Any wire pair has inductance and capacitance. Both are measured and indicated as a per foot entity. Inductance is typically in nanohenries per foot, capacitance as picofarads per foot.
The inductance of a cable will act as a low pass filter to signals. A woofer for example, may have one in series with it to allow only low frequencies to get to the woofer.
If you put a lot of inductance in the wires going to the speaker, it will do the exact same thing. Since wires have far lower inductance than a normal crossover, it will tend to act at much higher frequencies, what AJ referred to as rolloff, as in a reduction of the higher frequencies.
If you want to reduce the inductance of a cable, you make the wires closer together. Because the anticables do not control that distance, the inductance it will have is unknown.
I used the Terman equation to develop those graphs, the length enhancement goop is just a part of that equation that comes into play when the wires are short..I mentioned that I didn't use that part of the equation, but merely guessed that the inductance may be as high as 5 uH. A simple lumped element model puts the break frequency at about 100 Khz for 4 ohms, which is way high..to get to 20 Khz requires about 31 uH at 4 ohms..
I'd do a t-line run, but I don't know the capacitance of the cable..

That's what the center speaker is for, it acts as a reference position, and the testing will compare the virtual image of the pair against the reference. So don't worry about a head vice..it works around that problem..
