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

Yes keep them out of the Sun. As an engineer of 20 years in the polymer field you should keep your speakers out of direct sunlight.
We may have found a thread on which the vast majority of audiogon participants agree! Success!  ;) 


UV is not good in the long term for most modern surrounds, cones and dome materials.
