Beat up pair of SDA CRS's. Probably no cable though. Dude has no idea what he has. Thinks they are subwoofers. Currently for $.99. Bid low and pray no one else discovers it, might get a decent pair of speakers for a song.
I wouldn't pay over $150 for them though. They look to be in rough shape cosmetically and with no cable and the idea that the dude has probably only run LFE signals to them, there's no telling how beat up they really are. Get them cheap though and worth the time and cost to fix them up.
