Bob’s design for a high-pressure (and miniature size) subwoofer was so unique that he got a patent from the U.S. Patent office. The significance of the design is that a physically tiny subwoofer can produce absolutely earth-shaking, sub-sonic bass at high volumes without loss of coherence or tightness. With the Sunfire True Subwoofer, a music and film enthusiast can have real bass in a room that could never support a large, bulky, old-school subwoofer.
The Sunfire True Subwoofer Signature is our flagship model. At 13 inches cubed, the Signature woofer produces mind boggling bass from a box which is a fraction of the size of its competitors. Powered by a special internal Sunfire 2700-watt amplifier using Bob’s patented Tracking Downconverter power supply technology, the Sunfire True Subwoofer Signature has no equal.
