as far as i can tell 1 person is using the whole name and the other isn't, so i don't know one sub as a greedier own than the other, links to the pages would help.

There is no difference. The 8W7's "full" model number is "8W7-3", the -3 signifying it's a single 3ohm voice coil subwoofer (it's the only voice coil option they come with, so there is no 8W7 that's not a -3 subwoofer).
