For 15’ (4.57m ~ 5m), and for a DF 100 (106): a #4 awg cable is recommended.
The Bi wire of #10 awg (equals to 2x #10 awg in parallel) is:
1 ohms per 1000 ft, each so it equals* to 0.5 ohms for both.
But a #4 awg (as required has a resistance of 0.25 ohms!) So now you have only half of the recommended conductivity.
*:
Bi wire never did the Job. It’s a good trick to make double the money over speaker cables :-)
but not good for anything. They invented a BS theory for it, most fall in.
An analysis with Spice simulation SW shows (used by all analog design engineers),
that the single 0.5 ohms (per 1000 ft) does a better job than two of 1 ohm in bi wiring.
Thats, because most of the current goes to the low Fr. (woofer) and only
a small portion to the High. So now, with the Bi wire, only 50% left for the low, while most of the current flows there. A single wire of 0.5 ohms would hold better that current, than a 1 ohms cable.
I would say, if you go for a #4 awg, drop the bi wire.
