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.
