If you swap the R/L cables, and the problem is in the interface, the problem will go to the other speaker.

Have you tried that?

HOWEVER... that doesn't mean anything other than it's not the actual speaker having a problem. If it moves with the cables, it is either an interface issue..... probably NOT the case, or it is a mix issue, more than likely the case.

Examine the mix and start by going through the tracks and being sure everything is panned to the center. Often if you are not balancing the mix when you pan, you WILL end up with a lopsided mix or one that has more brilliance in one side vs the other.

A quick test is to post THAT song you're talking about here for people to listen. If it's got a problem, we can hear it and confirm it.
