Closest to the speaker body: speaker cable spade.
Middle: R-C filter spade.
Top near nut: ground control spade.
Tighten down as much as is safely possible, and use CAIG Pro-Gold or similar contact enhancing and protecting fluid.

Great, that is exactly what I thought. Thank you so much! I use Kontak which is what I plan on using.
My GE's are due to arrive sometime mid next week. It will be most interesting to hear them compared to the reference AP GC versions I now have. I really do like the reference a lot from the standpoint of details and imaging which, in surround is quite astounding. However, I think they truncate "slam" a bit. I definitely do not note dynamic improvement over no GC in the speakers. I am hoping that the GE will be roughly the same with the Walker type RCR array attached to the upper posts. If so, the AP's go back as I have about 10 days to go or so on my 30 day trial and the cost differential between the reference GC and GE is quite enormous for 4.5 pair.
Thanks again!

As I read here, they are not RCR arrays at all. They are simple R-C pairs.
The R-C and R-C-R arrays are posted here under Al Sekela and CDC, if you want to know how to implement a more sophisticated device. And Awe-d-o-file makes them under the Econotweaks line in a multicap R-C version too.
These are synergistic in my system with the ground control tweaks, so don't eliminate any of them!
Do you still hook this up to your negative terminal if your preamp inverts phase ?
Seems to me, yes. It is the ground which is involved, not the absolute musical phase of the electrical signal. Example - hook up your amp/spkrs with +/+ and -/- as normal. Invert your signal at the source, say a DAC and the phase of the signal changes but not the negative ground in the circuit. Same with an amp that inverts absolute phase. The negative terminal on the output is still the ground as far as I know. It is the input circuit that inverts phase at some point in the circuit.
I would email Ric and ask him to be certain, but from my meager, ancient, electronics class education in H.S. eons ago that is what I would expect from looking at a typical amp schematic.
