My unusual set-up requires 16ft on one side and 9 ft on the other. I have tried every possible combinations. Equal lengths with one side coiled, equal lengths with no coiling but a mess, name it. Cheap cables, expensive cables, homemade cables, Home Depot cables, heavy gauge, light gauge, and probably a few other combinations.
What works for me: I use a 16ft on one side, and 9ft on the other. This shifts the stereo image to the short side on the 9ft run.
I counter-balance this by advancing the 16ft side speaker about a foot in front, and the image centers beautifully.
I have always used this way to get a virtual channel balance control even with even-length cables for micro-adjustments.
Not saying it would work for you but worth I try!
Good luck
