GRAVIS II


Gravis II, a fitting choice for more demanding audio systems, it represents design synergy at the highest level. It features a front firing 10” passive radiator with a down-firing 10” active unit, along with a high current 400W Class AB amp. The combination of a larger cabinet, perfectly tuned to the larger driver compliment and 400 watts of refined power provides excellent bass extension with the speed, impact and nuance required to underpin the most engaging music and theater systems.

Overview


GRAVIS SUBWOOFER COLLECTION
Sonus faber is not new to the arena of subwoofer design and engineering. In fact, the Vicenza based company’s first subwoofer project, the Gravis FB100 was launched back in 1986. Ten years later, the Sonus faber Cremona Subwoofer M became a popular solution for home theater enthusiasts and two channel aficionados alike. More recently, in 2014, Sonus faber applied its unique knowledge of speaker design to the highly regarded Sumiko Subwoofers S Series.

The new Gravis collection is comprised of four models: Gravis I and Gravis II, smaller models ideal for matching with the new Sonus faber Sonetto collection, Gravis V and Gravis VI, more powerful and high-end models designed as a perfect complement to the breathtaking Homage Tradition and Reference collections.

For over three decades, driver design has remained one of the most important factors of Sonus faber’s loudspeaker systems. In fact 100% of the company’s current product line features drivers that are designed and developed at its laboratories in Vicenza, Italy. From this rich knowledge pool emerges the care and attention required to design and produce relatively small driver units that provide truly low bass and are able to withstand high power and output for long periods of time.

Both Sonus faber Gravis I & II use quality stamped steel-frame speaker units: the Gravis I features a 8” Ultra Long Throw down-firing speaker unit and the Gravis II uses a 10” Ultra Long Throw down-firing speaker unit and a 10” aluminum alloy diaphragm passive infra-bass radiator.
