Maybe cables matter, but y’all understand that bi-wiring does absolutely nothing, right? You’re still sending a full-range signal down both pairs, the crossovers still do their low-pass/high-pass roles. And at 10-12 ft the series resistance is still a small fraction of the series resistance of the low-pass inductor.
If the speaker wires are separated at each of the crossover input leads, the amplifier will indeed still send full-range signal to it’s own output jacks, but shouldn’t the same capacitance that prevents current flow for low frequencies from going to the tweeter also prevent those frequencies from traveling down the respective wire at wherever they junction at the amplifier outputs? As in, essentially becoming an extension of the capacitor circuit leads? (and then the inverse to the woofer due to the inductance on the woofer speaker wire?)
To the OP, I wouldn’t think a 2 foot length would make an audible difference.
