Sunfire recently announced it has been awarded a U.S. Patent for the StillBass Anti-Shake technology featured in the company's ultra-thin Sunfire SubRosa Subwoofer.
While designing audio components for Sunfire, Bob Carver developed an innovative solution to this problem by utilizing Newton's Third Law of Motion, using an actuator that moves in opposition to the woofer to nearly 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 inside the wall. This newly patented technology is only available from Sunfire, and at the moment, only in the SubRosa Subwoofer.
The Sunfire SubRosa subwoofer uses dual 10" woofers and neodymium magnets with inverted surrounds, resulting in a sealed enclosure with a depth of 3.75". The Subrosa In-Room Subwoofer System comes with an external 2,700 Watt Tracking Downconverter and features 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.
