Default Effect of UV on drivers

I just built my first speakers - the BK 12 kit from Madisound. These are my first speakers with exposed drivers. One of the units sits where it gets strong sunlight (live in a passive solar home) for most of the day. What effect will this have on the driver? Should I cover it when not in use? Moving it is not really an option because of the room size and shape.

I would shield it from long exposure to direct sunlight, although glass filters
UV quite bit.

Hello Ralph,

i think your intuition is simply right ... i would regard
a cover as beneficial.

Some materials used for making driver surrounds e.g.
are more prone to aging under sunlight than others ...

Same for cone materials and coatings.

With a cover you are on the safe side.

Kind Regards
Oliver, RFZ believer (?)

Thanks for the comments, I think I will keep it covered when not in use - even if my wife thinks I'm a bit on the crazy side - actually she knows this is true

Cover all the glass with UV blocking film. It won't significantly alter the solar heating characteristics, but it will protect the speakers (and furnishings) from fading.
