From the Sunfire website: "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.
Still want more? The True Sub EQ Signature gives you balanced inputs, a measurement microphone and internal contour circuitry that automatically optimize the subwoofer to your individual listening or viewing room. It is truly a one-of-a-kind product with absolutely no peer. "
I have four of these wonderful subwoofers. I recently purchased two from a Sunfire salesman, who used them in his system for two years. I was going to use them in conjunction with my new Joseph Audio Pulsars. The Pulsars surprisingly do not need them.
I have the original boxes and microphone for automatic equalization.

I have four of these subwoofers, and two of them are for sale. Both are in perfect condition, but I have rated them 8/10 so no one can complain.
