I was in the same boat. Had a pair of speakers go bad about a month ago, opened em up, saw a bunch of bulged capacitors. Tried my hand at replacing them, wasted way too much time doing it; in the end I didn't fix them. I either burnt something while desoldering or something else was borked.

I bought a new pair, but I walked away from it with more or less of a warm and fuzzy feeling that I did what I could. And a semi-decent soldering station, so next time this happens I will try again.
