Will sun exposure damage my speakers?

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

Yes, absolutely! During the course of the year my REVEL sub gets quite some sunshine and I cover it with a towel during that time and days. Whatever rubber is used for the cones: it doesn't like the sun at all.
Good luck!

YES!

Direct sunlight will "cook" foam and the plastic resins in the
fiberglass cones causing them to become embrittled which
ultimately leads to failure.

I'd keep the speakers out of direct sunlight.

yes... plan on using a heavy duty window tint.

If the position allows too much light and you don't have options or glass tint is not of your liking, you might consider adding a fabric cover to your speakers to preserve them. In other words if you leave to work early in the morning and get back early in the evening, your speakers will stay all day long getting the light exposure without you enjoying their look. The covers can be made of decor color matching fabric, perhaps your S. O. stays all day long in the house she can put the covers to lessen the visual obstrusive boxes in your den or living, so maybe you can have a win/win scenario and improve WAF. My 2 cents.
