Sunfire True Signature Subwoofer

I am selling my Sunfire True Subwoofer Signature, which is the last component from my dismantled high resolution home theatre system. It is the only component that wasn't upgraded due to its stunning performance on low frequency effects (LFE). I originally intended to use it in my very modest present home theatre, but it overwhelms the sound bar and the much smaller room.

The unit is in flawless functional and physical condition, and I'm the original owner. The original user manual, factory packing, a copy respectively of Bob Carver's Subwoofer Whitepaper and review of the True Sub Signature by Sensible Sound.
