I didn't really know where to put this, so figured some tech heads in here may know.

I have a good set of Klipsch computer speakers that has a powered sub. While it was in storage, the public storage had a water main break and i was lucky enough to have the bottom of most my boxes saturated with water. The sub was at the bottom of one of them. After getting it out, it still functions, but has a heavy buzzing which seems to go away as it warms up, but it comes and goes after that. Is this something that I can diagnose and fix?

Sounds like rust and/oroxidation may have developed on the terminals or the wire connection at the magnet. As the speaker warms up, it's able to make a better connection and decreases/eliminates the buzzing.

Solution: Check the outside connection terminal for any sign of oxidation or rust. If no visual sign of oxidation/rust, you'll have to open the enclosure to check inner connections (inner terminal connections and connections at the magnet). You can use vinegar to eliminate any rust/oxidation you find.
