Power cable choice, does it matter for subs?

Should replacing the PC on a subwoofer make a difference you could notice?

I just discovered I had accidentally installed an18ga cord on one of my subs. It was the most power hungry of the bunch and I feel bad about starving it. I did install a stock type 14ga I found in house and it did seem to tighten it up a bit but that could be my imagination. 

In your experience, any thoughts on if going to a better/higher gauge cord on subs would or should make much difference?

Yes, I think what you heard was thin wire. My DBA was run restricted like this for some time. Long story, but unbeknownst to me the sub amps were plugged into a current-limited outlet. The bass was still quite good, at least I thought it was until doing some more mods I discovered my error and fixed it. The sense of speed and slam or impact improved noticeably.  

Other than that though I have tried various speaker cables, interconnects, and power cords, hearing little to no difference. I now have some Synergistic Atmosphere power cords for review so maybe this will change. For now though it seems subs need adequate gauge and good power, but are nowhere near as sensitive to power cords as other components are.
Thanks for the response, I think the 14ga has helped over the 18ga and that should be enough,
Long time ago owned REL Stentor subs and yes a better ac cord made a significant improvement in sq. 
I believe I hear an improvement using 12 gauge aftermarket power cords on my REL subwoofers (two pairs used in two different systems). You don't have to break the bank just using $150 or less upgraded power cords.
If you want to HEAR the difference between cables - try listening to Church organ music
  • it contains the "textures" that most bass lines in music lacks
If you want to SEE the difference between cables - take a video while playing church organ music and then play it back in "slo-mo"
  • the difference is quite visible
  • it also shows just how good the cables and the amp in the sub really is
  • things will change with a better power cable
HiFi Speaker Movement in Slow Motion - YouTube

It will also show you the distortions the cone goes through
- the better the amp and power cable, the less distorted the movement becomes

Subs draw a significant amount of "instantaneous" energy and a quality power cable can better handle that demand.

Trouble is which one do you buy? - because not all power cables are "equal"

  1. Money no object - InaKustik - amazing products
  2. Nordost has a decent lineup - from affordable to astronomical
  3. KLE Innovaitons - are affordable and very good
If you are "handy" - a great DIY solution is the Helix IMAGE "Air’

If you are concerned about the price of this DIY solution
  • use a more affordable wire
  • the Geometry of this cable provides most of the benefits

But then again - if YOU can’t HEAR it - why bother?

I trust my ears, but I do love my cables :-)

Hope that helps - Steve
