It could also be the powered monitor took a hit. The pop or thump when the output was accidentally pulled out could have blown the speaker. I just has to replace four speakers at my church that were blown when someone tripped on a mic chord and broke the XLR connector. It was not that loud but the speaker coil was damaged (not the cone). You might try the monitor speaker with some other source to test if it is okay.
