Yes, it will. It will cause premature failure of foam surrounds and fade parts of the cabinets that are exposed to the light.
Having said that, i'm in the same situation with one of my systems. As such, i treat the cabinets with Lemon oil, which keeps them from drying up and helps retain their "rich" wood finish, and i rotate the speakers. This keeps the "fade" relatively consistent between the two, yet does nothing for the other side of the cabinet that isn't exposed to light. Sean
