Elliott, Lewm is correct in that you have to measure the resistance of the L pads when they are in neutral position. It may not be zero. I think it is best to do what Lewm suggested. Set them up so that they sound good to you. Then measured the resistance and substitute the appropriate resistors.
Wires that run parallel to each other have the highest inductance. In other words one wire will induce a current in the next wire. Wires across each other at 90 degrees have the lowest induction. I believe the wire in cat 5 cables is parallel. Wires in a twisted pair are always approximating 90 degrees to each other and therefore have very low induction. IMHO the best wire made for loudspeakers is Kimber Kable. It uses smaller gauge wire woven in a pattern that keeps induction very low and because the wires are very close to each other parallel resistance is low. As Ralph relates you keep series resistance low by keeping the wires as short as possible. For 16 ohm speakers 18 gauge twisted pair is more than adequate. If you want to go ballistic buy a set of the higher gauge Kimber Kables. My amps are right under the speakers and I use 3 foot runs of Kimber Kable 12TC.
Lewm, I finally ordered my Sound Labs!! They are a custom size, basically 845s the width of 645's, a little narrower. They will fit my situation better. Roger is supposed to be giving me an ETA today or tomorrow. You mentioned that you modified the interfaces. Did you just bypass the controls?
