I have a set of Logitech X-520 speakers. As I gradually turn the volume up from 0%, the right speaker comes in at 5% while the left speaker comes in at 10% and they sound even at about 20%. About 10% is the volume I would listen to music quietly, but it is clearly louder in the right speaker at this level. This is the case no matter what I connect them to or how.
So I bought a set of Logitech z623 speakers and they had the exact same problem. I returned them for another set and they had the same problem too.
So my question is: Does every set of PC speakers behave this way? If so, why?
