@drumbeat. I am not doubting what you heard but you should switch the cables on the left and right speakers and try the A/B test again. Very few listening rooms are totally symmetrical. I can hear slight differences in bass response between my left and right speakers (using the same cables).
.
I tried repositioning the speakers but the way my room is set up I will have to live with it. But they sound great together and I don't notice anything.
