Sonus Faber Gravis I

The Gravis I powered subwoofer offers an ideal balance of size and performance for smaller listening spaces.

Gravis I, the most compact powered subwoofer in the Gravis collection, effortlessly harmonizes with diverse listening environments and audio systems. Gravis I seamlessly complements the aesthetics and acoustic characteristics of the Sonus faber Lumina collection and the smaller Sonetto bookshelf models, such as Sonetto I & II.
Custom-designed drivers and amplifiers integrate seamlessly within Gravis I, delivering powerful depth with more efficient power consumption.

Gravis melds decades of Sonus faber design and audio expertise into a contemporary package, enhancing the depth and clarity of our Natural Sound signature in a seamlessly integrated design.

The independent volume controls for high-level and line/LFE offer effortless calibration for both music and home theater applications, eliminating the need for constant adjustments. The High-Level Connection ensures a seamless fusion with main speakers during music playback, while the LFE input enhances the immersive home theater experience.
