1. Introduction to the Sonus faber Gravis I
The Sonus faber Gravis I represents the ideal entry point into the world of high-end low-frequency reinforcement. While many subwoofers prioritize raw volume over musicality, the Gravis I is engineered to be an extension of your main speakers. It provides the necessary “heft” and atmospheric depth that standard bookshelf and floorstanding speakers often miss.
Designed in Italy, the Sonus faber Gravis I is the smallest member of the Gravis family, but it carries the same DNA as its larger siblings. It is specifically tuned to complement the Sonetto and Lumina series, ensuring a “fast” bass response that keeps up with the most intricate musical passages.
2. Italian Elegance: Aesthetics and Build Quality
Most subwoofers are black boxes hidden in a corner. The Sonus faber Gravis I is different. It features a top surface hand-wrapped in premium natural leather, reflecting the sophisticated design language of Sonus faber’s most famous loudspeakers.
The cabinet is finished in elegant matte or wood veneers, allowing it to blend seamlessly into luxury decor. By choosing the Sonus faber Gravis I, you aren’t just adding a bass module; you are adding a piece of Italian furniture that speaks to your commitment to quality.
3. Deep Bass Precision: Technical Specifications

4. Revolutionary Class AB Amplification
In an era where most subwoofers use cheap Class D amps, the Sonus faber Gravis I utilizes a high-linearity Class AB amplifier. This choice is critical for audiophiles. Class AB amplification offers superior control over the driver, resulting in a “warmer” and more natural tone.
The 8-inch ultra-long throw driver in the Sonus faber Gravis I is built with a treated paper cone. This material was chosen for its optimal balance of lightness and rigidity, ensuring the subwoofer can stop and start with surgical precision.
5. Seamless System Integration and Connectivity
Integrating a subwoofer into a 2-channel Hi-Fi system can be difficult, but the Sonus faber Gravis I makes it effortless. It features independent volume controls for High-Level (Speakon®) and Line-Level inputs.
This dual-connection capability allows the Sonus faber Gravis I to be connected to your amplifier’s speaker terminals and your AV receiver’s LFE output simultaneously. You can enjoy optimized performance for both music and movies without ever changing a cable.
6. Why the Sonus faber Gravis I is the Perfect Addition
If you find that your current speakers lack “body” or that your movies lack the visceral impact of the cinema, the Sonus faber Gravis I is the solution.
- Compact Footprint: Ideal for apartments and medium-sized rooms.
- Fast Transient Response: No “muddiness”—only clean, rhythmic bass.
- Versatile Design: Matches any premium speaker brand, especially Sonus faber collections.
