If you seriously want to BUILD cables check out the following poster under Cable forum.
Williwonka DIY Helix Geometery Cabling.
Post has continued for years. ALOT of great info and alot of posts from DIYers using these methods.
If you stick with your original plan, the Worlds Best speaker terminals are "None". Less is more. You need external XOs or easy access to XO circuits. Soldier speaker wire directly to XO circuit. Eliminate all that treminal stuff. Obviously not a good option if your a cable junkie and swap out cables periodically.
I chose this method when I rebuildt and made my XOs external. Saved big $ on the "very good" treminals I consdiered using.
