Needed: imedance cable 6mm

[roguenone]

I own a yamaha yas-71 soundbar, quite old
I'm having trouble identifying the right cable
I'm looking at the port and online and nothing seems to fit
to all you sound experts here
I'm attaching a picture of the back side of the soundbar
does this part supposed to hook with the subwoofer ?
in the user manual it says there's an australian cable and us standard
but maybe i read the wrong manual, or its a newer yas 71 ?

some clarification is needed, and ultimately where i can find the cable
please refer to the picture for ref to your answer

They are oddball speaker jacks so only Yamaha would have speaker wire with the correct plugs.
You can see that there are two flat metal contacts in each. Wires could be soldered to those contacts which could be used with different terminals or regular speaker wire just spliced and taped so they don't short. The soundbar seems to be passive so the same could be done to it or new terminals installed.
You do have the system control cable? Without that you are screwed.
