    Question Are UV rays damaging LS membranes?

    Hello, I have positioned my 40.1s (without grills) close to a window. For some hours per day sun is shining directly on the front of the speakers. Is this a problem for the membranes of the speakers? Do the UV rays damage the membranes? Thank you

    {Moderator's comment: yes I would expect the UV to attack the cones and surrounds. The recommended use (as per the User Guide) is grilles should remain fitted.}

    Default Do not let your speakers bake in the sun

    Definitely not a good idea in my experience, with any speaker.

    Personally, I would leave grilles on and draw the curtains or close the shutters. Don't leave them to be baked in the Sun.

    Default UV through window glass?

    not only the elements covered by the grilles, but also outer veneer doesn't like direct sunlight...

    But, is it really UV that ruins them? Because, almost 90% of the UV is already blocked by ordinary window glass...
