D-I-L-Eye,
Depending on your budget/desire to maximize the output of the Gs, i can say that i found a dramatic change when i switched speaker cables. i used to use Audioquest Crystal from the early '90s. i then bought a pair of very old, used Transparent REference cable...holy smokes, big difference. not a subwoofer, but i was surprised at how much more full it was. i do not know Belden, so i cannot say how good/not good Transp Ref might be...just another thought. good luck.
