Creases in Nautilus 803 Woofers

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


Thanks,

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?

[windshear]

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.
