energy of a cinematic soundtrack, Gravis VI adds depth, scale, and impact to the listening experience.
1,700 Watts of Class AB Power
Gravis VI features a high-performance Class AB amplifier delivering 1,700 watts RMS and up to 2,400 watts of peak power.
This substantial amplification provides the power required to drive its dual long-throw woofers, delivering the dynamic capability necessary for demanding low-frequency passages.
Whether integrated into a reference stereo system or a sophisticated multichannel cinema, Gravis VI is designed to deliver powerful bass while preserving the musical character associated with Sonus faber.
Italian Craftsmanship That Deserves to Be Seen
Unlike conventional subwoofers designed to disappear into a corner, Gravis VI is crafted to become part of a beautifully designed listening environment.
An artisan-crafted wooden or lacquered top complements its minimalist cabinet, while Sonus faber's signature leather-wrapped sides add a luxurious finishing touch.
A selection of high-gloss finishes allows Gravis VI to coordinate with Sonus faber's Reference Collection and a wide range of sophisticated interiors.
Available finishes include Wenge High Gloss, Red High Gloss, Piano Black High Gloss, and additional decorative configurations featuring distinctive wood-grain patterns and an inlaid Sonus faber logo.
The Foundation of a Reference-Level System
A great subwoofer doesn't simply add more bass. It creates a foundation that allows the entire system to perform with greater scale and impact.
Gravis VI is designed for listeners who want substantial low-frequency performance without sacrificing the aesthetic refinement of their listening space.
Whether paired with Sonus faber loudspeakers in a dedicated two-channel system or incorporated into a luxury private cinema, Gravis VI provides the power, craftsmanship, and acoustic foundation for an extraordinary entertainment experience.
