Is there a good low cost 6 - 10 AWG speaker cable for HT?

I'm hoping for something flat enough to run under an area rug.
Plus, for the closed box subs, which I'll make two of myself each with 8 Audiobahn Alum 12's, I was considering powering each off of a Crown K2 bridged (into about 6 ohms) and it occurred to me that, when set for high gain, the K2 bridged might offer enough excess gain so that a small amount of feedback around the speaker cable could be used as part of a passive xover working as a quasi-ELF between 16 and 40-50 hz. One LP pole would be purely passive before the noninverting Ch1 input of the K2, and the other would be taken as feedback from a small gauge 'sense' wire run from the 'noninverting' bridged output through a series RC network to the 'inverting' balanced Ch1 input with each SW speaker cable run.
The effective feedback would range from almost nothing below 16hz to about 8db @40 hz and possibly as much as 26 db at 300hz, although the fb would be reduced above this frequency and could additionally be easily adjusted down by modifying the passive values.
To avoid equilibrium destroying brontosaurian blasts of infrasonic oscillation through the speakers during the tweaking in process, the speakers would not have to be actually connected while the passive xover was being dialed in.
This potentially could be a very nice approach to doing a HT sw crossover, since it would be cheap, passive, and the feedback around the power amp would more than double the effective damping factor at the speaker terminals if it worked out.

I have never seen any "audiophile grade" wire that large. I would think that unless you are using a run of more than 100 feet, you would not need more than 12 guage wire. I remember reading of Tributaries having a flat 14 guage wire, but I have never heard it in a HT set up, so your guess is as good as mine as to whether it is good wire or not.

Better watch out for the capacitance. at anything lower than 10AWG

I'll have to mull my options. I've also found a manufacturer of ribbon cable with up to 24 18 gauge conductors per cable, btw. ITW makes 'Pan-Flex' ribbon cable, but it has a conventional grey PVC insulation. I don't know how easily obtainable it is in small qty.

In terms of cost and being flat, Audioquest makes F-14 & F-18, plus it comes in several colours to blend into the background better. It is around a dollar a foot.

You might look into PS Labs Lab Cable, although it's probably as thick as a garden hose. I don't know anyone who makes very large guage flat cables. What I ended up doing was running the very large cables (and long runs) under the house (get your drill out). It felt weird to drill a hole in my floor, but it really took care of cabling problems. Then you wouldn't have to worry about physical size, at least.
