xover rattles?

[jondog]

I bought a pair of used PA cabs. [I didn't post this in Live Sound because many bass cabs also have xovers and Amps gets a lot more traffic.] One sounds great, the other has a rattle that I tracked to the xover. It's a fairly large xover circuit board w/ a big attenuator pot and two other big round copper devices. I tightened all screws, but it still rattles with some notes. Any ideas? If I can find the rattling component can I just cover it in hot glue or something?

industrial hot glue - squeeze it all over the coils and caps and press then down while it cools.

Silicon sealer also works but you have to let it dry a couple of days before re-installing.
