Duelund 16ga vs. 12ga


I've read some comparisons on-line, but am curious about others' experiences comparing these two gauges of Duelund hookup wire...

I currently have 16ga on a pair of Coincident PREs which require four separate runs of cable (to power the subwoofer and head units).  I'm trying to figure out if I should replace both sets of wires, or leave 16ga on either the head units or subs... or just stick with the 16ga on everything.  I have two goals, 1) to extract as much bass as possible out of my system, and 2) to get the most natural tones and textures.

Any input is appreciated.

I agree with twoleftears comment, I would also add that it depends on how long the cables need to be. In my experience I prefere the 12 gauge for bass runs. IMO anything over 8' (for bass) should be 12 gauge.
Runs over 8 feet or so the 12 gauge. 12 gauge Duelund has more bass and mid bass energy as well as increased dynamics.  The 12 gauge will give a little more meat on the bones, while the 16 gauge will be lighter on its feet and more nimble.  The 16 gauge will give more perceived air and details, but it is really not more resolving than the 12.  The 12 just serves it up with a tad more body and lower mids bloom. 
I wanted to bump this thread. I’m using Altec Valencia’s. Now running Duelund 16GA from Werner Crossover to 15" woofers and the Horns. I want to try the 12 GA and see what that does. Certainly in reading above the 12GA would be an attractive option for the bass...but what does everyone think about the Horn. Should I stay with my current 16GA, or go 12GA for the Horns as well?
