I'm still gathering the parts list and it seems more fitting to continue here. This is continuing from my original post:

Regarding the 1.0 mH 7.5ohm, I have decided to use a 1mh .7 ohm dcr and add a 6.8ohm resistor in series. The parts availability is better and seems acceptable to do this.
I'm contemplating on ordering a speakon 8 conductor cable and associated hardware. This will go from this external network to the speakers. The input side of the network will be 5 way posts / banana jack hardware.
The padding resistors will most likely be interchangeable via terminal blocks.
I have spent some time researching the possibility of an active crossover. This would eliminate quite a few passive network parts. The good ones seem to be very expensive and I don't have the ability/equipment to measure the setup. I would still end up with the upper frequencies handled by a passive network. To add to the complexity, there is already an active crossover for the subwoofer. Just seems like more room for errors at this point.
The main reason for the bi-amp quest is to use lower power tube amps and sweet sounding SS on the upper frequencies. The LF will be powered by a professional SS amp.
Would any of the network component values need to change if I separated the LF section from the rest of the network?
The components are expensive, so I want to do it right the first time.
Again, I'm using the schematics posted here:

Thanks for these btw. Comments and advice is always welcome
