I'm still gathering the parts list and it seems more fitting to continue here. This is continuing from my original post:
http://www.audioheritage.org/vbulletin/showthread.php?28670
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.:dont-know:
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:yes:
