speaker cable for bass

I have a pair of subwoofers and I am soliciting for your input on speaker cables that are excellent for bass

"8PR provides sound that is full bodied and powerful, making it ideal for subwoofers and the low frequency section "
Copper is generally very good especially 14 gauge or lower. You definitely need a wire from conductive metal. Stranded is good because it is more flexible and less chance of breaking. Apart from that don't sweat about this issue too much. A subwoofer does three octaves at the bottom of the range where your hearing is least accurate.
Whatever you choose, I would avoid Nordost wires if bass performance is top priority. I would suggest XLO cables as an alternative to the above.
I agree with Ryder - XLO cables, even their cheaper speaker cables such as the Ultra 6, have tremendous bass performance.
