The goal of Sonus faber's new line of Gravis subwoofers was to create a versatile product that can be perfectly integrated into every living environment.

Though the series is an ideal match with Sonus faber’s new Sonetto Collection, Gravis subwoofers will boost performance in almost any type of music and video system.




Gravis I is a formidable solution for people looking for accurate bass extension in mid-sized listening rooms.

It is a powerful medium-sized subwoofer that delivers an ideal compromise between size and performance. It features a down-firing 8” active driver, along with a high current 150W Class AB amplifier allowing it accurate and expressive bass reproduction well beyond its class. A highly-advanced preamp stage is responsible for the texture, speed, and attack of the smaller Gravis subwoofer models.

Moreover, Gravis I's rear panel features a complete connectivity solution that allows for both perfectly blended musical sub bass and powerful, percussive, home theater bass. A wide sound field reproduction is the result whenever this subwoofer unit is matched with a loudspeaker system. Its sound is rock-solid, fast, and has startling depth.
