What about using cheap coaxial cable? Is coaxial geometry a bad idea for speaker load engineering?
There's old pure copper coax surplus around with loads of copper eg 13AWG giving low resistance and less then a dollar a foot. It will be dam stiff and bit of a hassle to connect.
Specs:
Conductor DCR: 1.9 Ohm/1000ft
Shield DCR: 1.5 Ohm/1000ft
Nominal Characteristic Impedance: 50 Ohm
Inductance: 0.08µH/ft Nominal
Capacitance: 29.5 pF/ft Nominal
Velocity : 65% Nominal
Delay: 1.4 ns/ft Nominal

About any geometry will do.
Coat hanger wires do fine. They came in the best ones in a blind test.

You could parallel 6 and get ~8 Ohms and we could loop back or branch to any number of previous threads.
Just use thick copper wire. No need for fancy stuff.
We don't use fancy wire created by elves in the moonlight in professional studios. The production gear is hooked up with copper, the only difference is we use decent connectors so it can withstand a lot of plugging/unplugging.
Besides, the internal wiring of speakers also uses standard copper cabling, unless you're buying woo speakers made to impress people with their price.

My thoughts exactly. I am not aware of any professional studios here in Music City using any cabling that costs thousands of dollars per meter. Mogami, Canare, Belden, Gotham, Sommer, etc is what you see used.
How does a recording made with these studio cables become magically transformed, when a 10,000usd interconnect set of cables are used or a 5000usd AC power cable is connected in the home audio system.
Wow. Car salesmen have nothing on the so called high end audio sales!!

Cross connecting I just using two runs of coax to one speaker. But instead of simply paralling them, sever them halfway, then reconnect them but shield to core and core to shield.
All it does is retain the same capacitance and resistance, but adds some inductance.
I had calculated the effective inductance for Jon years ago, he eventually confirmed my analysis.
But, it's nothing magic.

Hmm, been about 15 years, I think I described it correctly..

No, I know how to do it, but I just don't understand what it does, in actuality. I mean, instead of crossing the cables, couldn't you just as easily strip back the plastic insulator, like 1-2" from each end of a single run, and solder the shielding to the conductor? Is there a function to the crossing?
Belden cable, Canare connectors, job done
If you don't want to make cables yourself - go to Blue Jeans.
Anecdote: 15 years ago I needed 20m component cable (video) for 1080p to hook up my video beamer. People on internet fora said I'd need ridiculously expensive cables for that length and resolution.
I talked to Blue Jeans, they guaranteed(!) me their cable would work perfectly, made me a custom cable to length, shipped it to Europe.
Still much more affordable than anything I could buy here (guaranteed to work), and it worked perfectly - no signal degradation whatsoever, perfect picture.
These guys make quality cables without the audiophile/videophile bullshi*, and they will stand by them - proper return policy if you're not happy with them.

On second thought, that's not gonna work, since the the shielding is steel. LOL
