Sub cable length?


Should I match the length of my speaker cables to the length of my high-level sub cable?

I’ve got an LFD/Mistral amp with LFD Spiroflex Speaker Wire (3 meters) to B&W 805’s and using a REL S/3 SHO sub with the stock power and speaker cables. I was going to get a Snigal Cable http://signalcable.com/relspeakon.html and was unsure if it made any difference between the standard 6ft (which is plenty long enough for my needs) or get a 10ft to better match the 3-meter speaker cables.

Thanks!

And sorry if this was a dumb question, I didn't find this in any past threads.

No, length does not matter. Nor does the wire. 
Just make sure it's on the chubby side.. Bass likes big copper.. Just works!!

Length doesn't matter. Wire does.
Electricity travels at the speed of light, not much time difference between 6 feet or 60 feet. 
Doesn’t matter.  Keep in mind that the sub’s driver is in a physically different box, therefore, it’s already not time aligned with the main speaker’s drivers
Hi Colindshots!  All the responses so far are fine. but not specific enough for a newbie. Length is not a problem; just use 14 gauge, or heavier (lower numbers). I have used 14 gauge solid core wire in 70+ foot runs in auditorium installations with no problems. 14 gauge lamp cord will do. Happy Listening!
agree length doesn't matter but wire does 
I moved from the stock cable to the REL upgrade cable for REL S/5 SHO and felt there was a slight improvement
