I'm not sure about this one. You may wish to contact Bose, provide them with the serial number and they can tell you how old the system is and when it was manufacturered and sold. There are no orange labels on the back of my tower

Also, plug it in and let us know how it sounds--you may want to keep it.

Cheers,

Gary
