Will sun exposure damage my speakers?


I have a window next to one of my newly purchased JM Lab Electra 926s and since I like their look without the grill, I was wondering if I was hardening my cone surrounds or not. They are fiberglass "W" cones so I suppose they are ok but I don't know for sure. Has anyone looked into this before? Thanks! Arthur

That is what I thought. I usually put the grills back on on sunny days. I guess I will continue to do so! Thanks again

Yes,
Sun rays ultimately change all that is in their path.
With speakers it will bleach the cabinets, dry the wood, and also, affect the drivers, (surrounds) if exposed too much.
Sort of like the white rat tests. "If a rat consumes 12.5 Million gallons of X it causes cancer". Hell if he consumes anything in THAT quantity it will kill him.
Moderation, combined with some UV filtering will help.
Get yourself some liquid latex.  Foam surrounds that are failing absorb it like a sponge.  A few coats works wonders and adds years to the drivers.
