When, like, actual scientists test diffs between cables the question is never which is better. It is "does this sound different?" until one proves a difference exists (like between speakers)...

Fwiw (dang little) I am pretty sure my xover is 60 hz. Very informal listening revealed no audible diff between xovers from 40 to 80 hz. Possibly my speakers compress in that 60 to 80hz third...
