Power cable choice, does it matter for subs?

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

Thank you Steve for the great video very interesting.
Right now I have four subwoofers plugged into a Hubble outlet. I am using a cheap three-way Splitter, and should probably ditch that soon.

 I may look into running a dedicated line as the four subs draw considerable current when playing at higher levels. it’s close to the mains box so should be easy enough. I know the existing 1930 era line to be original, and is not grounded in any event. The install of the Hubble outlet was a stopgap measure last year, at that time I was pretty astonished at how ugly old wiring can be.
