I had this system for about 5 years and it is has worked flawlesly. Only used it for movies/music occasionally at moderate volumes. It includes (4) 2.2 satellites (1) 1.2 center and (1) S8.2 Powered Sub. Paid $850 originally. Asking $450 OBO. Still have all original boxes, instructions and wall mounting brackets. This review of the system, will give you any and all additional info you might need. http://www.avrev.com/equip/energy/index.html Thanks!
