Power outage and blown subwoofer...???

So the significant other was using teh microwave and the toaster at the same time. This blew a fuse. So she opens the fuse box...and turns off the wrong switch. The audio system stops for maybe one second. She immediately turns the switch back on. After that, everything works except the subwoofer in the right speaker (they're full rangers with a sub built in to the base). The sub in the left speaker works fine. Right one...nothing.

Any ideas/help/ways to avoid buying new speakers?
