BRAND: Sonus Faber
SERIES: GRAVIS I
Gravis I, a formidable solution for people wanting accurate bass extension for middle sized listening rooms; it’s a powerful medium sized subwoofer package representing 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.
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.
