Sunfire awarded U.S. Patent for StillBass Anti-Shake technology

First introduced in 2008, the Sunfire SubRosa Subwoofer is the world’s first flat panel subwoofer.

In-wall subwoofers used to face a huge hurdle – the drywall would crumble and turn to dust from the constant mechanical vibration. While designing audio components for Sunfire, Bob Carver developed an innovative solution to this problem by utilising Newton’s Third Law of Motion, using an actuator that moves in opposition to the woofer to virtually eliminate destructive and intrusive mechanical vibration that subwoofers naturally produce. By controlling the subwoofer’s 'shake', StillBass technology allows the woofer to be placed in a wide variety of locations rarely considered for high quality bass. The SubRosa can be mounted on a wall, located below a big screen TV, behind a couch or under a bed and even inside the wall. This newly patented technology is only available from Sunfire, and at the moment, only in the SubRosa Subwoofer.

“Sunfire’s patented StillBass technology shows that we are committed to delivering the ultimate home audio experience through design and attention to detail,” says Sunfire general manager Mark Weisenberg.

The Sunfire SubRosa subwoofer is delivers bass through dual 10” woofers and combines neodymium magnets with inverted surrounds, resulting in a sealed enclosure with a depth of only 3.75”. The Subrosa In-Room Subwoofer System comes with an external 2,700W Tracking Downconverter and features infinitely variable crossover, phase and level controls. The system includes balanced XLR, RCA and speaker level inputs and features auto room correction through use of an included microphone.
