Visonik Active Sub-woofer (Abbey Lane Area LE4)

*Spares or Repair* on offer is a Visonik Active Sub-woofer. It was left behind by a ermm.."delightful musical tenant" who has abrogated responsibility for dealing with his possessions by leaving it in the hallway. There's no power cable with it so I do not know if it works, so you accept it on that basis. If it doesn't, I'm sorry, if it does, great!
