to quote DonH50 "It looks like a glue they used to minimize vibration of certain components, the PCB, and the leads through the chassis. Pretty common for amps inside speakers where they are exposed to high-pressure sound waves."
Don is right, it is to minimize vibration. Some high end speakers, like Sonus Faber, encapsulate the entire crossover for this same reason.
