Subwoofer Speake Cable - Important??


So, I'm using an old pair of Linn K-20 speaker cables to drive my sub. They're just a pair of multistrand copper cables. I figured no point spending good money on speaker cables just for my sub right? Mind you, I do believe in the value of good cabling for full range speakers. Is my logic sound?

I have a REL Stentor,and switched from the generic cable,supplied,to one from "The Cable Co".Cost was two hundred bucks.Made by XLO,and very well constructed.The difference was CLEARLY an audible improvement.NOT earth shattering,but more weight,and a better sense of air.Sorry,like me at first,it cannot be rationalized.
I upgraded the Rel Storm 3 stock cable to an aftermarket version which is much thicker and has nicer connectors, etc. It looks great, and I like it, and am satisfied. I cannot say that I noticed a huge difference in sound, although I did not go back and forth, stock versus new and vice versa, to verify or refute this. So, maybe I SHOULD be hearing something that I'm not. I've no intention of running a bunch of "tests" to see one way or the other, though. Others HAVE claimed to have heard a significant difference with this upgrade, so I may be "wrong."
