Help! What's the white glue coming from Celestion SL600SI

Hi,

Help! Can anyone help me make sense of the white gluey thing coming from Celestion SL600Si? I purchased them used from a seller here, have enjoyed them for 2 years, and noticed this anomaly today. Not sure when it started to happen. It looks like melted glue. See the pictures below:

I have done so many times for different reasons, and I've never seen anything like that. I doubt that it's the crossover. The crossover in these speakers is at the bottom of the box, and it's shielded by thick foam. It might be something that the previous owner put behind the plate for some reason. Screw it off and investigate.
