I never said that and you might want to go to the Passlabs web site and inspect the rear loudspeaker connections they use.....
No modification necessary for the WBT spades. 8 mm size actually
One the 8 pole thing, well the speakon I used had provison for 6 conductors so it would handle the mid, high and UHF spectrum of the 4344 external crossovers I made for Porchedman some years ago.
If you search under 4343 modifications there are images.
We're watching you.

If you do plan on an external network you will need to arrange a suitable means of cabling to the outside world. I used an 8 Pole Speakon Plug and Socket. There a several advantages with this style of connector, its air-tight, has very good electrical characertistics, takes a 13 gauge cable and the polarity of the individual driver cabling is identified and maintained without fear of error.
