This is the subwoofer that started the revolution. At 11 inches cubed, the Sunfire True Subwoofer (now generation IV) re-defines the term "spouse friendly." The True Subwoofer Mark IV is small enough to fit into practically any music or theater system. It's easy to set up and position to quickly add stunningly high levels of deep and musically accurate bass to your system. The True Subwoofer Mark IV incorporates two of Bob Carver's patented inventions: First is the high-pressure, high-back-emf design which allows creation of incredible levels of bass energy from an impossibly small enclosure. Second is Bob?s Tracking Downconverter power source used to supply the internal 2700-watt amplifier. This subwoofer has absolutely no performance equal its size.
