In theory you want them equal length but assuming a difference of say 10 feet, you will hear a time difference of 1/27000 of a second, not significant, however the difference in capacitance, impedance and inductance may filter the sound in the longer channel ever so slightlt.
Of bigger concern would be the joint, I would not worry too much about unequal lengths but I would use on continuous cable.
You could put the 12 footers on both, but the surplus could cause bigger problems than it solves as they will have to cross each other or snake around to take up the excess and this could cause worse problems.
Let your ears be your guide.
