    Creases in Nautilus 803 Woofers

    Any idea what might be causing these small creases in the surrounds? These speakers have never been run hard.

    I see the rubber surrounds also have cracks in them. Have the creases developed recently or always been there? To me it looks like a bit of a botched repair job with lumpy glue and bubbles. Almost like the substrate got wet from something if you look at the discolouration.

      If I had to guess I would say that you live in a very 'dry' house and the surrounds are cracking due to a serious lack of moisture in the air.

        Seems to me that they've been developing over time, all 4 woofers have the same creases. The drivers have never been repaired and are functioning fine. The speakers are in the same room as my guitars which has a humidifier running in the winter so them drying out shouldn't be an issue. Any other ideas?

          Are they exposed to direct sunlight? How close is the humidifier to the drivers?

            My first thought is moisture. It looks like paper that got wet.
