I echo 240zracer's comments.
I use Nordost SPM's full range on my Gallo Ref. III's and add Wegrezyn Copper Slams (8 awg) for the second voice coil/sub. I was using my Nordosts for both (they are terminated for bi-amp/bi-wire), but for fun threw some old MIT MH 770's in and heard a big difference. This started my quest for speaker cables that performed well on bass (in my case, <50 Hz)... there is not a lot of information out there.
Good luck,
