Guessing this will probably fall into the "local only" category seeing as it's pretty big...
For Sale: Polk RM6880 Powered Subwoofer
I just upgraded subwoofers. This RM6880 subwoofer was originally part of the RM6880 and RM6881 Home Theater speaker packages. It provides plenty of low end both for music and lots of rumble for sound effects in movies. It's in excellent condition and has only a little bit of wear on the corners that could easily be touched up.
My camera flash managed to pick up a lot of dust on the top that could be easily cleaned off with a damp cloth.
