What you’re describing is usually the result of the polarity of the connection between the source and the speakers and can also vary to a lesser degree depending on the recording of the content being played, e.g., in phase or out of phase.
It appears the polarity of the “sound” is somehow affected by how the interconnects are either made or are connected. One easy experiment is switching the + and - connections on both speakers and see if you hear a similar results.
