Polk Audio 10" powered subwoofer (home audio) $65

I recently sold the rest of my home stereo system and this is all I have left. Less than 3 months old. This thing sounds amazing for the size it is. Perfect for action movies, and sounds great with music. It rattles pictures on the wall. There is no scratches or chips anywhere on the box or the sub. Just is a little dusty on top in the picture. $65 

part number is Polk Audio PSW10

Here is the link from where I purchased it

A subwoofer definitely improves the surround sound experience.
