 SUNFIRE TRUE SUBWOOFER EQ SIGNATURE with two 12" woofers.  

     From the Sunfire web site:

Don’t let its diminutive 13" cubed profile fool you. The True Subwoofer EQ Signature will likely generate more earth-shaking and musical bass than any sub you’ve ever encountered. It’s a true, flagship product with a massive 116dB of crystal clear output, delivered with the precision of Sunfire’s two most coveted and patented technologies. First is the 5th- Generation high pressure, High Back-emf design, which produces extraordinary levels of bass energy from an impossibly small enclosure. The second is Bob Carver’s Tracking Downconverter™ power source, used to supply its amazing, internal 2700-watt amplifier.
