Adhesive Glue used to hold tweeter in mounts?

[atod]

Hi Folks,

I have a B&W LCR 60 center channel. I had to pull the tweeter and replace the dome because it was pushed in. The tweeter was held tightly into the plastic interlock (attached to the front housing) with some high viscosity glue. This glue was still pliable such that I could turn the tweeter out of the interlock with some effort.

Does anyone know what type of glue this is?

Thanks
