Bose Acoustimass 10 Series III home surround system. Comes with the subwoofer, 5 speakers, some cables (including a special flat cable for running under carpet) and some mounting brackets for the rear speakers. The system was working perfectly when it was disconnected from my parents' home theatre. They are downsizing and no longer have the room in their new residence. It is being sold for them. It is in great condition, clean and from a smoke-free home and sold as it.
