RCA cables to a subwoofer- how much does it matter?


I’m using nice OCC interconnects, balanced and unbalanced, in my system at all points except between my preamp and subwoofer, where I’m using a 12 foot pair of Blue Jeans unbalanced interconnect. My sub sounds great and with the crossover set to about 45hz, my sub’s main focus is really no more than an octave. 
 

I am using a single sub- a McIntosh PS112. The cable I’m using, if I’m not mistaken, is sourced from Canare and is shielded. For use with my subwoofer is there any point in using a different “higher spec’d” subwoofer cable?

Darned if I know, I'm also hesitant to spend a lot for just the deep bass.I just have some cheap Monoprice cables.I suspect an upgraded power cable would make a positive difference, it certainly has on my amps.I've been considering that, but have yet to try.

I used Blue Jeans cables when I had four subs,for the two on the front wall.Then longer Monoprice to daisy chain the other two in back.Nothing wrong with BJ,well built and attractive.

You guys motivated me to try a Cullen 10 gauge pc on one of my two subs(I only have the one).I'll repost tonight if it makes any difference. If so I'll spring for two to use permanently on the HSU subs I have currently.Cullen also sells RCA cables that I haven't perused yet, but I mention it in case anyone is interested and wants to take a look.
