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

While I have spent hundreds of hours experimenting with interconnects on components. I have only swapped cheap, good, and better on my sub woofers… never heard a difference. I have read that most folks have not heard any or significant difference on using great ones. Having said that… I always used relatively inexpensive subwoofer interconnects. While I am not a fan of Blue Jeans… you probably will not hear an improvement by spending more. I would buy a second sub way before I upgraded the interconnect. Two subs extend the sound stage and have a big positive effect on the system.

Lots of little imperceptible things can add up if you are seriously trying to get the very most sound quality out of your system. I always am. So I would not spend a fortune, but would buy subwoofer interconnects after you get your second sub. Emphasis here is: I would.

Thank you! I am skeptical that putting more money for sub cables will make a difference. I agree a 2nd sub is the best bet. As it is now, I am ahead of he curve as my sub was gifted to me. The idea of having two subs, JL Audio,SVS, etc., is quite interesting-

I upgraded my REL subs from their standard high level  input cables to their Bassline Blue Cables.  It made a significant difference for me!  Ken

It can all boil down to which kind of music you like. In a classical Orchestra there are a few sources of bass notes wind  percussion and string and each has a distinctly different type and timbre of sound. You also have low bass in hall effects so I would say in that type of music you are certainly going to hear a benefit from better cables. It also depends on how much of the bass spectrum you are using.

No, not in my experience. But if you use Fideliums as above on the mains you might desire to forgo the subs altogether.

I use three subwoofers featuring Blue Jeans RCA Subwoofer cables.

Beautiful, powerful, tight bass.....

It’s easy to borrow one from a good dealer. Try it and see.

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.

Depends on the audio forum.

In other words...

Exactly what I am using- sounds like a very good cable in this application 

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.

Update: The heavy gauge Cullen Crossfire pc actually made the sub sound worse.A little louder and more resonant/room filling. It was a relief to put the cheap pc back in. It tightened up and fell back into balance. Adjusting the volume and Q setting didn't help. Oh well, now I know:-) I like the Cullen very much on the ss  amp I use in the summer.I'll hijack your thread no longer!

Eh, not much of a highjack. Just a slight detour 

buy subwoofer interconnects after you get your second sub. 

+1.  Also, with the Cullen PC you probably need to let it burn in more until it sounds its best.  Patrick told me to not expect optimal performance until 100+ hours, so if you just assessed it right outta the box you might wanna give it more time.
