No one actually knows how to lculate what speaker cable they need

OP
The ml3 has select able DF 100,200, and 300 at 50Hz. The ribbons are from the Infinity IRS. Actually I am tri amplified, another ML3 and a ML9 on the top. I can run active or passive on the crossover and  do switch back and forth if any of that matters. Does that change anything? When I am active crossover there are no coils. How does that affect your recommendation?
Thank you

I'll quit this game, till the OP's end. It is getting a bit weird. 

Mr.  keppertup
Good Luck. How exactly do uou have in mind connecting the  0 AWG copper wire for $23 to the amp and speakers?

The ribbons are from the Infinity IRS.

The Infinity IRS uses planars, not ribbons.

Mr.  geoffkait
You bett right.
On cryogenics or burn inI answered already.
Directionality: Audio is an AC. That means that every 1/2 wave is flowing in the opposite direction of the other 1/2.
Please be kind to explain, who is changing the cables  directionality so many times a second...?
All home apliance use AC (at yours 60HZ at mine 50Hz). What about them? The electricity STD defines which is the hot line and which is the return. Try to convince them about  directionality. 
It is amazing, what kind of crap sales guys are trying to pull with Audiophiles that have no understanding in electricity, but are deep into spending large on the beloved hobby.
