Gravis III
The Gravis III active subwoofer delivers powerful and precise bass with signature Sonus faber style.
THE ULTIMATE DEPTH
Exemplifying unmatched power and elegance, the Gravis III active subwoofer is meticulously crafted to deliver striking bass performance. It seamlessly harmonizes with various sound systems and shares both an acoustic and visual affinity with the Sonus faber Olympica Nova collection.
ICONIC SONUS FABER DESIGN
Each subwoofer boasts an artisan-crafted wooden or lacquer top, enhancing its aesthetic allure. With its sleek, unembellished body, the design radiates a sense of purity and sophistication, complemented by Sonus faber’s signature leather finish on the sides.
THE PURSUIT OF DEPTH
Gravis adds beauty and depth to Sonus faber’s Natural Sound signature
EXPERTISE AND ARTISANSHIP
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 REAR PANEL
The Gravis III subwoofer offers versatile connectivity, accommodating both high-level and low-level signals. The high-level input employs a Speakon© 4-pin connector, while the line-level signals can be transmitted via balanced or unbalanced cables.
SPEAKER UNIT
Gravis III boasts a 10” (250mm) ultra-long throw driver equipped with a trilaminated sandwich cone diaphragm. This diaphragm comprises two layers of woven synthetic fibers (Fiberglass) with a layer of nomex honeycomb structure in between, effectively managing the driver's excursion and resistance flexing.
WIRELESS PAIRING
Gravis III can be wirelessly paired by using the Gravis Transmitter. The Gravis Transmitter transmits signals in wireless mode to the Gravis III active subwoofer, with maximum versatility in a compact form that is easy to integrate into any listening environment.
DEDICATED APP
The Gravis III is fully controllable through dedicated, user-friendly app. Available for iOS and Android systems, this app makes the subwoofers simple to configure and use.
